Calculator
This is the CX II CAS Model and please note this is new model for 2019-20. Be careful you are not buying the CX I or CX I CAS model. We have previously had students purchase the CX I model and if you have access to one of these that is fine. It is recommended to buy the CX II CAS model if you are buying new this year. In class we will continue to use the CX I model. Note it is not required to buy this calculator but can be beneficial and it will be used throughout high school and possibly beyond. Please note prices vary so please shop around to get the best deal. The cheapest I have seen is around $145 through Schoolsmart
Desmos (online Graphing Calculator)
This is an excellent free online calculator that can be used particularly if a student does not have access to a calculator at home.
