3rd grade math · Unit 1: Multiplication and division

Equal jumps on a number line

What this lesson shows

8 jumps of 6 land on 48.

The worked example

The lesson works this one step by step: 8 × 6. Then your kid tries one like it on paper.

The steps

  1. Start at 0
  2. Jump the same each time
  3. Count the jumps
  4. The last landing is the answer

Helping at home

The first number says how many jumps, the second how long each jump is. Start at 0, jump the same length each time, and say each landing aloud. The last landing is the answer.

If your kid gets stuck

Start at 0. How long is each jump?
