About Number Line Jump

Number Line Jump builds number sense. A kangaroo wants to land on a number, but many of the marks on the line are blank. Use the numbers you can see to work out where the target goes, tap the spot and watch the kangaroo bounce there. Lines go 0–10, 0–20 or 0–100 in tens.

How to play

1. Read the number at the top.
2. Find the labelled marks near it and count along.
3. Tap the mark where it belongs.

Tips

Halfway between 0 and 10 is 5 — use the middle mark as a landmark.
