Moved, but still the same

What this lesson shows

Fixes a mistake

8 stars in a row slide into a circle. None added, none taken away: still 8.

The worked example

The lesson works this one step by step: 8 stars. Then your kid tries one like it on paper.

The steps

1. Count each one once
2. Move them around
3. None added, none taken away
4. Still the same number

Helping at home

Read each box aloud. After your kid counts, move real things, like spoons, into a new shape and ask "how many now?" The answer stays the same.

If your kid gets stuck

Moved, but none added and none taken away: still the same.
