Arrows at both ends

Addition and subtraction jumps

Starting value for jumps

Jump sizes (+ forward, - backward)

Enter signed jumps separated by commas or new lines, such as +5, -3. Write +1/4 * 4 for four equal jumps. Fractions and mixed numbers work too. Up to 12 nonzero jumps. This repeats addition; it does not solve expressions.

Hide jump results and worked answers

Points / Intervals / inequalities

Points

One point per line, such as 3/4 | A. The label is optional. Up to 20 points.

Intervals / inequalities

Examples: [1/2, 3/2), x >= 3, -2 < x <= 4. Use one line per interval, or OR for a union. Write -inf or inf for rays, as in (-inf, 2]. Enter solved inequalities; the tool does not solve 2x + 1 < 5.

Student version / Answer key

Hide selected tick labels

Separate tick values with commas, such as 3, 7, 11. Points and shaded intervals stay visible.

Input guide & saved settings

Enter integers, decimals (0.5), fractions (1/4) or mixed numbers (-1 1/2). Up to six decimal places, from -1,000,000 to 1,000,000.

Type decimals with a period. Use commas to separate jumps and hidden tick values.

How to read this number line

A filled circle includes the endpoint; an open circle excludes it. An arrow on a shaded interval means it continues past the visible range.

Ticks follow your exact interval. If the end value is not a tick, it stays as the edge of the view. Scroll the preview if it is wide. Rounded decimal labels show ≈; fraction labels are exact.

What you can make

What can you make with this number line generator?

A number line shows how numbers compare and how addition and subtraction move along a scale. Equal gaps mean equal differences, whether you are working with negatives, decimals or fractions.

This generator draws number lines with evenly spaced ticks, marked points and shaded intervals. Set the range and an exact tick interval, add addition and subtraction jumps, or hide labels to turn the line into a student exercise with an answer key. It works with integers, negatives, decimals, fractions and mixed numbers.

Range

Choose the first and last values students will see.

Tick interval

Use 1, 0.1, 1/4 or any exact positive spacing.

Points and intervals

Mark single values, bounded intervals and rays such as x ≥ 3.

Practice and export

Hide tick labels, then download the worksheet and answer key.

What the generator does

Fraction scales, inequality graphs and addition jumps

What you see in the preview is exactly what you download.

Plot fractions, decimals and mixed numbers

Type 1/4 or -1 1/2 directly. Fraction labels are reduced automatically, and switching between decimals, fractions and mixed numbers never moves a point.

Try the generator

Number line with quarter-step ticks and a point at 3/4.

Graph points and inequality intervals

Shade a solved inequality such as x ≥ 3, or type interval notation. Open circles exclude an endpoint and filled circles include it. Put several intervals on separate lines to show a union.

Try the generator

Number line with an open circle at -2, a filled circle at 4 and the segment between them shaded.

Make blank worksheets and answer keys

Hide every tick label for a blank line, or only some for fill-in practice. Points and intervals stay in place. Print one, two or four identical lines, and download a separate answer page with the numbers restored.

Try the generator

Two number lines with missing tick labels for student practice.

Show addition and subtraction as jumps

Pick a starting value and enter signed jumps, or write +1/4 * 4 for four equal jumps. Arrows show each direction, and the worked steps show where every jump lands. Hide the results for practice, then restore them in the answer view.

Try the generator

Built for exact math

Exact ticks, clear endpoints

Equal values land on the same point, and each endpoint symbol shows exactly which values belong to the set.

Exact tick placement

Ticks are calculated with exact fractions, so repeated steps like 1/3 never drift. If the end value is not a tick, it stays as the edge of the view.

Clear endpoint rules

Open circles exclude an endpoint and filled circles include it. Infinite ends are always open, and invalid interval notation blocks export.

Range warnings

A warning appears when a point or interval end falls outside the visible range. Hidden labels must match real ticks.

Frequently asked questions

Number line questions for lessons, worksheets and downloads

What can I download with the free Number Line Generator?+

SVG, PNG and PDF, including a two-page worksheet with its answer key. No account is needed and there is no watermark. Settings and export run in your browser, and you can save your settings as a file to reopen later.

How do I make a number line with fractions and decimals?+

Enter a tick interval such as 1/4 and choose Fractions or Mixed numbers. The start, end and points accept fractions, decimals and mixed numbers like -1 1/2. Equal values such as 1/2 and 0.5 share one position, and changing the label style never moves them.

How do I create a blank number line worksheet with an answer key?+

Turn on the blank version to hide all tick labels, or list specific ticks to hide for missing-number practice. Points and shaded intervals stay visible. Choose one, two or four identical lines, then download the worksheet + answer key PDF. Page one is for students, and page two restores the labels.

How do I graph inequalities and interval unions on a number line?+

Type a solved inequality like x >= 3, a chain like -2 < x <= 4, or interval notation like (-2, 4]. Put each on its own line, or join them with OR, to show a union. Open circles exclude endpoints and filled circles include them. Solve algebraic inequalities first; the tool graphs the solution set.

How do I create a vertical number line?+

Choose Vertical under Orientation. Values increase upward, and your range, ticks, points and intervals stay the same. Exports match the preview. Fractions, jumps, student worksheets and the answer view work in both orientations.

How do I insert a number line into Word or presentation slides?+

Download a PNG and insert it as an image. Use SVG if your app supports vector images, so it stays sharp when resized. Use PDF for printing; PDFs use A4 pages, so choose Fit to page when printing on Letter paper. If labels look crowded, increase the tick interval before exporting.

Why are some points, endpoints or jumps missing?+

Points and interval ends outside the visible range are cut off, and jumps that start or land outside it are not drawn. Check the warning, widen the range, or choose Fit range to jumps. The scale can show 2 to 61 ticks.

How do I show addition and subtraction jumps and hide the answers?+

Enter a starting value and signed jumps like +5, -3, or +1/4 * 4 for four equal fraction jumps (up to 12). Turn on Hide jump results and worked answers to leave blanks for students. The answer view restores them, and the worksheet + answer key PDF includes both.
