*Subtraction Facts to 10*
This game addresses the skills of subtracting within 10. To set it up, distribute the fish bowl cards around the room. Then, give each child some fact cards. Either have them use mental math to solve the problems as they search for the correct fish bowl, or have them write the answer on the card with a dry erase marker first. When the cards have all been sorted, check each one with the group. Discuss which cards have been placed correctly and why some numbers have more cards than others (the number 1 has the most facts, for example.) As a follow up, one cut and paste worksheet has been included.
