When I was in elementary school there was a girl in my class who was a hearing child of two deaf parents. For every single concert we learned the signs to go with the songs we sang. She got to teach them to us which was really cool! I still remember the entire alphabet and a few words. It’s an excellent learning opportunity, not only to teach kids a few words in sign language, but to educate them about people who have differing abilities and how to create a community that is welcoming and inclusive.
