When one more comes, the number goes up by one. It’s the next counting number! 3 and one more is 4.
Key idea
One more is the next number when you count.
Worked example: One more block
Sam has 4 blocks and gets 1 more. How many?
- Start at 4.
- The next number is 5.
Answer: 5 blocks
For the grown-up: Build a tower and add one block at a time, saying the new number each time. Ask “What if we add one more?” before you add it, so your child can guess. Stop while it is still fun. Then go and play the real-life version.
- Try it at home: Add one block at a time to a tower.
- Drop one more coin in a jar and say the number.
- Sing a song where one more joins in.
