Each course consists of 4 modules. Each module is designed to take hours to complete. This includes about 20 minutes to watch the video, and the remaining time for online activities.
The activities are a mix of traditional mathematical problem solving, and online interaction. For example, in Archimedes and the Law of the Lever you will use mathematical concepts to balance a lever. On the more social side of things, you will brainstorm and post pictures of levers from your daily life (and you get to see what everyone else posted).
