I would like more information on how to teach CS Discoveries Unit 6 Physical Computing without the circuit. It gives an option to do so, but when I click on run without board, it does not do anything.
Welcome to the forum!
This page does covers budgeting for the circuit playground and the discounts available (near the bottom of the page). I pair students up in my classroom so I only needed one set.
I hope this helps but let us know if you have other questions,
