Three Rivers Homeschool Co-op

03/22/2026

We're welcoming visitors with teens this Wednesday.

If you have teenagers as well as a younger sibling, that's okay...but our younger group is pretty full, so we aren't in a position to welcome families who don't yet have a teenager... sorry about that.

If you think you'll make it, please send an email to me (Ali) at [email protected] and I'll include you when I send out sign-ups for the one-day classes we're offering.

Our next visitor day will be in the fall, when we devote half the day to ice breakers. This Wednesday doesn't have the same visitor-specific programming, but you are nonetheless very welcome to come and see what you think. :)

Here's a rough outline of the day:

What: Three Rivers Homeschool Co-op
Where: Marbletown Town Park on Tongore Road
When: 11 a.m. - 1:15 p.m., ish, and beyond
Cost to visit: Free (our co-op costs about $20 per year, per family)

11 a.m.: Arrive and mingle (who doesn't like a good mingle, lol?)
11:15 a.m.-12 p.m.: Class
Noon-12:30: LUNCH (B.Y.O.)
12:35-1:15 p.m.: Class
1:15 until ?: Goof-off time

Once I have the class schedule for Wednesday, I'll send it out via email. If you have questions in the meantime, feel free to ask. :)

Thanks!

Money:
Families pay $10-ish per session, and with about 4 sessions per year, that comes to around $40-ish per family, per year. We are required to pay for insurance to be allowed to use the Marbletown Community Center and other town facilities, and the dues pay for that annual insurance and other town fees.

General Information:
We are not a drop-off and we don't hire people. Instead, we pool our talents. We take turns teaching classes, we all pitch in with set-up and clean-up, and we try to take good care of the town's property (No, you do not need to wear a party hat. Yes, you do need to refrain from climbing on the furniture, even if "furniture" is just a picnic table. If you join our co-op, you'll get to enjoy reading the participation info in full.)

Session runs for five-ish weeks and often end with an end-of-session open mic, potluck and swaps day (the kids bring things to 'sell' and 'buy' with pretend co-op money).

We also sometimes meet in the evening - we've had a couple art shows, a few theater performances, several dances, two graduations...

Activities:

Soccer/Frisbee Football Tournament (2nd annual, with changes)

FAQs

Q:
So the activities will occur in the order listed?
A:
Almost certainly not. They are all fairly high-maintenance, weather-requirement-wise, so they'll happen whenever the weather is right (if applicable). It's an emotional roller-coaster.

Q:
Last year, for the ice carving, my ice block wasn't fully frozen. When I started chipping, almost-frozen water ran out and froze my fingers.
A:
I'm so glad you brought this up! If you have large plastic recycling, or a kitchen-size plastic garbage can, please put it out NOW with about 12" of water in it, so it has its best chance to fully freeze.

Q:
Bathrooms? Will there be bathrooms? With liquid soap and warm, running water?
A:
No. But if you lower your standards, yes! We'll have a port-o-potty. Yay! Port-o-potty! And hand sanitizer!!

Q:
Will there be hot cocoa and tea and stuff? And cookies? And free money?
A:
Unknown. Ideally, I may try to bring more lumpy cocoa, and possibly hot water, and possibly tea bags, but I might not, and it will probably be B.Y.O. mugs this year

About us:
We meet weekly on Wednesdays in Marbletown, from roughly 11 a.m. until 2 p.m. We don't hire people, so we create, organize, and run all our own stuff. Parents take turns teaching, cleaning, organizing, you name it. We charge $10-ish per session ($40 per hyear) to cover our insurance. Other than that, we try to use whatever we have in our own closets/kitchens/attics.

Winter Session:
In a couple of weeks, we'll be moving back outside for our "winter session," which will be:
1) cold, on account of we'll be outside, and
2) different, on account of we'll be outside
Potential activities include ice carving (second annual); animal tracks; dog-sled racing (second annual); ice thickness measuring; and weather cancellations (not quite its own topic, lol).

Spring Session:
Then, we'll have one more "regular session" (6 weeks of classes, followed by a marketplace day and possibly, an end-of-year field day).
