The Math K5 Teacher’s Edition, 4th ed. provides instruction for the use of manipulatives to introduce each new math concept for a hands-on approach to learning. Through practice and interactive questioning by the teacher, the student gradually progresses to an abstract level in which he uses only numbers. Core-math concepts are reviewed periodically for retention and reinforcement. Daily classroom review provides a 5-10 minute practice of a previously learned skill. Chapter reviews along with cumulative reviews and section reviews provide additional opportunities for review.
