From the Publisher
The Divide cantando Learning Kit pairs the audio CD (teaching division facts through a review of skip counting and multiplication) with a 64 page reproducible resource book filled with lyrics, activities and exercises, reinforcing what has been learned in the songs. While the focus of this learning kit is the teaching of division, supporting activities also cover a variety of strands of the new Common Core Curriculum for Mathematics. The audio CD also includes a complement of self-quizzing tracks allowing students to review and quiz themselves.
