This resource provides hands-on, manipulative-based activities keyed to the text that involve future elementary school teachers discovering concepts, solving problems, and exploring mathematical ideas. These activities can be adapted for use with elementary students at a later time. New for this edition, it is now easier to use the print manipulatives that are included with the manual. The manipulatives in the back of the Activities Manual are now perforated, and a pocket in the back cover allows for easy storage of the pieces.
