One Less
Say how many after one goes away, up to 5.
Warm-up, learn, try it together, practice, then a quick check. 10 minutes or less.
For grown-ups
Your child says how many are left when one is taken from a group of up to 5. We suggest reading it together.
What children learn in Level 28
- There are 4 donuts. Leo eats 1. Yum! Now there are 3.
- One less is the number just before when you count. One less than 4 is 3.
- Your turn! There were 5 bagels, and 1 was sold. Tap to count the ones that are left.
- When one goes away, the number gets smaller by one.
- Try it with a grown-up! Put 5 crackers on a plate. Eat one. How many now? Keep going until there are zero!
