Making change

What this lesson shows

A book costs $13 and Ana pays with $20. Count up from 13 to 20: $7 change.

The worked example

The lesson works this one step by step: $13, paid with $20. Then your kid tries one like it on paper.

The steps

  1. Start at the cost
  2. Count up to what was paid
  3. The jumps are the change

Helping at home

Start at the cost and count up one dollar at a time to the bill that was paid. Count the jumps: that is the change.

If your kid gets stuck

Count up from the cost.
