Math Coachs Corner: Deal Out 20. A recording sheet and deck of cards is all you need for this quick little workstation activity. Students choose two cards and fill in the amount on the ten frame. Then they use the ten frames to figure out how many more to make 20.
Math Coach's Corner: The Ten Wand--for K, I'd have as mixed bowl of red and blue unifix cubes (or any 2 colors). Kids use a scoop or serving spoon to put 10 on their workmat, then sort, snap cubes together by color to discover how they made 10.
