What are number line jumps?

Each problem, like 7 + 4, comes with a number line. Children start at the green dot, draw one jump for each one they add or take away, and write where they land.

Which ranges are there?

0 to 10, up to 20, and tens up to 100.

Are answer keys included?

Yes. The key draws the jumps and the answer.

Seeing addition and subtraction

A number line shows adding as moving forward and taking away as moving back. It is the bridge from counting objects to mental maths.

In the MATATAG curriculum

Grade 1Addition as counting up, with sums up to 20.
Grade 2Adding a 2-digit and a 1-digit number by counting up on a number line.
Grade 2Subtracting on a number line, as the inverse of addition.

The MATATAG guide names the number line as a Grade 2 tool for adding and subtracting, so the jump sheets to 20 work for late Grade 1 and early Grade 2, and the tens-to-100 lines for Grade 2.

Fractions go on the number line from Grade 2 too, ordering similar fractions. This maker uses whole numbers only, so use fraction strips for that part.
