Course A supplies--marbles needed?

When I finished my training, I received an email from with a link to their lists of supplies on It has marbles listed as being needed for Course A, but I went through all the lesson plans and didn’t see them. Did I miss them? What lesson uses marbles? I’m the coordinator of technology for my district and need to get supplies ordered and don’t know if we need these and how many. Thanks for your help!

Hi Kim,
Apologies for the confusion! Marbles are no longer required for Course A. I will make sure the correct team gets notified so we can update the list that is sent with this email.
I hope this helps!
