Students in Lisa Cessna’s Geometry, Algebra II and Technical Math classes at Sandpoint High School are getting hands-on time with the latest technology. Approximately 250 students per year in classes ranging from Pre-Algebra to Calculus and Statistics are using these new calculators.

“It is exciting and rewarding to see my Technical Math students work through solving systems by hand and then reworking the same problems with a TI-84+,” says Cessna. “As technology has become prevalent in education and in the workplace, it is vital that we include TI-84+ calculator activities in every level of mathematics.”

This new graphing technology encompasses exploring basic polynomial functions and encourages students to practice with scientific functions such as logarithms and trigonometry. They will graph relations, functions, and sequences, then evaluate parameters for statistical data such as central tendency and measures of variation.
