Using flex cubes to teach regrouging will show students how math works. A color for one number and a different color for another number will help students understand the relationship numbers have with each other in addition and subtraction. For example in the problem of 37-8 students can see that 7 is not enough to take away 8 but if regroup by making the 3 a 2 and adding 10 flex cubes to the 8 you can then subtract 8 from the 17 (10+7). Modeling addition and subtraction is extremely important in helping students have a life long understanding of just what happens when you add and subtract problems. Once understanding is achieved with relationships of numbers then students can begin to use concrete forms of numbers for calculating the answers.
