Hi Monica,
We have little bits, dash & dot robots, cosmo robots, and offer a choice of online hour of code activities so that no sign in is needed/or permission slips. We recently purchased the rasberry pi, cue robot and will try to incorporate those. We usually run a day and half with preference for our STEM academy to sign up for class time/slots on those days. Hope this helps.
Respectfully,
