Kindergarten math · Unit 1: Counting to 20

One more each time

What this lesson shows

Counters join a row one at a time. Each new number we say means one more counter than the number before.

The worked example

The lesson works this one step by step: 7 apples. Then your kid tries one like it on paper.

The steps

  1. Add one at a time
  2. Say the next number
  3. Each number is one more
  4. One more than before

Helping at home

Read each box aloud. Your kid counts the things, draws one more, and says the next number without counting again from 1. Ask: "Is it one more than before?"

If your kid gets stuck

One more is the next number.
