For warm-ups we tend to use problems students have already done, new problems to provide review, begin a 3 act task, or even use "What do you notice? What do you wander?" but what about using a brain teaser?

What is feedback in Math?
When I first started teaching, no one spoke about feedback in math. It was pretty much assumed that correcting the assignment, was valid feedback but in reality it really wasn't because very few students actually looked at their work again.
Since then, research has shown how important proper feedback is for students but it's only recently I've found better ways of providing it and having students pay attention to suggestions.
Feedback is a way for students to know how well they are progressing towards a goal. It lets them know what they've learned and what they still have to learn. It is a way to move from teacher oriented to student oriented.
It is important to connect feedback to learning targets and success criteria. Remember learning topics cover what the student is expected to learn while the success criteria is what they use to see if they've met the learning target. If a student can look at the learning target, the success criteria, their work and are able to judge where they are in the process, they are providing their own feedback.
Furthermore, teachers need to make sure that any feedback provided is based on evidence. All assignments need to be aligned with the learning target and the feed back should be very specific, based on the work done rather than relying on inferences. This means feedback should be based on the quality of work, not the student. In addition, the teacher should use student work to note which areas need improvement and how to make those improvements.
Because the feedback is specific and meaningful, students are able to take the information and to make changes. It is best if the feedback identifies one thing to change which leads to immediate improvement. It lets the student know how close to meeting the criteria of the learning target they are and offers them direction to make it.
In addition, feedback needs to written in such a way as to both engage and motivate them. It should also be useable and not overwhelm them. It is suggested that the teacher meet with students to make sure they know what makes quality work and understand the feedback given. It is also suggested that students repeat back what they heard.
All feedback needs to be given in a timely and ongoing manner so students have time to make changes. As soon as students are given feedback, they should be given a chance to act upon it. If the feedback is given while they are working, they can connect it to the learning target and success criteria. This also helps students listen and retain their mathematical learning. Furthermore feedback should include information on content, skills, and Standards of Mathematical Practice.
Feedback does not have to be given only by the teacher. Give students an opportunity to talk to each other so students get feedback from their peers. The conversation should include questions beginning with "Why" or "What" or "Can you explain?" Questions that require explanations and justification. Let me know what you think, I'd love to hear. Have a great day.

Turning Textbook Questions Into Open Ended Questions.
Furthermore, students get used to the idea that all questions have one answer when in reality that might not be true. For instance, if you are buying new cabinets for your kitchen, the cost is often dependent of the type of wood used, the type of cabinets, and size.
So to change textbook questions into open ended questions, there are a couple of different ways to do it but there are some things to keep in mind. One needs to identify a mathematical topic or concept to address. Think about how to express the question so that it has several possible answers rather than just one.
One way to accomplish this is to take look at the question such as "What is the perimeter of a rectangle that is 13 inches long and 8 inches wide" and find the answer - 42 inches. Rephrase the question " Construct two rectangles with a perimeter of 42 inches. This question has more than one answer which makes it a better question.
Other strategies one can use to convert open problems or questions into open questions include turning the question around by asking the student to suggest ways to get the answer instead of finding the answer. Ask the student to identify similarities and differences such as in "How are 85 and 90 similar?" "How are they different?" This question might lead to a student saying they are similar because they are multiples of 5 but they are different because one is a multiple of 10 while the other is not.
Ask students to explain something such as "6 is a factor of two different numbers. What else might be true about two numbers?" This could lead to something like "If 6 is a factor of two different numbers, the two numbers are also divisible by 2 and 3." Have students create a sentence such as "Create a sentence that includes the numbers 5 and 8 with the words "more" and "and"?". You might end up with a response of " The product of three and four is more than 10." Include soft words such as almost or nearly such as "You multiply two numbers together and the product is almost 600. What might those two numbers be?"
If you are want to rewrite word problems to make them more open ended, there are six different things one can do to make it open ended. The original problem from the book read " How many nickels are in 55 cents. The first thing is to remove all restrictions so it reads "How many coins does it take to make 55 cents? Students have a choice of which coins they will use to answer the question. Second is to remove the known so you might say "I have a closed handful of nickels, how many do I have?" This requires students to estimate a reasonable number of coins.
Third way is to swap the known with the unknown and remove the restriction so instead of saying nickels, write the question so it is more general "I have 5 coins, 3 are the same, how much do I have?". Again students have a variety of choices from pennies to nickels to dimes, to quarters or even half dollars and dollar coins. Fourth, one needs to remove the known and the restriction and change the unknown such as I have 5 coins, how much money do I have?" Finally change the known, unknown, and restriction such as "What is the shortest or longest line that could be made with 5 coins?" or "I have some coins in my hand, how much money might I have?"
It doesn't take much to change the closed question into an open ended question. Let me know what you think, I'd love to hear. Have a great day.

