I want to share what we did with a theme and names for our Sunday school once we started using a rotation model last July.
We don't have a particular name for our Sunday school other than "Sunday School" but our theme is "Growing People of Faith." It's a gardening theme.
We use rooms in our church that are not dedicated to the education program; many community groups and other church groups use them. Also, we have different workshops in each space depending on logistics, etc. So we have given the rooms/spaces names which we post on doors, etc. We have the Garden Patch and the Greenhouse. We have an Orchard and an Arbor. We have a tool shed (utility closet) and the Potting Shed (a space near the kitchen.) The Orchard is a room with a door and the TV/DVD capabilities. We tend to have movies in there or music, which tends to be louder. Sometimes Drama is in there depending on how the other spaces are being used. Our regular classroom is the Garden Patch and is where any number of workshops take place. Because the Garden Patch and Greenhouse (2 halves of the classroom which has a divider) have carpet anything messy is done out in the Arbor or Potting Shed. The latter are the areas we've designated in our Fellowship Hall.
Our classes are known by names rather than grades. This is both fun but also helps when students may need to be in a class other than the one that's their grade: a less mature student can go into the younger group or vice versa.
Our "Seedlings" are in the "Nursery".
Our "Sprouts" are K-2nd grade this year.
"Saplings" are 3rd-6th grade.
"Buds and Blooms" are Jr and Sr. High students.
The students all have aprons with their name tags on them which are different depending on their group. The Sprouts have green ones, the Saplings have gold. The Buds/Blooms have either a waist apron or a gardening hat. The aprons are used to keep clothes clean, show the name tags and collect pins for each completed rotation. The teachers are called "Gardeners" and they wear a yellow gardening apron upon which I put a picture of geraniums growing in little pots. We also have "Wheelbarrows" (who wear an apron with a wheelbarrow on it) who take the Sprouts, Saplings or Buds/Blooms from workshop to workshop. It's taken a while for folks to catch on to the names "Gardener" and "Wheelbarrow" but after nearly a year they seem to have gotten used to it.
The Sprouts and Saplings love their names and aprons, etc. The older kids aren't so keen on their hats but they do attach their pins to them with some pride.
In each space we have different workshops each month and these workshops are simply called "Music", "Science", "Carpentry", etc.
This took a while to figure out, given our space limitations, but we are loving it.
