My eight year old daughter has a learning disability that really shows up in math. When learning a simple addition or subtraction fact, she’d perfect, and then forget. After flashcards, software, other workbooks, tutoring, manipulatives and summer school, I decided to try Two Plus Two is Not Five.  I can see now that she “gets it.” She can recall the trick when she sees the numbers. She is so excited about being successful and absolutely loves math. The book may anchor my daughter’s academic future. Thank you.
