Making Hay While the Sun Shines & Not Losing It in the Rain (The Geometry of the Big Round Bale)
This activity explores the volume of the hay bale and the percent of loss as the radius of the bale decreases. The extension collects data from the constructed cylinder in a spreadsheet and graphs it. The graphs are modeled with quadratic functions and transformations of quadratic functions can...https://education.ti.com/en/activity/detail/making-hay-while-the-sun-shines--not-losing-it-in-the-rain--the-geometry-of-the-big-round-bale
Maximizing a Paper Cone's Volume
The net for a conical paper cup is formed by cutting a sector from a circular piece of paper. What sector angle creates a net that maximizes the cone's volume? In this activity students will build concrete models, measure the dimensions and calculate the volume. Next, students will use a const...https://education.ti.com/en/activity/detail/maximizing-a-paper-cones-volume
Angle and Perpendicular Bisectors in a Triangle
The students will examine where the perpendicular bisectors and angle bisectors of a triangle intersect. The students will circumscribe a circle around the triangle and will inscribe a circle within the triangle. There is a page at the end of each activity with the circle constructed if the s...https://education.ti.com/en/activity/detail/angle-and-perpendicular-bisectors-in-a-triangle

Printing Your Own Books - is it more cost effective?
In this activity, students will create functions based on real-life scenarios, fill out a table of values, and critically analyze characteristics of graphs.https://education.ti.com/en/activity/detail/printing-books
Investigating Inscribed Angles
Investigation of the relationship between inscribed angles subtended by the same arc or chord.https://education.ti.com/en/activity/detail/investigating-inscribed-angles
Inscribed and Central Angles in a Circle
This activity explores the relationship between inscribed angles subtended by the same minor arc. The second problem explores the relationship between inscribed angles and central angles subtended by the same minor arc.https://education.ti.com/en/activity/detail/inscribed-and-central-angles-in-a-circle
Inscribed Regular Polygons
Students will calculate the changing area and perimeter of inscribed polygons as the number of sides increase. The measurements will be recorded in a spreadsheet for analysis. Students will be learning to use the measurement tools and the Hide/Show function of the TI-Nspire. Students will be aske...https://education.ti.com/en/activity/detail/inscribed-regular-polygons
The Filly Zoo
During this activity, students are charged with the task of designing the shapes of the habitats of the animals that inhibit the Filly Zoo. The students are asked to use their TI-Nspire calculators to create geometric shapes, measure the dimensions of the shapes, and make informed decisions abou...https://education.ti.com/en/activity/detail/the-filly-zoo
Goodness-Of-Fit
Students test claims of whether given distributions "fit" theoretical distributions. Students will work through two problems, one in which the theoretical proportions of each category are the same and one in which they are not. Students will use spreadsheets to calculate test statistics and the I...https://education.ti.com/en/activity/detail/goodnessoffit_1
Modeling Daylight Hours
Students are provided with data on the daylight hours for two Canadian cities measured three times per month in 2007. The student's task is to create graphical and algebraic models of the data and to interpret the meaning of each of the parameters in the algebraic models. The student will also ...https://education.ti.com/en/activity/detail/modeling-daylight-hours
Unit Circle template
This is a one page unit circle template that you can copy and paste into a document that you are creating. To make it fit the screen, change the document settings to "float 3," and I used degrees instead of radians for all of the angles up to 180 degrees. You will also want to view in "handheld...https://education.ti.com/en/activity/detail/unit-circle-template
Law of Sines: The Ambiguous Case
A simple model is used to illustrate the various possibilities of the ambiguous case of the Law of Sines. Students manipulate the model to create each of the possible cases and then make conjectures about the relationship between the various given measurements and the number of possible triangle...https://education.ti.com/en/activity/detail/law-of-sines-the-ambiguous-case
Have You Lost Your Marbles?
In this activity, students will create a bridge between two chairs and use a slinky to attach a bucket to the bridge. Students will add objects to the bucket and determine the relationship between the number of items added and the distance from the floor.https://education.ti.com/en/activity/detail/have-you-lost-your-marbles
Getting Ready for Quadratics
This activity is intended as a skill-building exercise to familiarize students with TI-Nspire skills they will need to work through a unit studying the properties of quadratic functions. The activity includes exercises on Creating a Scatter Plot, Finding a Curve of Best Fit, and Tracing a Function.https://education.ti.com/en/activity/detail/getting-ready-for-quadratics
