Khan Academy from Microsoft allows you to integrate a preview set of the free videos and exercises from KhanAcademy.org into your Office Mix lesson.
With the app you can browse and search through Khan Academy videos and exercises to find the perfect piece of content to integrate into your online lesson. The video library covers math, science topics such as biology, chemistry, and physics, and even subjects like finance and history. Exercises allow your students to practice at their own pace. Each problem is randomly generated, so you never run out of practice material. If you need a hint, every single problem can be broken down, step-by-step, with one click. If you need more help, you can always watch a related video.
