Some more, some gone

More and fewer.The big ideaWhen more come, there are more. When some go, there are fewer.
How it works
When more come, there are more. When some go, there are fewer.
Count what you have. Then add the ones that come, or take away the ones that go.
Touch each one as you count.
Example 1: Some go
- 3 fish are in the pond. 1 swims away.
- Touch the fish that stay: 1, 2.
- 3 − 1 = 2, so 2 fish are left.
Example 2: Some come
- 3 balls are on the floor. 1 more rolls in.
- Count them all: 1, 2, 3, 4.
- 3 + 1 = 4, so there are 4 balls.
Example 3: Try it with snacks
- Put 4 raisins on a plate and eat 1.
- Count the ones that are left.
- 4 − 1 = 3.
