In every class that I teach, students have the opportunity to earn 10 points per day. We spend time working in the shop or on projects and the bulk of a students grade can come from these participation points. If a student comes to class, goes to work and keeps busy the whole period, then they will earn all ten points for the day. Students also earn points for assignments and projects that they are assigned to work on. One of the ways for students to lose points is to use swear words.
In the shop, students need to bring their own supplies such as wood or metal. I can pick up supplies for the students, but they will need to pay for those supplies.
