The PI Wheel is the perfect present for a great teacher. And a great gift for a perfect student. The PI Wheel consists of a tin can, magnetic diameter bars and a sturdy box for safe transportation. It comes in three sizes, 4 inch can, 9 7/8 inch can and a 48 inch diameter table. Special sizes can be ordered. The 4 inch can is shown below.
The PI Wheel has 360 degrees marked on it. And tabs are provided showing where the diameter bars can be placed around the circumference.

 Invented by Gerald Bauldock - Patent # 10/707,088

The PI Wheel is a device to help teach the equations and concepts for the circumference of a circle. It increases the level of learning to a higher level as described in Bloom's Taxonomy. Most people learn at the first level of learning by just remember facts. For example, a person might have remembered that   π = 3.14. But they might not be able to answer why π = 3.14. The second level of learning is understanding concepts. The PI Wheel shows that you can place three diameter bars plus a .14 diameter bar around the circumference of a circle. You can physically see this occurring and understand the concept of π. And this brings the students to a higher level of learning.

 

 
Also, use the tin can to store little knick-knack like staples, thumbtacks paper clips, etc.
The diameter bars are magnetized for easy placement around the circumference of the can. You can also store them in the can.

The PI Wheel comes in a nice sturdy box perfect for mailing to a friend across country or for wrapping as a gift.
