TI’s Color Connection

Whether it is overlaying graphs on top of photos to visually illustrate trends or showing a family of functions, color can help kids make vital math connections, and the $165 TI-Nspire CX does the trick. Thinner and lighter than the previous Nspire calculator, it uses rechargeable batteries and comes with software for a teacher to create a wide variety of lesson plans and, with the optional WiFi adapter, use the calculators for classroom assessments. It’s approved for use on the SAT and AP exams.
