Choose the tool for the question.

Use a number line for values on one axis. Move to a coordinate plane when every point needs both X and Y. The slope tool connects two points to a straight-line equation; the quadratic tool connects three coefficients to a curved graph. Transformations show how one rule moves every vertex of a shape.

For a lesson or for independent practice

Explore mode shows the calculation alongside the diagram. Practice mode hides the completed result so a learner can work on paper and reveal it when ready. Download the question page alone or include an answer key. The tools do not grade responses or claim alignment with a specific curriculum.

Ready-made sheets when you do not need to customize

Each tool page includes original A4 and US Letter PDFs that work without JavaScript. Use the SVG diagrams in a document or slide, or download the example values as CSV. Customized inputs stay in your browser. Worksheet PDFs use high-resolution images; SVG diagrams remain vector.

For experimental observations, survey results or category comparisons, use the statistical chart makers. For personal routines, try the printable habit tracker.
