Students get to choose which projects to complete ranging from a character sketch to a speech to a research poster. You get to pick the total number of points they must work toward.
There are 3 activities worth 10 points, 3 worth 20 points, 3 worth 30 points, and 3 worth 40 points. I usually make the requirement between 50 and 60 points. If students want to do two more challenging projects totaling the required points, they may do so. If students want to do four easier assignments, they may do so. This lends itself well to all levels of workers.
Rubric to help with grading is included.
