... to a positive (which affects the q value). For example, the point (-(2), -p/4) is equal to ((2), 3p/4). Notice that the difference between the two numbers is that • The sign of r has changed from negative to positive. • We added p to the q value (in radians).

The sum of the interior angles of regular polygons
The students will construct triangles within regular-sided polygons to determine the sum of the interior angles. They will then, using statistics, create a linear regression to determine the relationship between the number of sides of a regular polygon and the sum of its interior angles.https://education.ti.com/en/activity/detail/the-sum-of-the-interior-angles-of-regular-polygons
Shortest Distances
Students will explore three situations involving distances between points and lines. First, the minimum distance between two points leads to the Triangle Inequality Theorem. Then, the shortest distance from a point to a line is investigated. Finally, students find the smallest total distan...https://education.ti.com/en/activity/detail/shortest-distances
Discovering the Circumcenter and Centroid of a Triangle
The students will find the circumcenter by constructing perpendicular bisectors of the sides of a triangle. They will also find the centroid by constructing the medians of a triangle and discover that the centroid is 2/3 of the distance from each vertex along each median.https://education.ti.com/en/activity/detail/discovering-the-circumcenter-and-centroid-of-a-triangle
Points of Concurrency in Triangles
In this activity, students will use their Nspire handhelds to discover the different points of concurrencies in triangles. The students will take advantage of the dynamic capabilities to discover the circumcenter, incenter, and centroid of triangles.https://education.ti.com/en/activity/detail/points-of-concurrency-in-triangles
Possible Lengths of Sides of Triangles
The first problem in this activity has students explore the varying length of the third side of a triangle when 2 sides are given. They will discover that the length of the third side must be between the difference and the sum of the other 2 sides. The second problem extends this idea of the le...https://education.ti.com/en/activity/detail/possible-lengths-of-sides-of-triangles
Classifying Quadrialterals
In this activity, students will classify quadrilaterals graphed on the Cartesian coordinate plane. Students will justify their classifications with segment and angle measurements as well as slope measurements. A review of the hierarchy of quadrilaterals is at the beginning of the document.https://education.ti.com/en/activity/detail/classifying-quadrialterals
Soda Problem: Finding the relationship between Sodium and Sugar
The students will use nutrition label data of certain sodas to create and analyze a scatterplot of the amount of sodium versus the amount of sugar in various soft drinks. They will put the data into lists, create scatterplots, discuss correlations, acquire the line of best fit, and predict other...https://education.ti.com/en/activity/detail/soda-problem-finding-the-relationship-between-sodium-and-sugar
Rational Numbers: Number Line
Drag a point along the number line and compare the mixed numeral, improper fraction, decimal and percentage forms.https://education.ti.com/en/activity/detail/rational-numbers-number-line
Rates of Change and Slope
This lesson was designed for the Grade 10 Applied curriculum in Ontario. In that course, students are expected to connect the rate of change of a linear relationship to the slope of a line.https://education.ti.com/en/activity/detail/rates-of-change-and-slope
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
Solving Systems of Linear Equations from Four Perspectives
Using the on-screen directions and the more detailed directions here, students will investigate four ways to solve systems of linear equations: graphically, numerically, with a data table and by matrices. Some prior familiarity with the basic functions of the TI-nspire CAS is needed. Students sho...https://education.ti.com/en/activity/detail/solving-systems-of-linear-equations-from-four-perspectives
Arc length and Area of Sectors
This is an introduction to finding the arc length and area of sectors of circles. Students should have the formulas for Circumference and Area of circles.https://education.ti.com/en/activity/detail/arc-length-and-area-of-sectors
Car Sales
In this activity, students' will create a box and whisker plot using a list. The list will be sent using TI-Navigator™ and contains the number of car sales since 1970. They will determine the values in the box plot and answer some additional questions.https://education.ti.com/en/activity/detail/car-sales
Approximation of Pi
Students will measure the circumference and diameter of a variety of different circles. They will graph the class' values of (d,c) on the coordinate plane and use linear regression to approximate pi.https://education.ti.com/en/activity/detail/approximation-of-pi
Approximation of Pi Using an Area Model
Students will approximate pi by setting up trigonometric ratios and calculating the areas of regular polygons inscribed within and circumscribed about a circle.https://education.ti.com/en/activity/detail/approximation-of-pi-using-an-area-model
