What does "one less" mean?
Counting one less means finding the number that comes right before!
When we count one less than a number, we're taking away just one. It's like when you have 5 cookies and eat 1, then you have 4 left. Let's practice counting backwards from 5!
How to count one less
1️⃣ Start with a number (like 5)
2️⃣ Imagine taking away just one thing
3️⃣ Say the number that comes before it!
Let's practice together!
Example 1: Balloon Pop!
Click on the balloon with the number that is one less than 5:
1
2
3
4
Example 2: Fruit Basket
There are 4 apples in the basket. If we take one away, how many are left?

Parent Tips 🌟
- Use everyday objects: Practice with snacks, toys, or steps - "You have 5 crackers, if you eat one, how many are left?"
- Count backwards songs: Sing counting down songs like "Five Little Monkeys" to make learning fun
- Finger counting: Show the number on fingers, then put one down to see "one less" visually
