### student activities on the TI-Nspire: 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.
