Some groups are so small you can see how many at once, without counting. Look! One. Two. Three. Your eyes just know.
Key idea
You can see 1, 2 or 3 things at a glance.
For the grown-up: Hold up a hand with 1, 2 or 3 crackers and ask “How many?” right away. Quick looks build a feel for small numbers. Make it a game, not a test. Short and happy beats long. Five minutes is a good lesson.
- Try it at home: Show 2 or 3 spoons for a second: how many?
- Roll a die and say the number fast.
- Spot pairs: 2 shoes, 2 eyes, 2 wheels.
