Trig Patterns
In this activity, students will use the unit circle to examine patterns in the six trigonometric functions. Students will compare angles created with the x-axis in all four quadrants and discuss with one another what is happening at each coordinate as they move the point around the circle.https://education.ti.com/en/activity/detail/trig-patterns-@ns
Once and For All...Absolutely
The activity is designed to be a lesson in solving absolute value inequalities. The intent is to distinguish the kinds of solutions that absolute value inequalities have and the forms of stating the solutions. More importantly the activity considers two methods of solutions: a graphing method and...https://education.ti.com/en/activity/detail/once-and-for-all---absolutely
The Open Box: An Exploration of Maximum Volume
The students will solve the problem of finding the maximum volume of a box cut from an 18 x 24 cm peice of paper in several ways. The student will actually cut out and form several different boxes. The student will fill the boxes with "starburst" candies and then use their TI-Nspires to analyze...https://education.ti.com/en/activity/detail/the-open-box-an-exploration-of-maximum-volume
What is a Fraction?
This activity helps students understand and visualize a fraction as a number that can be represented as a point on a number line.https://education.ti.com/en/activity/detail/what-is-a-fraction
Equivalent Fractions
This activity helps students understand that two fractions are equivalent (or equal) if they are located at the same point on the number line. Students recognize that, as with whole numbers, when ordering fractions the larger of two fractions is located farther to the right on the number line.https://education.ti.com/en/activity/detail/equivalent-fractions
Fractions and Unit Squares
This activity is intended to extend the concept of fraction to unit squares, where the unit fraction fraction is a portion of the area of a unit square.https://education.ti.com/en/activity/detail/fractions-and-unit-squares
Constructing Similar Triangles
Students investigate three different methods of constructing similar triangles.https://education.ti.com/en/activity/detail/constructing-similar-triangles
Pythagorean Proofs
In this activity, students will explore proofs of the Pythagorean Theorem. Students will explore the proof of the Pythagorean Theorem using area of squares, area of triangles and trapezoids, and by dissection. Students will then be asked to apply what they have learned about the Pythagorean Theorem.https://education.ti.com/en/activity/detail/pythagorean-proofs_1
Points on a Perpendicular Bisector
Students will explore the relationship between a line segment and its perpendicular bisector. The concept of a point that is equidistant from two points is illustrated.https://education.ti.com/en/activity/detail/points-on-a-perpendicular-bisector
Midpoint Quadrilateral
This problem presents an opportunity for students to think about properties of quadrilaterals, and also to work on confirming observations through geometric reasoning. If your state has adopted the Common Core State Standards, this alignment might be helpful: Geometry: Prove Geometric Theorems G....https://education.ti.com/en/activity/detail/midpoint-quadrilateral
Application of a Circle: Angles and Arcs
Students use the properties of circles, angles, and arcs to help design a courtyard with a star-shaped design.https://education.ti.com/en/activity/detail/application-of-a-circle-angles-and-arcs
Pick's Theorem
Using the TI-Nspire grid screen, students will discover Pick's Theorem relating to the area of a polygon with vertices on grid points.https://education.ti.com/en/activity/detail/picks-theorem
Basic Trig Transformations- 84
In this activity, students will use the Transformation Application to change the values of parameters in trigonometric functions and to determine the effect that each change has on the shape of the graph. Students will then use this knowledge to write equations for sine and cosine functions.https://education.ti.com/en/activity/detail/basic-trig-transformations_84
