About Number Line Jumper

The number line is one of the most powerful tools in early math — it makes counting, place value, and even negative numbers visual. Number Line Jumper turns that classroom tool into a game your child can play in 90 seconds.

Three task types

• Find: "Tap 7" — place the jumper on the right tick.
• Missing: one tick is blanked. Pick the missing number.
• Skip-count: start at a number and tap the next jump (e.g. start at 4, jump to 4 + 2).

Ranges

Levels scale from 0–10 up to 0–1000 (in jumps of 100), and include a negatives level (−10 to 10) to introduce integers gently.

Recommended for

Ages 5–9. Aligns with K–3 expectations around counting, place value, skip counting, and an introduction to negative numbers.
