WatchKnow is a non-profit site which means that there aren't any charges. It offers you the opportunity to individualize your assignments without cost and add depth to lessons for those students who learn quickly, need remediation or benefit from visual presentations.

The search engine has a couple of unique features as well. You can search by subject and by age level. No need to spend time wading through a bunch of so-so videos or those that aren't useful to your grade level. Teachers are adding videos daily so you may want to check back as your curriculum progresses.
