So,I became a scratch tutor,though,when I lesson plan I don't know where to find projects for my lessons! Scratch On!

I don't understand… have you made your projects and shared them?

For Ressources for teachers and tutors who work with Scratch, see http://scratched.media.mit.edu/
For Projects on the Scratch Website, that are helpful, take a look around at “Explore”, you can also use search by tags like “helpful”, “tutorial” or anything else that interests you.
