Extensions in Mathematics correlates to the Everyday Mathematics® Series for Grades 1–3, Grades 4–6
I love this series because it is a systematic way of teaching students how to solve problems and how to write about their solutions. The kids really seem to like how the book steps them through how to write about their thought process. I love the sample explanations!
