Progressive Ruling Rulers
In the downloadable manual you will receive a copy of the Progressive Ruling rulers that can be copied on paper if you want disposable ones or on card stock if you want them more durable. You might laminate them if you want to reuse them every year. A copy of the rulers can be made on transparency for overhead projectors. The rulers can also be scanned into an electronic chalkboard.
The students should cut out the rulers to separate them. This hands-on activity allows the students to study the rulers as they are cutting.
If you would like to receive a turn key product with printed manual, exercises, overheads, and professionallly printed sets of rulers see www.phoebe-ellen.com. Several packages are available.
