Which has more?
The big ideaMatch them up. The group with some left over has more.

How it works

Match them up one to one. The group with some left over has more.

The group with none left over has less.

It doesn't matter how they are spread out: count or match.

5 balls• 5 in a tower1 car• 1 car• the balls have more
Match them up.

Example 1: Which has less?

  1. 5 balls and 1 car.
  2. Match each car with a ball.
  3. The car is used up, so cars have less.

Example 2: Which has more?

  1. 5 blocks in a scatter and 5 apples in a line.
  2. Match them up: nothing is left over.
  3. They are the same, even if they look different.

Example 3: Spread out

  1. Spread the same toys wide.
  2. They look like more but aren't.
  3. Count to be sure.
