Yep, we reset the devices after each workshop to give users a clean slate to work from each time. In other workshops, learners can have their own SD card that they bring along each session.
We generally use standard Raspbian and set it up how we like it using PiBakery.
PiBakery is a tool for creating and customising Raspberry Pi SD cards, we wrote up a guide on LibraryMakers.
Then, after each workshop, we can just write the SD cards again.
You could also just reformat the cards and download NOOBs again.
There's not a lot out there about using the micro:bit for adult learners (most of the online guides are still aimed at the initial Year 7 user group) but wearable or reaction game activities would work well as introductory activities for adult learners.
Technology Will Save Us have quite a few activity guides, like this one on making Shadow Puppets:
And the Pollocks Puppet Theatre Lights activity looks amazing (a bit more involved though):
Rasbian comes with Minecraft Pi, a custom edition of Minecraft made for Raspberry Pi that's good for games clubs.
You can also try the Pi-top OS (developed for the Pi-Top computers but can be installed on other Raspberry Pi devices). This gives you access to other games like CEEDuniverse as well as the Minecraft Pi edition.

The CamJam EduKit 1 is pretty good as a starter project and only £5 as well. Starting a Jam next Jan so will post if I get some good ideas!
Hi! LEGO Education has recently uploaded a bunch of free lesson plans around making/rapid prototyping with LEGO. The lesson plans are aligned with products, but you can customize them to use with any collection of LEGO you have on hand. They have a Wearables lesson plan and it gives students inspiration on types of wearables to make and encourages thinking on why to make one. You can also use anything to prototype making a wearable, and then use low or high tech electronics to make your invention come to life. I have taught this lesson using basic LEGO + mixed media, WeDo 2.0, Mindstorms, and with LEGO Simple and Motorized Machines and Mechanisms. The inventions have ranged in scale from spinning corsages to talking and sensing walking sticks for the blind.
Here's the link to the LEGO Edu lesson plan:
I second Gizmos and Gadgets or purchasing bulk individual bits. Sometimes the kits have bits that are rarely used.
For beginner workshops some good bits are:
LEDs (long, bright, RGB)
a sensor (light or motion)
Great workshop starter projects (can be found on the littleBits Website)
Artefacto have a makered subscription service for those who have a makercart (currently in beta) it includes one activity per month with all details and worksheets. We're considering developing a second level of subscription where you'll receive 4 activities per month.
