Common Sense Media, a leading nonprofit organization that provides trustworthy information for kids and families to thrive in the world of media and technology, has produced Graphite, a great website for teachers  to discover, use, and share tools, apps, games, website, and digital curricula for their students. All resources are rated and reviewed by their trustworthy community of teachers. As a user, you can also suggest a product for review to get an honest professional advice from Graphite’s teacher community.
Graphite is useful for teachers to explore more in depth the worthiness of a tool or website and possible ways they might be used in the classroom. Graphite is still in its first year of launch but has great potentials to grow its stock of reviews.
