I started race 2 achieve unit that was provided free of charge by the National Guard. This is awesome because I chose the set for trigonometry and I am doing it with my students. The students are currently finishing up the cars so we can race them down the hall. We will do time trials and then work our way through the rest of the unit till we have modified the cars so they run better.
This is what the car looks like when finished. They are still working on operating them but they are working and helping each other to create the cars. So far this is great because they are all involved in it. If we don't run trials today, we will run them tomorrow. This is a great math project and fulfills STEM requirements.
