This is an example of a teacher that used Claymation in her classroom. It does not give great detail about how she did what she did, however it does discuss how it was beneficial to her students.
I discovered this site through a blog another teacher posted onto after he used animation in his classroom. It is a data base of sound effects that you can download onto your computer. If you do not have access to garage band this may be a great place to get a hold of some sound effects.
I thought this website was interesting. It uses animation and games to engage the students. It also has a few lessons of how they suggest using animation in the classroom.
