Here you can find detailed lesson plans videos for an introduction, troubleshooting and information about what we have put in our micro:bit kits. It should be a good place for teachers new to the micro:bit to get started.
Code examples, curricular links, and project ideas using Micro:Bits, Makecode blocks, and some peripherals. This website is in beta until the Feb 1-2 2019 conference and (spoiler alert) will be used in the Micro:Bit Deep Dive session. The website contains many embedded Makecode examples, so it is somewhat slow.
