How can I assign specific games to students if I’m using Canvas/Clever/Moodle/Blackboard/Edmodo/Schoology/any other LMS?

Collisions is not intended to formally assign a game to students. Rather, as a teacher, you would simply communicate to the students which Collisions games/levels that you want them to complete. Once students begin work in the specified Collisions game, you will be able to monitor student progress in that particular game within the Teacher Portal.  You can communicate the “assignment” information to students in a variety of ways, such as

  • verbal instruction;
  • writing the assignment on the classroom board;
  • posting an ‘Assignment’ in a Learning Management System (LMS) such as Canvas, Blackboard, Schoology, Moodle, etc.

If you are posting the assignment within an LMS, it might be helpful to include a link to Collisions in that assignment for students to click on. We recommend that the general link for Collisions ( be posted in a ‘Frequently Used Links’ section for students, and then “assign” the games in your wording. For example: “Homework: Please complete tutorial Levels 1-5 in Collisions game ‘Atoms’ by tonight; be ready to discuss, and work through additional levels with the class tomorrow.”
