There’s a nice site in the Netherlands that teachers can use to get ideas for special classes. One of the themes is about gestures and sign language. Mind you, it’s for all children, not just deaf ones. There are great suggestions for each age group: 4-5 6-7 8-9 10-11. It is in Dutch. The author is Ben Verschuren. I tried to contact him at the publisher, but to no avail. If anyone could introduce us, I’d be grateful. The one I like best is for the oldest kids, who are invited to study gestures in art. I just recently started doing that, and I’m age 33. God, I wish my teacher had read this website when I was young.
