Co teaching ?

Kerri • Mommy to our rainbow baby- 12-3-16
So I am one day away from spring break! I think I'm more excited for it that the kids lol! Now I just have to get through today without killing one of my co-teachers? Has anyone here ever been in a co- teaching. Classroom? If so how does it work? Just interested to see how other systems do it because some years it's great and some years it's awful! It's all about your partner(s)
