Rainbow Counting Mats 1-20

Twenty bright, hands-on counting mats for your math centre. Each mat pairs a big traceable numeral with a ten-frame and matching dots, so little ones can build numbers 1-20 with play-dough, pom-poms, mini erasers or counters. Print on cardstock, laminate once, and reuse all year. Includes a low-ink black & white version plus a one-page teacher guide with 'one more / one less' extension prompts.
