Gakuva’s recommended starting approach is selected. You can still compare every option.
2 approaches
Counting answers “how many?” Touch one object for each number word and stop on the last object. Arrangement can change, but careful counting still finds the same total.
Spend about 10–15 minutes counting the same set in a line, then scattered, then in a circle.
Count each object once in several layouts and count out a requested set.

Check 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
“If you spread out 15 buttons on the table in a random arrangement and ask your child how many there are, can they count them all carefully and give you the right answer?”
