This is designed to be used with Kagan structures, the uses are limited to your imagination. You can play "Match Mine", "StandUp-HandUp-PairUp", or "Find Someone Who". You can also use it as a math matching center. You can also place a number bond card on a document reader and have students write a number sentence to go with it or vise versa. If you use it for some other activity, I would love to know.
