My name is Jim Olsen. I'm a retired teacher - regular and special ed. I’ve worked with students of all ages. For years I've wanted to share, beyond my workshops, some of the ideas I've come across or developed. So here goes! Most of these thoughts are lower-tech or older-tech. If you like at least one or two of these ideas, and want to use them, I'm pleased! Please let me know!
If you want more information about something, feel free to email me.

If you know the diameter of the circle on the ground or building, what is the distance to the hole
in a tree that is projecting it? How do we know?
Email me about that or with questions or comments or for more information at olsenjim@yahoo.com.
