How I Use It
I currently use Learn Zillion to supplement Math instruction in my classroom. The instructional videos are very concise and the visuals can often give students yet another way to grasp some of the more concrete concepts in Math. The videos are a very manageable and appropriate length, and I like being able to search for lessons and videos by standard. I don't often play the videos all the way through. I will pause at certain points to interject or check for understanding. In fact, many of the videos are structured so that the teacher will do just that.
I consider this website an excellent resource for instruction. The lessons are well thought-out and I consider them a quality resource for supplementation. Although the lesson and videos are of high quality, I recommend screening ahead of time so that you'll be prepared to enhance with your own teaching and be able to judge where feedback and checking for understanding would be appropriate. This is not a case of simply sitting back and letting a website teach a lesson for you!
