Discover the lesser-known functions of calculators from Morgan Hamilton, Rachel Hack, and Steve Siuda across four categories: Math, Num, Cpx, and Prb. This tool aims to reinforce previously learned material, including concepts from 5th Grade Fractions to High School Probability and Advanced Calculus. Engage in collaborative exercises using random integers to explore GCD, LCM, and advanced statistics calculations. Compare different calculators and discussing their usability in classrooms, fostering better educational experiences.

Lesser KnownFunctions By: Morgan Hamilton, Rachel Hack, and Steve Siuda
Overall Themes • Tool for executing previously learned material, NOT in place of learning • The below functions in our menus were found in the Math Standards: • 5th grade- Fractions and Decimals • 6th grade- lcm and gcd • 8th grade- working with radicals and integer exponents • High School- Rectangular and Polar Forms, Conjugates (Geometry), Probability and Statistics • Advanced courses- Derivatives and Integration
Group Exercise: Use your calculator to generate two random integers between 1 and 200, being A and B. The GCD between A and B = C. The LCM between A and B = D. Find D to the C power. Find C raised to 1/D, then change the decimal to a fraction.
Statistics on our Calculators Step 1: Calculate your own height in inches. Step 2: Compile a class list of height’s. Step 3: Calculate average, standard deviation, etc. Step 4: Represent data in graphs. • Standard Met Through this Exercise: • Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
Class Discussion • Your experience with teachers modeling the TI calculators. Any with Casio? • Who remembers how to use your calculator beyond simple functions? • Would a visual interface help in classrooms? • Reasoning- First impressions of TI website? • Are you surprised? What’s your take?
