One of the biggest challenges I faced with co-teaching was keeping myself from stepping on the other teacher's toes (so to speak). I was constantly thinking about keeping a respectful boundary from the other teacher. This checklist below would be invaluable if I was still co-teaching today.
It sounds really simple, but writing down the responsibilities of each teacher could help tremendously.
