Today we played Basketball Addition to practice adding three or more 1-digit and 2-digit numbers mentally. This promotes the idea introduced yesterday of finding complements of 10 and grouping those numbers together to find the sum.
Here is a brief video of a group of children working together to add the numbers generated in the second half of the game.
