Prior Learning Topics

Click on the name of an activity in the list below to move directly to the **teacher video** and **TI-Nspire file download** for that activity - or simply scroll through the activities/teacher videos below the list. There is a very brief description for each activity, but the best way to gain some insight into the activity is to watch the teacher video. Although the 'type' of each TI-Nspire file is a *TI-Nspire CAS Teacher Software Document*, it will run on both the CAS and non-CAS version of the handheld device or computer software. If you wish to download all nine of the TI-Nspire activities relevant for the **Prior Learning Topics** for Math SL & HL in one zipped file, you can do that by clicking here.
