Imathland

This is an app I found in the App Store for math. I decided to download it and check it out because I'm always on the lookout for apps that are better than those that write out the information and you just read.

The description made it sound a bit better but you never know until you give it a try.  The app just has the name when it opens up but if you hit the button on the top left side, you get a menu telling you what topics it covers.  Some of the topics include trigonometry, polar coordinates and order of operations.

The menu has drop down arrows so you know there is more than just the topic.  When you hit the arrow, you get the exact material covered in the section.

This makes it nicer because you know ahead of time what you will be looking at.  Unfortunately, some topics have more of a general presentation such as trig and polar coordinates while others get much more detailed such as in order of operations and linear equations.

The nice thing is no matter which type of presentation it is, the material is covered in a very interactive way.  For just about every screen, you are required to input some sort of information and you get immediate feedback.
The section on graphing linear equations

The graphing linear equations covers all three forms.  It has you select the form you want and then you must put choose values so the application can show you where the numbers are substituted into the formula.

If you notice, I was asked to select a b and a m for the slope - intercept form.  Once I select the value from the drop down menus, the program takes the values and shows me where they go into the y = mx + b using one color for the slope and another for the intercept.

It is great since it makes you a part of the teaching process rather than providing all the notes.  Once the equation is shown, the program goes on to graph the equation using animation so you see the starting point and the line.

This screen shot is out of polynomials.  It shows how to combine like terms with an explanation of what is going on and what you need to do.

The next screen has you try it yourself.  Again if your answer is correct, it turns green, if it isn't correct, it turns red so you get immediate feedback.

The only thing is that it doesn't tell you why you missed it only that you did get it wrong.





As you can see, I did one of the addition problems of 6x^3y^2 - 10x^3y^2.  I got the answer correct. down below the problem it told me I needed to use the ^ to indicate it was a power.

Although this still has a few things I'd like to see, it is more interactive than many others I've seen and the best thing is that it is free.

If you've used it let me know what you think of it. I'd love to hear.  Have a great day.
