Maria Miller, a math expert, maintains 2 websites and she offers wonderful, creative math resources for parents and teachers - we have arranged with her to include our programs free with her offerings - she has several bonus options. We invite you to visit each to check out her offerings. (NOTE: we recommend that you start with MathMammoth - the 2 sites are linked but you would use MathMammoth to order most products and receive the free bonuses.)