The Answer Is.....What Is The Question?
There is a joke I often heard my father crack when I asked him for help. He always replied "The answer is 42" which it never was. At least for the problems I was doing. When I stumbled across a image with "The answer is..... What is the question?", I realized I had another open ended question exercise I could use in class.
This activity involves giving students the answer and letting them come up with the problem or question associated with it. The teacher provides the answer such as 42 while asking students to create a problem whose answer is 42.
One student might come up with 41 +1 or 43 - 1 while another might use 7 x 6 or 168/4. There are as many possibilities as there are students. This problem requires students to think about what problem yields this answer. Someone might even come up with 4 x 10 + 2.
This type of activity is not restricted to only numbers, it could involve measurements such as the answer is 42 cubic feet. The cubic feet immediately indicates a cube or rectangular prism with a volume of 42 cubic feet. This means there are fewer possibilities but still quite a few ranging from 42 x 1 x 1 to 2 x 3 x 7. This type of problems uses the measurement to provide context which students do not always pay attention to.
Another type of problem could have an answer of x = 3 indicating the problem might be a one or two step equation or even one that has variables on both sides of the equation. The context indicates it has to be an equation with at least one variable - x and when solved has a value of three such as x - 2 = 1 or 2x + 3 = 9 or 3x - 2 = 2x + 1.
Then there is the answer of 1/2 pizza which might require the student to create a word problem to have this answer. The problem might be that three boys purchased two pizzas which they ate 3/4th of the total pieces, how much is left? or they might write, Dad brought home a pizza for dinner. Out of 12 slices, we ate 6, how much was left? Both problems can be answered with 1/2 a pizza.
The answer is..... what is the question? activity has students go beyond the usual procedural methods to using higher level thoughts to determine how they get to the answer. Furthermore, the activity helps students to make mathematical decisions, while applying mathematics to new situations. In addition, using this activity can help create a culture where students feel free to try different paths to get to the requested answer.
It also provide automatic scaffolding because students use the type of math they are most comfortable with to come up with the question. It also encourages students to feel successful because their question, as long as it gives the answer is correct and as they feel more confident they are likely to try and be willing to make mistakes.
Let me know what you think, I'd love to hear. Have a great day.

"Which Would You Rather?" Open Ended Questions.
It is important to incorporate open ended questions in math that encourage math-based conversations and helps students learn to justify their thinking used to support their thinking. The best thing about an open ended question is that there is no one answer. These types of questions encourages higher level thinking to solve problems. In addition, open ended questions allow students to see that it is possible to use different ways to solve the problems and can produce more than one answer.
By having students open ended questions, they gain confidence in themselves because struggling students can use basic skills to find an answer while more advanced abilities can use different skills to find an answer and both are correct. If the problems are written well, they easily become engaged. Furthermore, open ended questions encourage students to utilize creativity to solve the chosen problems.
In addition, student responses to the problems can be used by the teacher to assess their level of understanding and ability. Open ended problems provide informal assessment but the teacher can see the thinking used to solve it, the methods used to solve it, and their understanding of the situation overall.
The last thing about using open ended math problems is they can be used as warm-up or bell ringer problems, independent, small groups, or even whole class. When introducing the use of open ended problems, it is important to model the process which can be done as a whole class activity. Another time, students can work in pairs or small groups to find an answer to the problem and share the answer with the teacher via a video or google classroom.
I read about the “Which would you rather” activity in one of Matt Miller’s blogs. I wondered how I could use it in my math class because math is a bit different. I found a site which provides “Which would you rather?” Activities to help get started. There are quite a few already created to start you off.
The selection offered at this site has quite a few ready to use questions for grades K to 12, enough for several months if you do one a week. Each “Which would you rather” possibility are very open ended. The answer may depend on what you prefer, while others make the person think about the differences based on the situation.
One has students decide which possibility would you rather? The situation is that you and two friends want pizza for lunch. If you buy one pie and get a 10% discount, buy two pizzas and get 20 % off, and buy three pizzas to get 30% off. Would you prefer Option A where each of you buys an individual pizza or option B where one of you buys three pizza on one check and you split the cost with the others.
It is nice to have a separate worksheet for students to fill out as they work through the question. The worksheet should have a way for them to say they prefer option ? Rather than option ? because. There should also be a place for them to show their work and what things did they consider as they began the problem.
There are other types of open ended questions that I’ll cover another time. This is something I could easily send home for students to work on because there are no correct answers they can find on the internet and they can’t do it via some app like photo math. Let me know what you think, I’d love to hear. Have a great day.

