Note: You could also use ten frames with this game. After kids spill their counters on the table, they place the counters on ten frames. Kids see that 13 equals 1 ten and 3 ones, which helps with place value skills!
Have kids compare their number bonds. One friend could have 9 red and 4 blue. While someone else ended up with 3 red and 10 blue! Kids see various combinations of two numbers that equal the same whole: 13.
If you want to take the activity further, you could have kids write out the fact family for their number as well. However, this would take the fun out of the game!
