I'm in a unique situation because my school is expanding next year (opening a new building) and we are adding classes at every grade level - so I can basically choose my grade level for next year. Right now, I am in my second year teaching 5th at a K-5 school. I taught 1st at another school for my first two years, and am not interested in going back to primary. I am considering 4th grade. I do love 5th, but I get along very well with the 4th grade teachers (we are going from 2 to 3 teachers in 4th and 5th), and I like their content fine. I think I may like their math and science content better. I would probably miss teaching colonies and the American Revolution. 4th is CA history, which I also like ok, but maybe not as much as I like U.S. Reading and writing seem pretty similar, with the exception of some books that are ok in 5th but may have content too mature for 4th. What are some of the differences between 4th and 5th? I have a few in mind, but I'd like to hear from others, especially those who have taught both grade levels. Thanks!
