Clothes for one-off one day trip

We are visiting family in Ohio and taking our early teen kids to snowboard for one day. We are from the gulf coast, so dont have any gear and trying to figure out bare minimum we can get by with that will keep them safe, warm, and enjoying themselves but not bust the bank because its a one-off experience.

It appears mad river mountain only rents board, boots, and helmets. We are avid backpackers so we do have high quality wool baselayers, midlayers, and light weight quality rainjackets if any of that is usefull.

Additionally, they both wakeboard and skate, but neither have ever snowboarded or snowskied. Im planning on getting them private lessons. We only have one possible day to go, so curious if the group thinks it will be worth it to them (fun wise, not financially). Thank you in advance for your suggestions and help!
