Kids get hands-on practice with comparing numbers—with an instant activity center that makes independent practice a snap! Our ready-to-use center features step-by-step instructions that kids can easily follow on their own: Just set out the materials…then students use activity mats and counters to subtract quantities and numbers! The center has enough materials for up to 4 children to work at once, including a double-sided instruction chart that gives everyone easy access to the activities…and simple picture instructions, so even nonreaders can participate. You get 4 mats with flip number cards, 40 counters, an instruction chart, plus a reproducible write & wipe assessment card.
