Counting rows to 20

What this lesson shows

15 apples in 3 rows of 5. Count each row left to right, then the next row down: 15.

The worked example

The lesson works this one step by step: 15 apples. Then your kid tries one like it on paper.

The steps

1. Start at the top left
2. Count across the row
3. Go down to the next row
4. The last number tells how many

Helping at home

Read each box aloud. Your kid counts across the top row, then down to the next, touching each thing once, then writes the last number said.

If your kid gets stuck

Across the top row, then down to the next row.
