I'd like to share something about sign language for primary. I live in England and all we have officially from church is a simple dictionary of church signs. There is nothing for primary, unfortunately, but hopefully one day, they'll get around to it. We have a lovely deaf girl in our ward, who has started coming out of her shell since we turned singing time into "sing and sign time". We now learn to sign more than half of all our songs, and to be honest the kids struggle when I teach them a song that isn't signed. I have made a poster of British Signs for the song "I pray in faith" (page 14 in the children's songbook). The purpose of this is to help the children develop the skills to sign a prayer.
