I am very fortunate that my school district invests in training teachers. For the past two school years, we have had optional professional workshops in the winter and summer. There are multiple days with choices available for different grade levels. Last year, they were all separated by grade band. This year, there's more overlap between the grade levels on different days. So yesterday was 3-6, today was 4-6, and tomorrow is 6-8. I didn't realize that I could have also gone yesterday, but it worked out anyway because yesterday was my own kids' first day of the second semester. I am so glad they made the switch, because previously there was minimal involvement from people at my middle school, and we are the only middle school in the district. So today I got to work with not just teachers from my school, but from all of the elementary schools. It always helps to have additional perspectives from both sides. It also helps that everyone who was there signed up to be there....
