Second Grade needs
Remember, they have just finished first grade and will not have any of the skills you see at the beginning of the year in fourth grade. Morning meetings are really important at this age. This will set the tone for the rest of the day. Many times the kids really need to share something with the class and this is a great time to get that done.
I use chalk boards a lot, but I noticed the poster before me suggested dry erase boards. Which ever you prefer, make sure you have lots of markers or chalk and maybe they have an old sock in their desk to erase the boards. I use these for sight word, word family work, DOL and when we are working on new math concepts. This way each child is responsible for their own work and I can see quickly if they have the problem correct or not.
Big books are still good for this age. Big writing pads are too. The 2ft x 3ft size. I use a spiral notebook for journals. They are looking really nasty now, and I am deciding if I want to use them again, or go another route next year.
Manipulatives, lots of them for math. I use the plastic ties that comes on bread and buns for mine. They come free with the bread and I can always get the kitchen staff to save them for me. Since the beginning math is working addition and subtraction from 1 - 20, if you have a small class, it doesn't take long to get them saved.
I'm starting to ramble, just have fun with the little ones. You will wonder why you taught older children!
