Here is why I value this show. When I was young I was hard of hearing and wore hearing aids. Luckily for me I can hear well enough to "fit in" with the hearing folks. I was in a class for deaf and hard of hearing kids. I was the only one in that class who didn't know sign language and I wasn't taught since I could talk well enough to be understood(that depends on who you ask, trust me). I wanted to learn but our teacher was too overworked and didn't have the time. I wish a show like Signing Time had existed back then.
The program is very simple, there is no stupidity or annoying jokes. It does have a frog called Hopkins, which is a cartoon frog. There is singing and lots of signing. None of the songs annoyed me, they are sung by Rachel and she incorporates the signs/words we learn throughout the program into the song. Words I learned to sign while watching the show that I can still recall at the moment are: Year, wind, snow, chilly, play, warm. The episodes I viewed were themed and dealt with weather and seasons.
I wish this show would have been around thirty years ago, then perhaps I could have enjoyed a conversation with my classmates. I would recommend this series for families and friends of children who are deaf or communicate through sign language and especially for students who have a deaf classmate.
