The lesson plan that she utilizes is specifically for grades 3-7 mathematics, but I think that I would be able to utilize this in a high school classroom as well. The lesson teaches the students the concept of speed. The lesson plan includes cooperative learning through a group activity of two students. Students will ultimately come together as a group and introduce their Tinkertoy Derby Cars to the class and have a race! I feel this project will bring individuals together to work as a team. Below is the lesson plan itself, but in addition I found another plan that can be used if you do not have the Tinkertoy's available for use in your own classroom.
