We have partnered with the BBC Education team to provide Teacher Training on the BBC micro:bit playground survey. As part of this special Institute of Imagination x BBC micro:bit webinar, we show teachers how their class can use micro:bits to collect data and find out how much they get moving during break time! We explore how to code the micro:bit to become a physical tracking machine and then collect, explore and investigate the data with their class as part of the BBC micro:bit playground survey.
