This collection of digitally interactive Open Middle exercises was developed by Tim Brzezinski and he is adding more all the time. The collection already has over 150 activities from Open Middle made interactive for students to explore.

The activities are compatible with Google Classroom and can be easy embedded and assigned to your class, though they can also be shared with students via link.

All of the problems are based on the engaging problems found on Open Middle. To read more about how to use Open Middle with adult education students, check out Hundreds of Challenging Math Problems Worth Solving.
