I don't have lists for two of my kids yet, but I would say I'm almost done. I still need some ziploc bags, a pair of shoes for my 5yo, and I'm still waiting to find out if DD needs a specific calculator for Algebra. I'm going to call the school tomorrow and see if they'll tell me so I can watch for sales.
Make sure you speak with either the Math Department Head or the Curriculum & Testing Coordinator. Either should know which calculator they use. I would not take just anyone's word for it at the school.
Also to everyone that has a "school supply list" this is a general list. Once your student is in their class or classes their actual teacher might have a totally different list.
I always just make sure I have dividers, folders and college ruled loose leaf paper. Otherwise I do not worry about the other stuff until they are in class. Yes, that is a pain but after working in the school system for 10 years and my children being in private and public schools for 12 I have learned I like to wait.
