TI83+/TI-84+ Calculator Instructions
Several units in the CPM Statistics and Probability Resource assume that students have daily access to a TI-83+ or TI-84+ graphing calculator and that the teacher has access to a whole-class calculator display. It is expected that students will have their graphing calculators available at all times, including for any additional problems you may assign for homework.
Teachers should note that the procedures for other TI graphing calculators (TI-89, TI-73, and others), and calculators from other manufacturers, are very different.
Before teaching any lesson that uses technology, be sure to set up and test your equipment in advance to make sure that batteries, software, and the projection system are working properly. It makes sense to have extra batteries and a replacement projector bulb readily available. It also is a good idea to walk through the activity using the actual technology in the classroom yourself before the day of the lesson to review the key strokes and anticipate any issues that may arise during the lesson.
Much more detailed operating instructions for your calculator than are provided in this appendix can be downloaded from education.ti.com by clicking on “downloads” and then “guidebooks.”
