This tool displays heat maps of each student's activity on the site. Activity, for heat map tracking purposes, means any activity on codehs.com: typing, clicking around, moving the mouse, etc. A darker square indicates a day with more site activities. You can hover over a square to see the date and how many activities were completed on that date.

Free and Pro teachers can view the individual student heat maps by navigating to the Roster page of a class Section and selecting the Student Settings button.

Pro teachers can see the Activity Map for all of their students on one page. To view the Activity Map for your Section, navigate to your Toolbox > Activity Minimap.
