I just wanted to give you a heads-up that I've posted free tic-tac-toe boards for grades K-5. They have PDF versions and digital versions you can use online!
Your students can play at home with someone or you can share your screen and play together. (They would pick an activity and complete it. Then you could move their piece to that square.)
Each freebie includes 8 different boards that have a mix of ELA and math topics. We made sure every activity is something that can be done easily from
home.
