This is a wonderful resource created by Selena at The Learning Leaf to help students explore and introduce them to:
- essential addition facts of 10
- odd, even, and square numbers
- introduction to the commutative property of addition: a+b = b+a
These cards were made using 1" circle counters. A sheet of circles is included on the last slide, to cut and print if you want/need to make your own counters.
Each pdf sheet can be printed on cardstock or laminated for longer use. Students place the counters on the sheet and calculate the addend to find that each of the facts equals to 10. All facts were included (i.e. 2+8 and 8+2) to aid in the development of the concept of the commutative property of addition. The layout of the circles for each number aids in the conversation and concept development of odd, even, and square numbers.
