The second website I use is www.aaamath.com. I often use it for my Algebra I or Pre-Algebra level students who need to practice various topics. Today I'll be sending my students here to read and practice prime factorization. This website has a topic, information on doing it, practice and often offers games. My 9th graders tend to be much more focused in class when they have an iPad assigment.
I gave some thought to mindmapping last night and came up with a couple ideas of how to use it in my math classes. So far the ideas are for geometry but its a start.
1. Use it for classification of triangles. The center topic of triangles has three arms. One for angles, one for sides and one for both. There are more arms off of each of those topics to list the type such as right, acute, scalene or right scalene. Add more arms for the characteristics such as acute would have three acute angles, or right scalene might list must have a 90 degree angle with three different length sides. A 30-60-90 degree triangle would be an example.
2. Classification of quadrilaterals. This would work the same way as the triangles one.
3. Altitudes, bisectors, and medians.
This could easily be done on a mindmapping app on the iPad. I use Simple Mind. It is free and it allows you to use a different color for each branch of the map. Students often remember color better than something in black and white.
I'll give some more ideas for mindmapping in a day or two.
