Book & CD. The Suma cantando Learning Kit pairs the audio CD (which teaches addition facts to 18 in Spanish) with a 64 page reproducible resource book filled with activities and exercises, reinforcing what has been learned in the songs. While the focus of this learning kit is the teaching of addition, supporting activities also cover a variety of strands of the new Common Core Curriculum for Mathematics including: the commutative and associative properties of addition, finding missing addends, measuring length, telling and writing time, organising, representing and interpreting data and understanding basic shapes and fractions. The audio CD also includes a complement of self-quizzing tracks allowing students to review and quiz themselves.