What To Think About When Creating Any Assignment.
Yesterday, I discussed some general points to think about when creating an assignment but today I’ll be exploring parts of the assignment in more detail. When looking at creating an assignment, it is important to think about what the assignment being anything that is assigned to students from the warm-up to the exit ticket and everything in between including the actual assignment focused on learning the content.
First one needs to look at the type of assignment being given. Is it a short task of under 15 minutes such as bell ringer, journal entry, or the exit ticket or is it a task spread out over two days or is it a project that takes longer than two days such as a performance task. Does the assignment focus on content standards associated with the grade level or does it use standards from other grades. Does the assignment include any mathematical practices. Are the directions clear and easily interpreted by the student.
Next, does the assignment require high levels of cognitive thinking of the students. If the assignment does not require higher levels of cognitive thinking, look at how you can change or adjust it so it demands more. This includes warm-ups, journal entries, and exit tickets.
Think about the rigor involved in the assignment. Does it allow students to develop mathematical understanding of the skills and processes as well as concepts. Does it provide opportunities for developing an authentic understanding of math via the use of multiple representations. It is important to use multiple representations of the material because that makes it better for students to learn the material.
Does the assignment help students learn to discuss topics mathematically? Does it ask students to provide a response to an argument, justify a response, or explain their thinking to others while using the language of mathematics. Did the assignment include opportunities for whole class discussion, small group conversations, or talking between peers. It is important for students to develop the ability to converse mathematically.
Does the assignment help students bridge their understanding from unknown to known and does it make the math feel relevant to students even if the material feels foreign. Does the assignment provide choices for students so as to support their autonomy. In math the choices could be in which problems they can do or the method of doing the problems such as flipgrid, or a video.
Finally, is there scaffolding included in the assignment and what type is it. Is there scaffolding written in for a part of the assignment or for the whole assignment? If only a part of the assignment, what is the scaffolding and why is it used only for that part. Is the scaffolding done via a graphic organizer? Is the material broken down into small chunks? Does the student have a list of steps to follow?
So when you are thinking about creating assignments, especially now after students having been out of school since the beginning of the fourth quarter, it is important to include scaffolding and to look at all of these items to create assignments so they are the best for students.

