I recommend that every student invest in their own graphing calculator in my class, whether that be a TI-84 or an Nspire CX.  I do provide a class set of Nspire CX's in my class, but when the student gets some practice at home on the homework, it would be best for them to have their own calculator.  I am aware they are expensive, so this download is a cheaper option where you can put an Nspire CX calculator on your home laptop or pc.  It is a free 30 day trial, but to keep it and use it beyond that it is $30.

It is at the website:   www.education.ti.com    and find the tab downloads.

This paper is what I go over with all of my students on the first day of school and explains my grading breakdown with category weights and discipline policy.
