Students recall subtraction facts within 10 for subtracting 1, 2, or 3 (e.g., 9 − 2 = 7). They use count-back or known-fact strategies.

Subtract 1, 2, or 3 means count back.
Each hop back is one less.
7 + 3: start at 7 and count on 3: 8, 9, 10. 10 − 3: start at 10 and count back 3: 9, 8, 7.
Starting at 7 saves you counting all the way up from 1 again.
Each hop is 1 more, so 3 hops from 7 land on 10.
To take away, start at the big number and count back instead.
Start at the big number. Count on to add, count back to take away.
Saying 7 as the first count, and landing on 9.
7 is where you start. The first hop says 8: 8, 9, 10.
6 − 2 = ___ — 4. Start at 6. Count back 2: 5, 4.
You have nine stickers. You give two away. How many do you have left?
We can write this as nine minus two equals — what?
Let's use a number line to count back.
Start at nine, because we begin with nine stickers.
Count back one: nine… eight.
Count back one more: eight… seven.
We landed on seven.
So nine minus two is seven. When you subtract one, two, or three, just count back. Great job!
