How I Use It
I would have students watch the video, then complete the quizzes. They would email the results to me. They would then complete the activities and play the games afterwards. I use this in many subjects, such as language, math, health, science etc. If I didn't have access to a lab, I would show the videos on a projector, and have the quizzes and activities printed out for them to complete.
This site has a number of really great videos for students to watch, and then gives them quizzes, activities, games and more for them to do based on what they've just learned. The videos are a very high quality and they tasks are challenging. Worth the subscription.
