How to play Number Line Jump
A number line stretches across the screen with your character on it. Read the jump instruction (skip counting by 2s, 5s, or 10s, or landing on a specific target number) and jump left and right along the line to land on the right spot. Wrong jumps show the right answer so mistakes become quick lessons in ordering and place value.
- Choose Start Adventure, which adapts as you play, or pick one of the four practice modes.
- Read the instruction, for example “Start at 15. Jump RIGHT by 5, 4 times.”
- Tap Jump Left or Jump Right. The counter under the question shows how many jumps you have made, so you never have to hold the count in your head.
- Press Submit when you have landed. Reset to Start puts you back at the beginning of the question at any time.
Difficulty levels
- Skip Counting (Grade 3) — Count on by 2s, 5s or 10s from a starting number. For example: Start at 15. Jump RIGHT by 5, 4 times.
- Negative Numbers (Grades 4-5) — Cross zero and land below it. For example: Start at 3. Jump LEFT 7 times.
- Fraction Jumps (Grades 4-5) — Move along the line in halves. For example: Start at 0. Jump RIGHT by ½, 4 times.
- Word Problems (Grade 5) — Read a real situation and model it on the line. For example: Temperature was 3°C. It dropped 8 degrees.
For parents
- The number line is the picture behind most of primary arithmetic. A child who can find −3 on it will find subtraction across zero far easier later.
- Untimed. If your child counts each jump out loud, let them — that is the skill, not a crutch.
- Negative Numbers and Word Problems are genuinely grade 4-5 work. Start with Skip Counting for a younger child.
In the classroom
- Eight questions per round, no timer, so pace is set by the student rather than the clock.
- The four practice modes let you assign one specific skill: send the Negative Numbers link during a unit on integers and the round stays on that mode.
- Share to Google Classroom or Copy link. Students play instantly, with no accounts.
School IT: no logins and no student data. Allow www.math-quest.org and hdainapfoxuamfrwritd.supabase.co. Full details for teachers and IT.
Questions about Number Line Jump
- What is Number Line Jump for?
- Building number sense on a number line: counting on, crossing zero into negative numbers, moving in halves, and modelling word problems. It maps to Common Core 3.NBT, 4.NBT and 5.NBT.
- Can I assign one specific skill?
- Yes. Pick one of the four practice modes before you share the link, and the round stays on that mode instead of adapting away from it.
- Is it timed?
- No. There is no clock. A round is 8 questions and a child can take as long as they like, including resetting a question and starting it again.
- My child keeps tapping past the answer. Is that a bug?
- It should not be. Every tap moves one jump, and the counter under the question shows how many you have made out of how many the question asks for. Reset to Start returns to the beginning of that question.
