Help! Suggestions for High Holidays Childcare Activities

I’ve been given a small budget ($50-$100) and a smaller staff (between 1 and 3 teenagers) and handed the responsibility for our childcare room during the High Holidays services. We’re expecting no more than 20 children at a maximum, likely closer to 8-10 will be present on a consistent basis. Based on previous years, the age range we’re looking at is likely about 3-8 or thereabouts.

Conservative shul, leaning conservadox — I’m trying to put together some activities which are seasonally thematic, don’t violate work restrictions, and relatively quiet as the childcare room is in the same building as the main services and the soundproofing isn’t amazing. We have a reasonable array of books for both group and individual reading and some toys.

Here is where I’m currently leaning:

1) Puzzles, leaving aside a couple pieces so they aren’t “finished” during the activity.

2) Making sukkah decorations using air dry clay. I’d take them home after yontif and spray them with sealant, so they wouldn’t technically be finished on the chagim either

3) Charades? Only concern here is maybe both volume and the age of the kids we’re dealing with

4) Asking the congregation for board game donations? Last year I was handed responsibility for childcare spontaneously when I arrrived at services (scheduled childcare backed out and I’m a Hebrew School teacher, it’s an occupational hazard) and we had some extremely ancient board games available to us, but they weren’t appropriate for young kids at all.

5) Decorating apple slices? Thinking of getting those little icing pens and cutting up apples like cookies for kids to decorate.

Here’s what won’t work:

1) Anything involving us going outside. Services are downtown in a busy area, so anything that invoves us going into nature is a no-go.

2) Songs, music, etc. Acoustics are not on our side here.

3) Anything we will need to order online from a speciality store as opposed to like, Amazon. Time and shipping is not on our side here. Ideally I would love to be able to just go to the dollar store for supplies outside of snacks.

4) Anything that requires a lot of reading. I will likely have a few kids who are early elementary school, but last year most of the attendees were pre-school.
