How I Use It
I have used this website to find videos that simplify difficult or very abstract topics. Not all videos are great. Some are outdated. The ones I've really liked repeat the concept in many different animated and sometimes silly way but allow the concept to sink in due to different approaches as well as simple ways to remember the ideas.
It is a good support; provides simplified ways to explain tough concepts. It can be shared with students and repeated several times with or without sound, paused as needed, while students fill in or anticipate what comes next. Useful also for students not performing at grade level.
