Using a kagan strategy, students work in their home groups to find the missing side of a missing right triangle using the pythagorean theorem. When they are finished, they use the symbol on top of their worksheet to form a new group in one of four corners to compare answers, discuss errors and get additional help if needed. They then return to their home group to correct errors and finish activity.
Included is 4 versions of a worksheet and 3 versions of an exit ticket to use as an assessment, or even a review at a later time. Answer keys are included for all.
