You can probably find a school via epals.com I have done simple projects this was in the past.
I teach art in a public elementary school (K-5) in the United States. I'm looking for a classroom in Italy or Greece that is interested in working on a collaborative project that involves visual art, music and writing. Any international teachers interested in this project, or anyone with a connection to an international school? The school we collaborate with would need access to the internet.