Creating Effective Assignments
I suspect the books you use in math are similar to the ones I have in that the teachers edition has recommended problems for basic, normal, or advanced. The assignments are a bunch of different problems students are expected to complete and turn in. The problems are always in order and coincide with all the examples.
Unfortunately, that is not the best way to assign problems especially if you want students to learn. Today, I'm touching on a few changes to make the assignment better.
1. Figure out what the objectives are that you want students to meet and decide how they will show they've met that objective. To do that, begin with rewriting the learning objective as "I want my students to be able to: ____________". In addition, use active verbs when writing the objective such as compare similarities or discuss differences, or explain the steps necessary to solve this type of problem.
2. Try to make the assignment more interactive and interesting than just straight problems. See if there is a way of designing the assignment to make it creative and challenging while motivating students at the same time. Think about how you can change the assignment up so it is no longer the "do every third problem". Perhaps you can change it to "Write a letter to a friend explaining how to do the problem because they were sick that day" or "Create a video showing how to check your work for this type of problem."
3. If the assignment does include problems from the book, make sure the problems are not in the same order as in the book. Instead of assigning "Every third problem", maybe do 2, 10, 22, 4, 12, 24 so the problems are mixed up. This helps students learn the math better.
4.Once you've created the assignment, go back and make sure the assignment still meets the learning objectives. If the learning objective requires students to compare and contrast two things and you only have the comparison in the assignment, you'll need to go back to include the contrast part.
5. Think about how to order assignments so skills are built in the proper order. You want students to build the necessary skills incrementally and make sure students see the connection between what they already know and what they are learning. If you plan to end the semester with some sort of project, make sure the smaller assignments build all the skills they need to complete the project.
6. Determine the frequency of assignments and how often they need to be turned in. Will students complete an assignment for each section or for two or three sections with a few problems from each section. Normally, I'd recommend having a calendar of assignments and due dates completed prior to the beginning of the semester but with the coronavirus, that might not be as easy to do.
7. Think about the ability of students to get the assignments done. Will they have enough time or so they struggle and need additional time? This is important when creating assignments because more is not always best. Do students really need to complete 20 problems for every section or will 10 be enough especially if you ask them to discuss how to do it or talk about issues they had working the assignment.
This is just an overall look at creating good assignments but on Wednesday, I'll be looking at questions one needs to answer in more detail when creating an effective assignment. Let me know what you think, I'd love to hear. Have a great day.

Using Multiple Choice Questions In Class
Personally, I don't like using multiple choice questions in class but many standardized tests such as ACT or SAT use them and most of my students struggle with this type of question. On many of the standardized tests given by the state have the right answer, two wrong answers that students will come up with if they don't take the problem to it's natural conclusion or only get half done and one that is totally wrong.
Even though I don't like giving this type of test, it is important that students learn to take them and not just guess. In my textbook, the pre-tests for each chapter are multiple choice along with certain questions in the problems for each section. Many students need to be taught how to take multiple choice tests effectively.
There are strategies to help students when taking multiple choice questions. First, students should cover up the potential answers without even looking at them before they read the problem because they need to know exactly what the problem is asking. If they cover the answers, they do not get distracted and they can reread the question multiple times to understand it.
In fact, it is recommended that students rephrase the question to themselves, before trying to answer it in their mind first. If the problem requires calculations or simplification, students should try to answer the question before they look at the answers otherwise, many students tend to guess rather than trying to do the problem. If the problem requires them to find an equivalent equation or find a fraction closest to a number, they should still cover the answers to they are focused only on the question before going through each answer slowly to see if the answer goes with the question.
Secondly, have students highlight key words, especially words like always, never, sometimes, not and others that place limits on the situation. The question might ask you to find the probability of not drawing a red or green ball, rather than asking for the probability of drawing a certain colored ball. Many students miss the qualifiers if they don't highlight certain key words.
Next, after reading the question and highlighting key information, students should read through the answers to eliminate any that are obviously wrong. If a student does not see any that are obviously wrong, then there is another technique to use. If the answer required is an actual number, one can substitute the answers back into the original equation to see which one makes the whole problem correct. I've used this last one myself on multiple choice questions.
One person analyzed over 2400 questions from 100 different tests to determine the four strategies to help increase a person's chances of getting multiple choice questions correct when they don't know an answer. First, if you have see "None of the above" or "All of the above", one of these is likely to be the correct answer over half the time. Secondly, two questions in a row seldom have the same answer. For instance if you don't know the answer to question 2 but know the answer to question 1 is a and the answer to question 3 is d, then chances are question 2 will not be either a or d. Next, the correct answer is more often than not the longest answer because the people who write the test want to make sure the correct answer is definitely correct. They are not going to take as much care with an answer that is wrong. Finally, eliminate any questions that are out there. Often, on math tests, people can eliminate answers that are too small or too large just by using estimation.
I also tell students to keep an eye on the time if the test is timed. Always do the questions you know how to do first, followed by those you sort of know, and leave the ones for last that you have no idea how to do. You can do this for some computer tests but not for all and it works well for paper based tests. I advise students to spend no more than two minutes if they get stuck on a question otherwise they'll get frustrated and not be able to complete the test. I also include some practice questions with their homework. Let me know what you think, I'd love to hear. Have a great day.

