Scholastic has created a site called StudyJams!, full of over 200 short, upbeat educational videos on math & science topics. The videos are organized by topic, so you can just find the video that matches the educational concept you're covering in class!
Study Jams is a Scholastic website designed to help elementary school students learn and review math and science information through songs and videos. To use Study Jams students search for a topic in the math or science category. Each Study Jam offers a short tutorial on that topic in the form of a video, slideshow, or song. When there is a song available Study Jams provides a karaoke format for kids to sing along if they like.
