Interactive math lessons can be assigned to classes. Lessons have several activities and take between 15 and 30 minutes to complete depending on the activity and the class.
Newest: Symmetry, dynamic rotation designs
To do a lesson, click the link and go ahead. To assign a lesson to a class, click the ‘google classroom’ or the ‘geogebra classroom’ button at the top right on the activity and follow the instructions. You will be able to see your students complete the task in real time on your own screen.
To add/remove components of an activity, click the three dots and select ‘copy activity’.
