many features that students and teachers often overlook. That's bound to happen with any program that has been around as long as PowerPoint has and includes as many features as PowerPoint does. One of those overlooked features is found in the Add-ins available for PowerPoint. Browse through the gallery of Add-ins and you'll find some excellent tools for math teachers and students.
The GeoGebra PowerPoint Add-in lets you access GeoGebra materials directly from your PowerPoint slides. You can also use the Add-in to create graphs, shapes, and spreadsheets within your slides. The GeoGebra PowerPoint Add-in works in the desktop and online versions of PowerPoint.
Khan Academy's math videos and math practice exercises are available in a PowerPoint Add-in. The Khan Academy PowerPoint Add-in lets you find videos and exercises to insert directly into slides. The exercises that you insert into your slides are fully functional which means that you could use them for live demonstrations without having to leave your slides.
PhET provides free interactive math and science simulations covering topics in physics, chemistry, biology, earth science, and mathematics. In the PhET library you'll find simulations appropriate for elementary, middle, high school, and university students. More than 50 of the PhET simulations are available to insert into PowerPoint presentations through the use of PhET's free PowerPoint Add-in. With the Add-in installed you can browse the available simulations and insert them into your slides. The simulations work in your slide just as they do on the PhET website.
