I LOOVE this idea! The kids are always playing the game app on my phone, but now they can have their own travel tic tac toe board! Magnetic tic tac toe from Altoids box. Keep one in your purse or make them as gifts for the kids' friends?
I'm thinking of doing weekly minilessons on confusing Homophones where the kids can record what we learn in their writing binders to frequently reference for editing drafts more accurately and independently.
