Learn it first!
To teach the simplified ASL to As a Child of God in singing time, I must know the signs inside and out! So I go over the signs several times using this video so I know it VERY well. I also learn everything backwards (or I mirror what I see). That way when I teach it, the kids mirror me and they learn it correctly.
After I’ve learned the signs, I write myself notes. This way, if I get totally stuck in the middle of teaching, I have something to reference. My notes may not make sense to anyone but me because I am telling myself how to sign something. I like to write the word to be signed and a description (which necessarily isn’t the actual sign to that word). The word being sung and the description may not always match due to translation.
Start with the Chorus!
I like to teach the chorus first since it’s so repetitive and the little kids tend to pick up on it quickly. Then I work through each verse.
Once the actions are well learned, I’ll pull out my scarves and we’ll sign with the scarves. It always adds a fun dynamic to signing and reviewing!
