### PRODUCT DESCRIPTION

This guide was designed to help teachers use a rekenrek to teach students how to visually recognize a number as two sets of combined objects, how to compare two sets of objects using the matching strategy, and how to construct and deconstruct the same number in different ways. The guide shares a weblink to a free digital manipulative, instructions for using the manipulative, suggested uses, and four example activities.
