How I Use It
It can be used a math practice/memorization tool since there are videos for all the addition, subtraction, multiplication, and division. I however am a huge fan of their number sense, algebra, and statistics songs. These are the most memorable ways I have found to teach order of operations, geometric measurement, and statistical terms (mean, median, mode, and range). Students get the songs stuck in their head as well as the concepts the songs introduce. The are fun and powerful tool for the retention of mathematical information.
The math concepts videos would be awesome enough on their own, but the built in lessons, worksheets, and quizzes put it over the top. The fact that the videos can be slowed with subtitles help to make them accessible to ELL and special education students.
