Graphing quadratic functions can be overwhelming. Not only are you working with translations and transformations, but a quadratic function can be written in three different forms. Follow the steps below and check your work using Desmos and you will be a pro in no time. An accordion style foldable adapted from High Heels [...]
One of the benefits of graphing calculators and graphing software is that it allows you to learn things about functions and equations that would have been tedious to explore via pencil and graph paper. Families of graphs is a concept that starts with a "parent" function or equation and asks you to compare "child" functions [...]
Link students' experiences with functioning and malfunctioning pop (soda or Coke) machines to the definition of a mathematical function. Students quickly realize that someone will come fix the pop machine when it starts giving out extra sodas for a single input (malfunctioning). http://youtu.be/r6EjdtZZb9o
There is nothing quite like flying a kite on one of the first breezy days of spring. Is it possible to determine how high a kite is flying from a photograph? What would you need to know? If you were flying a kite, what tools could you use to determine its height? http://youtu.be/KknxRn6e9RA [...]
Texas Instruments has dominated the graphing calculator market since the TI-81 debuted in 1990.

Low Tide Versus High Tide These images show low tide and high tide on January 19, 2011 near the Golden Gate NOAA tide gauge in the San Francisco Bay. The question is, is this normal or is there cause for concern? Data from the tide gauge for this time frame is available from the [...]
https://www.youtube.com/watch?v=LXhADp-KPg8 When graphing the absolute value function, create a t-chart and list values for x. Then plug those values into the equation to find y. Be sure to treat the absolute value like a parenthesis and perform the order of operations using it as a grouping symbol. Anything within the absolute value is performed first. Once [...]
Absolute Value To understand how the absolute value can be applied to the real world, we'll look at two topics: What is considered normal with regard to the temperature of the human body and Fuel economy of two vehicles: a Honda Odyssey and a Nissan Altima. http://youtu.be/4BaOWrzeOOM The absolute value of a number can [...]
