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?
