Students can sort the cards by matching the ten frame with the number, or play a game of memory/concentration with a partner. Print to card stock and laminate makes it a perfect activity for your math center.
This bundle includes two versions which makes it easy to differentiate. There is a color-coded version and a black and white version. You can also differentiate by giving less cards (1 -10) to students who struggle and challenge other students by using all 1 - 20 cards.
