This is the children at Rancho Sordo Mudo during their graduation. They signed a song in (mostly) Mexican Sign Language.
Although they are taught a sort of American Sign Language (ASL) with a Spanish twist, they are now beginning to start to teach them Mexican Sign Language (LSM). But the trouble is that the volunteers at the school are mostly American. The school resources and signing resources are mostly for ASL so it is difficult to find volunteers capable to teach them sign in LSM.
But it is changing, slowly, but surely. Because the signs are different - with similarity's sure, but different nonetheless.
Still, we (and they) are grateful to learn ANY type of sign to communicate and then learn the 3 R's and finally but most importantly . . . about Jesus. That sign is the same in LSM or ASL.
