This Fall, my husband is teaching Algebra II and Personal Finance. Algebra II in particular has loads of calculator exercises. I plan to have a few for Biology, too. We’ll do some calculator exercises. We lend out calculators to our students. I just bought two more TI 83 graphing calculators from Good Will online to have on hand during classes. I paid $29.97 with shipping for two TI 83 plus calculators. My target price is under $15 each including shipping for calculators which work. My target price for a TI 84 calculator is $30–which is why I only have three. Good Will online has a number of listings. Don’t forget to check the shipping and handling fees, which vary widely among Good Will stores.
