Interactive Number Line Generator
Model whole numbers, fractions, decimals, or negative values with adaptive tick marks and prompt boxes. No sign-in required—just set your range and export a PDF.
Live Number Line Creator
Adjust the manipulative, then export a printable PDF or jump into the full editor.
Click any tick to cycle between showing the label, hiding the label, or removing the marker entirely. Drag the handles to reposition the number line or shrink the step size for more ticks.
Prompts anchor to specific ticks. Toggle them on to collect quick-write responses or exit ticket reflections under the line.
Why teachers love this tool
Flexible ranges
Set any combination of start and end values—from whole numbers to decimals—and the tool regenerates ticks automatically to keep spacing uniform.
Visibility controls
Toggle each tick between showing labels, hiding labels, or removing the marker entirely so you can scaffold number sense step by step.
Prompt-ready annotations
Enable prompt boxes aligned to specific ticks to ask quick-write questions, comparisons, or measurement reflections directly on the number line.
Classroom-ready use cases
Fraction comparisons
Model benchmark fractions or decimals, hide selected labels, and ask students to annotate equivalent values or explain their reasoning.
Elapsed time scenarios
Flip the number line to minutes or hours, insert prompts at start/end ticks, and let students show jumps that represent elapsed time problems.
Math workshop stations
Print differentiated lines for each group—integers for foundations, decimals for enrichment—while keeping a consistent layout that students recognize.
Frequently asked questions
Can I hide the start or end labels for a challenge?
Yes. Select any tick to cycle its visibility: show the marker with a value, show only the marker, or hide the marker entirely to create open-ended prompts.
Does the tool support negative numbers or decimals?
It does. Enter negative values or decimals for the start/end points and choose an appropriate step size. The generator keeps spacing proportional regardless of direction.
How can I add more context for students?
Use the prompt boxes to pose a question or give a starter sentence. You can also export the PDF and add additional directions inside the Checkfu editor if you need multi-step tasks.
