Book & CD. The Multiplica cantando Learning Kit pairs the audio CD (which teaches multiplication tables to twelve) 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 multiplication, supporting activities also cover a variety of strands of the new Common Core Curriculum for Mathematics. The audio CD, which incorporates skip counting in each chorus, also includes a complement of self-quizzing tracks allowing students to review and quiz themselves.
