Virtual graph paper
Square, dotted, isometric, polar or Cartesian, whichever the lesson needs. A projector-ready graph pad with seven paper styles, snap-to-grid drawing tools, plot-by-coordinate, undo/redo, and PNG export. Switch from coordinate planes to isometric to polar without breaking the flow of the lesson.

Features
What it does.
Seven paper styles in one click
Square, dotted, isometric, polar, Cartesian, ruled, and blank. Switch as the lesson moves from coordinates to vectors to net diagrams.Real drawing tools
Pencil, line, rectangle, ellipse, polygon, point, label, and eraser, with snap-to-grid, dashed strokes, and live coordinate readout.Plot by typed coordinate
Punch in (x, y) and the point lands in the right spot. Perfect for plotting solutions to equations, vertices, or the next step in a transformation.
Use cases
In the classroom.
- Plotting linear functions
- Drop the Cartesian grid, plot two solutions to y = 2x − 3, draw the line through them. Then change the slope and let the class predict where the new line will sit.
- Geometric transformations
- Draw the original triangle on a square grid, then rotate / reflect / translate it onto a new spot, the snap keeps the corners on integer points.
- Polar curves
- Switch to polar paper to sketch r = 1 + cos(θ) live. The coordinate readout shows r and θ, so the class watches a spiral take shape.
- Isometric drawing
- Engineering, architecture, and 3-D shape lessons. The 30° grid keeps cubes and prisms looking right without a ruler.
Try it with your class.
