Every lesson is built for about 50 minutes and has the same parts: four slides before a demo, an interactive demo that runs in the browser, four slides after, a hands-on activity and a short discussion. Slides come in a light version for printing and a dark version for projecting. The instructor guide has talking points, answer keys and citations. The flash cards print double-sided.
The tools, products and projects named in the lessons are examples, not recommendations, and the guides say how to compare options. Lessons dated October 2026 name the facts they rely on, so check current documentation before you teach.
