Help children develop critical and flexible thinking skills with open-ended math problems for which there is no one correct answer! Working in small groups, children use readily available manipulatives to explore various solutions and describe their answers through writing and drawing. Each reproducible activity page can be used and reused multiple times—with larger numbers as children’s skills grow. It’s a fun and engaging way to promote mathematical thinking! Paperback book measures 8 3/8" x 10 7/8" and is 64 pages.
