Addition Show Me Cards are an easy to prep resource for helping students learn sums to 20. These cards can be used as a math center activity in which students can work in a small group, partner up, or even work independently.
In this Show Me Card activity students flip cards over, read the card, and use a whiteboard to record their response. They then show their board to the group to check their answer.
This set includes 30 Show Me Cards and an answer sheet.
