Instructions

1. Click a shape from the palette to drop it onto the grid.
2. Drag it to move, spin it with the curved arrow, or delete it if you want to start fresh.
3. Use the inspector panel to change lengths, angles, radius, or number of sides.
4. Watch the live perimeter and area numbers update every time you tweak something.
5. Duplicate shapes, recolor them, and build creative designs or math models.

Learning Notes

Shape Space turns geometry into a playground.

• Changing one side changes the measurements, so you can see formulas come alive.
• Rotating and sliding shapes models transformations.
• Layering shapes helps you design composite figures to measure.

Try recreating something from your classroom (a poster, a table, a robotics mat) and compare the digital measurements to real life.
