These professional books by John A. Van de Walle and LouAnn H. Lovin are outstanding. Their student-centered, problem-based approach helps students develop confidence and a deeper understanding of math.
Over 200 grade-level appropriate activities are included, as well as access to a website with blackline masters. Each edition is an invaluable resource for one-on-one conferring or small-group work, providing instructional support for teachers who need to teach a concept, skill, or fill in missing pieces for a student.
