Color Coding 100's Charts

Have you begun to use the 100's chart with your class this year? 

Remember to color code the return sweeps like this:

 

Why?  I personally have difficulty tracking lines of text, and I know there are students that have the same problem.  It's also hard to learn to visually sweep your eyes from 40 to 41. 

 

A good independent activity is to have students color code the 100's chart that they use on the back cover of their Math Journal also.