Always, Sometimes, Never?
If you've never seen or done one of these activities, they are fairly simple. Students are giving between two and five statements to look at. They have to decide if the statement is always true, sometimes true or never true.
When teaching mathematics, statements are made which are only true in certain contexts and usually the context is what is being taught. This activity allows students to think critically about math to determine when things apply or don't apply. Furthermore, it promotes mathematical reasoning and introduces the idea of counter examples to prove something isn't always true.
It is important to have students provide counter examples for sometimes statements because it helps students see the context of when it is true or false and requires deeper delving into the statement as they think about it. Determining if the statement is always true, sometimes true, or never true requires higher level critical thinking skills rather. In addition, this activity helps identify misconceptions in student understanding.
The always, sometimes, never activity also promotes dialog and communications because students are required to explain why the statement is always true, sometimes true, or never true. It is a good activity to help students learn to "Justify their answer" which is often seen on tests.
Overall, always, sometimes and never activities are considered low floor with a high ceiling because students who have low mathematical reasoning skills can still participate by substituting numbers to see if it seems to always be true or find a counterexample. It is high ceiling because students have to justify their conclusions. Furthermore, always, sometimes, and never is also a way to introduce logic statements to students without using straight mathematical language and theorems.
Always, sometimes, and never also helps students develop perseverance as they look for examples or counter examples. They build arguments while evaluating their logic and the logic of their peers arguments. It also has students engaging in authentic mathematical thinking.
When doing this with students, they often will try one number to see if it works but they will need to be guided into trying several possibilities such as zero, fractions, or negative numbers and not to just accept the first possibility. Take the statement "Any number added to five gives a number larger than five" which on the surface seems to be true because people automatically assume one or above which makes this true but if you add a negative number to it, the answer will be less thus making the statement, sometimes true.
So if you want a way to help student develop mathematical thinking, this is a good way to do it. Let me know what you think, I'd love to hear. Have a great day.

Taking Notes From The Textbook.
Currently, research indicates when students use pen and paper to take notes, they are better able to retain information when compared to using digital apps such as Evernote.
Furthermore, when taking notes by hand, it means a person does not have to toggle back and forth between the class and pages or other note taking app. One can also watch videos or streaming lectures while jotting notes down. When students first learn to take notes, they try to take down everything they can. I know in college, I'd try to write everything down but I'd go over notes later to make them neater and to make more sense.
One should not try to write down everything because it can lead to information overload, which limits the amount of material a student is able to recall later. Since most classes require reading, it is important to jot down notes while reading and don't be afraid to draw pictures or diagrams.
I want to focus on teaching students to take notes from their textbooks during the time they work at home since I won't have as much time available during class. In math, taking notes is a bit different than for English or History and most of my students do not have those skills yet. In addition, reading and taking notes from a math textbook should be done when the student is alert.
It is recommended students write down definitions, key concepts, and theorems in their own words rather than copying them down verbatim. If they find terms they don't understand, they should look it up and make notes. When writing down definitions, they need to include examples of things that meet the definition and those that don't. As for theorems, students need to read those carefully and determine why they apply in various situations.
When the student comes to the example or application of the theorem, they need to look carefully at them, working on understanding each step in the process, and once they've finished, they should try working the example or application of theorem without using the book or notes. In addition, as students work through examples, check the end of the chapter to which ones are like the ones just done and try those. If there is something students don'e understand, they should ask the teacher.
Furthermore, students need to read the text slowly because mathematical texts are extremely information dense and they need to pay attention to understand everything. Students need to be prepared to read and reread the material sentence by sentence, paragraph by paragraph to comprehend the written word. Take time to analyze all the diagrams and pictures. When looking at a picture, students need to identify how it relates the the topic.
This is important to help students learn to take notes from the textbook. For the first couple weeks, I have to send work home, I am going to include a partially started set of notes students can copy into their composition books and finish on their own. This is the only way, I'm going to teach them to take notes when reading. Let me know what you think, I'd love to hear. Have a great day.
