My daughter is 7 and this is our 2nd year to use RightStart Math. She is in 2nd grade and is adding and subtracting 4 digits numbers with trading like it is nothing. She also can do her multiplications. The most amazing thing is that when she is somewhere and has to spend her money she is quick to tell them how much change she needs back. I have seen a lot of teenagers and adults who cannot do this. THANK YOU!!! Ready to see what next year’s Level D has for us.
