Common Sense Media created Graphite to make it easier for educators to find the best apps, games, and websites for the classroom. Each app is searchable by: type, subject, age, and price. There is an expert rating and aggregated teacher rating. Each app is rated for engagement, pedagogy, and support. They include pros, cons, and bottom line, their review, how it works, and field notes (how to use it in the classroom).
They've thought of everything a teacher (or parent) would want to know. The site is very easy to navigate and use.You'll find a great introduction video at the top of their home page.
