Watch Mr. Aube and his son Lucas show you how counting on works!
How It Works — Step by Step
1
Look at Both Numbers
Start with your single-digit addition problem. Example: 4 + 5
2
Put the Bigger Number in Your Head
Find the larger number and hold it in your mind. In 4 + 5, put 5 in your head.
3
Count On the Smaller Number
Starting from 5, count up 4 more: 6, 7, 8, 9. You can use your fingers to keep track — that's perfectly fine!
4
You've Got Your Answer!
The last number you said is the answer.
4 + 5 = 9! 🎉
💡
Mr. Aube's Tip:
It's totally okay for kids to use their fingers when counting on! If it's a strategy that works for them and that's the stage they're at, let them be confident. Taking away their fingers won't build confidence — it'll do the opposite!
