Circle Time is a really worthwhile and popular weekly event in the classroom. Builds personal self esteem, classroom spirit, provides a forum to discuss 'issues' and is a safe venue for students to express feelings and opinions. And the kids love the games!!
...the Circle Time resources to be found at Inyahead Press. http://www.inyahead.com.au/
They've got good books for Circle Time set up and use. I love the cards! Apparently they run inservices too.
