For both my Math 7 and Math 7ACL classes, we will be using the TI-30XS Multiview calculator. Although we do not have a class set that you may borrow from on a daily basis, we do have loaners available through the Salk library. I recommend that even if you purchase one, that you also take out a loaner from Salk. That way you can leave one at home, and keep one with you in school. The calculator is used for the entire school year, and can be used on all quizzes and tests, including the final exam. The loaner form will be posted within Google Classroom once the year begins - simply fill it out and bring it to the library. They will then issue you a calculator for the year.
