COLLABORATIVE NUMBER SYSTEM COMMON CORE CARDS by DIDAX
Practice and reinforce the content from the Common Core State Standards with these innovative activity card sets. Students first solve the problem on their own card; then students with the same answer form collaborative groups for further problem-solving activities. Or use cards in smaller groups to give students additional practice with the content they need to know. Each set contains 120 cards, 40 cards per grade level, that can be assigned on- or off-grade level as necessary. Durable, two-color cards measure 4" x 6". Teacher's guide provides complete instructions, including suggestions for problem-solving lessons for the collaborative groups.
