What grade to teach?
I have taught all three of your choices. While my personal favorite is 4th, I think you have to decide if you want primary or intermediate. Going from pre-K to second will be a jump, but not as large as going to 4th. In second, the kids are less independent than your other choices, especially at the begininning of the year.You will be doing more guided reading instruction and phonics than in an upper grade. I like 4th because the literature choices in reading are terrific, and the kids possess enough basic reading skills to read and write about books at a higher level than the earlier grades. The curriculum can be challenging, but there is more depth to it. You will need to do more planning in most curriculum areas than for a lower grade because of this concentration of material. I love the personalities of the kids at that age. At second, you have a little less testing pressure and more time to "enjoy" the curriculum than the older grades. Would you be self-contained at 4th, or departmentalized? Our 4th grades switch for leveled math and reading, which is why I chose to go to a K-3 building because I prefer being self-contained. My recommendation would be to observe classrooms at the different levels if you can. If you go into a third grade at this time of year, they are closer to 4th, so you might want to go as low as 1st in your observations to see how a beginning of the year second grader might be. Good luck to you! I don't think you will go wrong with any of your choices.
