Linear Equation Games: Activity #7 Blackblobs
This is the Nspire version of the old DOS program 'Green Globs'. Students are given random points in which to find their own equations. The more points they go through with one line, the better their score.https://education.ti.com/en/activity/detail/linear-equation-games-activity-7-blackblobs
Unit Circle template
This is a one page unit circle template that you can copy and paste into a document that you are creating. To make it fit the screen, change the document settings to "float 3," and I used degrees instead of radians for all of the angles up to 180 degrees. You will also want to view in "handheld...https://education.ti.com/en/activity/detail/unit-circle-template
