Multiplication In Middle And High School.

 

Due to Covid, I have students who do not know how to multiply or divide and can barely add or subtract.  It is well known that many students missed out on learning and practicing this due to not being in school.  In addition, we know that students do better when they know their multiplication tables solidly and know how it relates to division.  Students who know their multiplication tables are better able to see patterns, relationships, while supporting more complex mathematical processes.  

Fortunately, there are ways to help students practice their multiplication tables in class without losing too much time from the regular instruction.  Think about using apps or websites that allow students to practice their multiplication.  Do not go for sites that only drill them repetitively since drilling does not always work.

Think about providing a multiplication chart but have it filled only with the facts they have not learned so the ones they know are blank. If they know their facts up to 6x6, then the chart would only have the facts beginning with 6 x 7 and above.  Or think about using factor triangles with the 6, 7, and 42 so they see the relationship between multiplication and division.

Furthermore, take what they know a step further.  If they know 6 x 6 = 36, then take time to help show them understand that 6 x 6 means 6 groups of 6 so 7 x 6 is seven groups of 6 so they know they are adding one more group of 6.  It is also important to help them see that 6 x 7 can be seen as 6 groups of 7 which still gives them 42 objects. When teaching nines, do the finger trick so they can easily find the answers with their fingers.

Start the year with multiplication facts via warmups or bell ringers.  You could use a mad minute worksheet or one that is blank multiplication chart where students write in what they know so you have a better idea of what they don't know.  

Think about an online math station by having students enjoy something like Math Dash Ninjas. This site has you choose a grade level and math topic to practice.  The idea is that for every correct answer, you get dodges but students do start with some so if they make a mistake, they can still avoid being hurt.  It is fun and done well so students have a chance to answer.  

Think about having practice on Friday via Kahoot or Quizz which have premade games.  I've used time on Friday to have students practice writing equations from word problems by playing Kahoot. They like it a lot.  

These are just a few ways to help students practice their multiplication. Let me know what you think, I'd love to hear.  Have a great day.
