Addition Activity 6 – Making 10
Learning to regroup 10 is the last of the building blocks you need to foster. Luckily, we can turn to our two hands for this one.
The first combination to make 10 is obvious: 5 + 5
Next, nudge one finger closer to the opposite hand, you can see the next combination pretty easily: 6 + 4
Continue doing so, other combinations are “jumping out”: 7 +3, 8 + 2 and 9 + 1.
A word of caution here is to slow down. We invented this game of “what’s my cousin” to accomplish this. “I’m a number. Me making 10 cousin is 8. What number am I?”
“2″ they’d yell from the back of the car.
What I was trying to get them to see in their mind’s eyes, is that 8 + 2 are “buddies”, complimentary numbers, in making 10.
Practice this “cousins” as much as your child will let you. Remember dripping water? It will put a hole in a boulder.
Congrats! You’ve done one of the most tedious jobs there is!
While dropping the kids off to school, I’d ask, “
