Do you have a student that struggles with math basics, such as mental math as well as addition and subtraction fact families? If so, you are bound to see success with him or her with Math-U-See supplemental math program called Accelerated Individualized Mastery (or AIM). A manipulative-based math program, AIM focuses solely on add/subtract math facts to build that mental math strategy. Once your student has mental math down, the future concepts of math will come so much easier! Check out my review of AIM!
