The videos included in the Video Spotlight earned high marks in at least one of the Math Video Challenge content areas (mathematical content, communications, creativity, real-world scenario). We hope they provide useful examples as your team begins to produce a video. But please note, inclusion in the Video Spotlight does not mean a video is perfect. A creative video may have a math error. A video with a fantastic solution may have a weak real-world scenario. It's important to pay attention to which content area each highlighted video excelled in as you look through this Video Spotlight.
