During the semester I spent in grad school, I had a job as a Music Specialist at a nearby synagogue.
Every Sunday, I'd be sent to a different Hebrew classroom for forty minutes to teach a song to that week's class. Then, after a short break, I'd return to my classroom, where I'd have another group of kids for an hour. This second class contained the same kids each week -- kids the Rabbi and Cantor had decided could not be integrated into the "regular" Hebrew school classroom because of emotional and/or behavioral challenges.
The synagogue had primarily hired me to babysit this second group of kids whom the clergy didn't want to work with. My job was to keep them occupied, ideally with music, but I could do almost anything if it had Jewish content. (The synagogue set a pretty low bar for me, and frankly for the kids too, which was a shame.)
When it came time to talk about the High Holy Days, I wanted to teach the kids about the shofar. The synagogue had no shofarot, not even cheap plastic imitations, for me to work with. So, thinking on my feet, I came up with the idea of the Pocket Shofar. The kids loved it (phew!) and I have used it in every religious school setting I've worked in ever since.
So here's a little something you can have fun. It works with almost any age group (preschoolers have ridiculous fun with it, but so do parents). Try it and see for yourself!
Special thanks to Hadar for the nudge.
