Stop buying more counters. Use the children.Five kids, photographed in every decomposition of 5, posted at eye level all year. Decomposing number is THE conceptual achievement of the early grades (Resnick, 1983), and the body makes it stick. Zero dollars. Huge payoff. AI kids here for privacy.. see my pinterest board for different real classroom examples....pinterest.com/pin/1420041944… #MTBoS #mathchat #mathchat #wcydwt
