TrixieB Posted November 9, 2011 Share Posted November 9, 2011 My kiddo who is using Singapore 5A (U.S. edition) needs much more practice with bar diagrams. There are so many supplemental books... Intensive Practice, Extra Practice, Challenging Word Problems, and probably more that I can't think of... Which supplemental book(s) give extra practice with bar diagrams?
