Reading Bear is aimed for children learning to read from ages 4-7.
It is a free website that anyone can use in conjunction with a class lesson or on its own. This site combines text and audio with pictures and videos to help students sound out words and view what each word means.
These lessons allow students to interact with lessons and lessons have videos to support it. If you only wish to view the videos, WatchKnowLearn has them available for anyone to view on their site. To link to the videos only: http://www.watchknowlearn.org/default.aspx
This is an introductory video that demonstrates how the program works.
