I'm in the UK, so don't know how things are in the US, but if the kindergarten is in an impoverished needy area and there is a good financial reason why the school can't offer more funds itself for materials, has she (or the school) thought of approaching companies and businesses who might help ? As a for instance, here in the UK Barclay's Bank provide funds for weekly drama sessions for physically and learning -disabled adults in our town, they sponsor the costs for costume and scenery for the annual show in the local theatre and some of the staff work with the group as volunteer helpers. I believe the bank does this as part of their nationwide community assistance programme. I'd be surprised if there weren't similar schemes in the USA. It's certainly an avenue to pursue, I would think.

All good wishes,
