Python notebooks are hosted on Google Colab, with no python installations necessary. Each notebook demonstrates some concept from the text, and are suitable for in-class demonstrations or out-of-class explorations.

Images and animations included in the text already, but several interesting relevant examples have not been included. These can still be used in classes for additional explanation or small deviations from the specific content in the text.

Interactive Doenet elements are included throughout this text, whether in the activities or in the exposition between student explorations. Source code for all of these interactive elements can be found on the Doenet website.
