The Calliper tool is a great for use when trying to draw things to scale. This tool, used in conjunction with the Grid function, can be used to create very accurate drawings.

Step 1 - Use the Polygon tool to draw a graphic.

Step 2 - Click on the Calliper tool button on the Math Draw Toolbar.

Step 3 - Click on one on end of the shape and then drag your mouse to the other end and click again.

An interesting lesson idea would be to have your students draw a graphic and then estimate how long they think the sides are. Then add the grid to the page and have the students revise their estimates. Finally, let the students use the Calliper tool to see what the actual measurements are.
