Using random order to practice facts, the "Wrap-up Rap" goes through each set of problems three times---once with answers, once without, and once at a faster pace. If a student can successfully keep up with the faster pace, they've most likely mastered the facts! For use individually or with Learning Wrap-Ups, this "Wrap-up Rap" will teach your children basic addition facts. 1 CD. Grades 2-6.
