Counting objects to 20
Count a set of objects to answer 'how many?' for sets up to 20 (arranged in lines, arrays, circles, or scattered)
Suggested ages 5–6
Learning journey
Your child is building essential counting skills — learning that numbers have meaning, that each number represents a specific quantity, and beginning to compare groups to see which has more or fewer objects.
Evidence of understanding
- Accurately count up to 20 objects in a line
- Count up to 10 scattered objects without losing track
- Given a number 1–20, count out that many objects from a larger set
Assessment prompt
If you spread out 15 buttons on the table in a random arrangement and ask Counting objects to 20 how many there are, can they count them all carefully and give you the right answer?
