Included are 36 related addition and subtraction cards, a cover sheet, and a direction sheet. I prefer to cut the cover sheet and direction sheet in half, glue it onto a small manila envelope, laminate the envelope and cards, and store the cards in the envelope. Whenever I need the center, I simply grab and go! No prep needed!
With this center, students match addition facts to their related subtraction fact with this 36 card game. Cards do not include sums/differences, to make this more challenging and force students to add and subtract (ex: 15-8, and 8+7).
I hope your students enjoy this as much as mine do!
