At my previous school, we never had PD during the school day. I wish we had them occasionally because I sometimes wanted a break. At my new school, we are implementing the Open Up Math Curriculum. We will have PDs for each unit in the curriculum. I think it would be 7 days that we miss and we would get subs. That seems like a lot considering that I would likely take 2-4 sick/personal days as well. I think it’ll be great to collaborate about the units though. How often do you have PD?
