You can use these cards in many different ways. The way we use this in my Kindergarten classroom is to play memory and/or match the cards. At the beginning of the year we just matched the ten frames with the correct number. Now that my kinders are reading, they match all of the cards (ten frame, number, and number word). We have even put two sets of the cards, either the number/ten frame or ten frame/number word, face down and they play it like memory. I would suggest laminating the cards and printing them on cardstock for durability!
