The idea is to hop to the number based on the number sentence I give you to complete. R8 did some multiplication (can you believe she is a third grader already??) I-6 did some addition and subtraction to practice his first grade math.
When J3 wandered in, he couldn't be left out so he got to identify numbers. You know he can pretty well read numbers 1 to 10. Not bad for a 3 yr old!
