Begin building the foundation for future math success

The calculator can display two forms of fractional results simultaneously, allowing students to begin making crucial mathematic connections. Challenge them to manually simplify fractions and mixed numbers in traditional numerator/denominator format or enable the calculator to automatically simplify them or change them to decimal equivalents.

Engage students in self-directed problem-solving

Encourage students to explore math on their own with built-in flash cards that challenge their addition, subtraction, multiplication and division skills. Set the flash cards for the appropriate age and type of operation. The flash card functionality gives students hints when a wrong answer is entered and includes an internal scoreboard enabling teachers to check each student’s progress.

Graphing Calculator purchase was wonderful

I am a math teacher in Ogden, Utah. We have ordered from Underwood twice now, buying TI-84 Plus CE graphing calculators both times. They were easy to purchase, a great price compared to others, and arrived quickly. No complaints here! Definitely recommend!

Wonderful source for TI calculator add ons

The Ti 84 launchpad board and RGB led board are hard to find new for just a single user and definitely not at such a good price. Prompt shipping and everything arrived well packed. Seriously great source if you are looking for small quantity at great value. Thanks!

Best experience!

I ordered a calculator late Monday night that I needed by Wednesday. I communicated with Jake several times via email and once on the phone throughout the next day. Had my calculator before noon on Wednesday. Every response to me was quick, helpful, and very courteous!! Great company and customer service. I will order through them in the future and highly recommend others to do the same.
