We're doing a "Frozen" Bible Study at our church sleepover this weekend.
This is the end-of-year blessing used at St. George's, Campden Hill, put together by Margaret. The children and Sunday School teachers, and the work done in Sunday School, are all honoured in sight of the congregation. It can easily be adapted for schools. The closing blessing is from Common Prayer: a liturgy for ordinary radicals, which you can purchase here.
