Make coordinate mystery pictures
Draw or trace a picture on the grid and get the point list, a blank grid, the answer key and 3 difficulty versions. Version A is free to print, with no sign up, and your pictures stay in this browser.
Your saved pictures could not be read. Nothing was changed. The saved record is damaged, so it is left as it is and nothing can be changed here until it is replaced. If you saved a backup file, restore it.
Your saved pictures could not be read. Nothing was changed. This browser is not letting the page read its storage. Nothing can be changed until your pictures can be read, so they stay exactly as they were saved.
Opening your saved pictures.
Drag to draw; the line snaps to the grid. Keys: arrows move, Enter adds a point, Escape lifts the pen.
Shapes none yet
Each shape is one line the student draws without lifting the pen. Lift the pen to start the next shape.
Simplify pen lines
Applies to lines drawn with the pen. Aim for 20 to 120 points a shape.
Trace a picture
Load a PNG or JPG of up to 5 MB and draw over it with the snap grid. The image stays on this device.
Worksheets
Your worksheets appear here. Draw a picture on the grid, or start from a starter picture. Each version shows its point list, its preview and its downloads.
How the worksheet is made
Plain arithmetic on whole grid squares, so every point you see is a point the student can plot.
- Every point snaps to the grid. The pen keeps the grid points it crosses, then drops the ones that sit on a nearly straight line, so a shape has a sensible number of points.
- Three versions come from one drawing. Version A is the picture as drawn in the first quadrant. Version B moves it by whole squares to sit across the axes. Version C labels each square 0.5, 0.25 or a fraction.
- Nothing is rounded. A point that cannot sit on a grid line in a version is flagged by its number, and that version waits until you move it.
A worksheet needs at least 2 shapes or 10 points and holds up to 400. As a rough guide, 150 points fill a 45 minute lesson. Every rule is on how it works, the 24 starter pictures are ready to open, the free printables need nothing filled in, and the guides cover running the lesson, choosing a point count and using the 3 versions.
