This standards-aligned center, designed by teachers, promotes deep mathematical thinking and concept modeling through group engagement. With enough materials for up to six students, it supports Cognitively Guided Instruction, encouraging students to choose problem-solving strategies that make sense to them while engaging in hands-on activities and gamified learning. Students draw cards, move pawns along a path, and model addition as they race both their pawns from start to end, fostering strategic thinking and collaboration. Skill differentiation is built-in, offering two levels of play with simple, shared instructions. The center is inclusive, accommodating various learning styles, and features downloadable Spanish instructions and dual-language activity mats to support language learners.
