Helping Your Student Be Successful with High School Mathematics

Calculator Information for 20-21: 

Many courses require a graphing calculator. Texas Instruments is offering a free Chromebook app for the TI-84 which will be accessible on high school student Chromebooks for the 20-21 school year. Check with the classroom teacher to see if this version will be suitable. Some students may prefer to work with a physical calculator. All students may need a physical calculator for standardized tests.

AP Calculus BC uses the TI-Nspire CAS which needs to be purchased.
