Number Line Jump

Choose a mode

Set the jump size with − / +, then press → Forward or ← Back to hop the car along the track. You can hop several times until you land exactly on the flag. Then press Check

Number Line Jump

Number Line Jump puts a car on a race track number line and asks students to hop it to a target position using jumps of their chosen size. Each forward or backward hop is a visible addition or subtraction, turning the abstract operation into a physical journey along a scaled line.

What students practice

Number Line Jump builds flexible mental arithmetic by making addition and subtraction directional: forward for adding, backward for subtracting. Students develop number-line intuition — the sense of distance and direction — which underpins integer operations and later coordinate work.

  1. Read the target number shown by the flag on the track.
  2. Set the jump size using −/+ buttons.
  3. Press Forward or Back to hop the car that many spaces at a time.
  4. Land exactly on the flag, then press Check to finish the round.

How to use it at home or in class

To reach 17 from 0 with jumps of 5: three hops forward land on 15, then switch to a jump of 2 for one more hop to reach 17. Students see 5+5+5+2=17 as a path, not an abstract sum.

Students often choose a jump size that does not divide evenly into the target and overshoot, then struggle to backtrack. The game allows mixed jump sizes in one round, encouraging students to plan a two-step approach rather than a single repeated hop.

Use it for individual practice, paired work, or a short class demonstration before worksheets.

Start with the game above, then continue with written practice to reinforce the skill.

Common questions

How does Number Line Jump differ from Skip Count Race?
Skip Count Race fixes the jump size (2s, 5s, or 10s) and asks students to mark every landing, practising regular intervals. Number Line Jump lets the student choose any jump size and make multiple hops of different sizes to reach a single target — it is more open-ended and covers addition and subtraction together.
Which grades is Number Line Jump for?
Grades 1–4, with simpler targets and larger jumps for younger students and two-digit targets requiring mixed jump sizes for older students.
Can the car go backwards to practise subtraction?
Yes. Pressing the Back button hops the car left along the track, modelling subtraction. Students may need to overshoot a target and hop back to reach it exactly.
