Parallelograms - Discovering Their Properties
Students use the TI-89 with CABRI™ Geometry to discover properties of parallelograms. They will construct a figure and use the definition to disvoer the figure is a parallelogram. (Topic - parallelograms)https://education.ti.com/en/activity/detail/parallelograms--discovering-their-properties
Proportional Flag
Students will use the concepts of similarity to create a scale drawing of the national flag, that is large enough to cover most of a football field.https://education.ti.com/en/activity/detail/proportional-flag
What's the Angle?
Students discover properties of interior and exterior angles of convex polygons using the TI-89 and Geometer's Sketchpad. (Topic - Interior and Exterior Angles of Convex Polygons)https://education.ti.com/en/activity/detail/whats-the-angle
What's the Spin?
Students discover properties of rotations using the TI-89 and CABRI Geometry II by rotating a triangle around a point and through a specified angle. They will discover the definition of a rotation. (Topic -- Rotations and their relation to reflect)https://education.ti.com/en/activity/detail/whats-the-spin
Set Design
Students will use similarity concepts, and the dimensions of the carvings on Mt. Rushmore to create a proportional representation of the carvings for a stage backdrop.https://education.ti.com/en/activity/detail/set-design
Dividing Notes
Students create an altered musical melody by dividing fractions. They compute the value of notes in terms of fractions and make their sum equal to the time signature.https://education.ti.com/en/activity/detail/dividing-notes
Conics in Geometry
This lesson has students construct 3 conic sections through geometric definitions. Using the CABRI™ Geometry II application for the TI-89, students construct a parabola, an ellipse, and a hyperbola. (Topics - geometric shapes.https://education.ti.com/en/activity/detail/conics-in-geometry
Dilation
Students use the Cabri Geometry II Plus software to investigate the geometric property of dilation. They vary the scale factor and examine the effect on the dilation of a triangle.https://education.ti.com/en/activity/detail/dilation
Going in Circles - Inscribed Angles
This lesson has students discover properties of inscribed angles in a circle. Students use the Geometer's Sketchpad application for the TI-89 to construct a circle and an inscribed angle. (Topic - circles)https://education.ti.com/en/activity/detail/going-in-circles--inscribed-angles
Exploring the Unit Circle
In this activity, students explore the properties of a unit circle and its mapping functions.https://education.ti.com/en/activity/detail/exploring-the-unit-circle
Number of Regions - An Introduction to the TI-Nspire CAS
This activity uses the problem of determining the maximum number of regions formed by n lines in a plane to introduce new users to the TI-Nspire CAS. It illustrates the variety of features available on the TI-Nspire CAS, as well as the ability to look at one problem from multiple representations ...https://education.ti.com/en/activity/detail/number-of-regions--an-introduction-to-the-tinspire-cas
Volumes of Rectangular Prisms
This lesson will introduce students to many of the algebraic graphing features of the TI-89 calculator, especially the Maximum command. This will be accomplished by solving volumes of right rectangular prisms. (Algebra / geometry activity)https://education.ti.com/en/activity/detail/volumes-of-rectangular-prisms
Fast nines and Fast tens
Students learn how to solve a mathematical equation with a missing addend. Students will learn the combinations of addends to find the sums of nine and ten. Students practice math facts with accuracy and immediacy for sums of nine and ten.https://education.ti.com/en/activity/detail/fast-nines-and-fast-tens
The Best Cell Phone Plan
Students will compare two cell phone plans and determine which plan is better for a specific situation. They will utilize both tables and graphs to make their decisions. For this activity, students need prior experience writing linear models.https://education.ti.com/en/activity/detail/the-best-cell-phone-plan_1
The Antics of Statistics
Students learn/review some of the different measures of statistics and see how to use those measures to analyze a data set. Students also participate in a discussion about how statistics can be used to achieve a variety of results.https://education.ti.com/en/activity/detail/the-antics-of-statistics
Ready, Set... Solve!
In this coding activity, students will create a fast-paced game to help practice solving multi-step equations.https://education.ti.com/en/activity/detail/ready-set-solve
To Simplify or Not to Simplify...
Students will discuss fractions and what it means to simplify them using prime factorization. Students will then use the calculator to simplify fractions manually as well as investigate both the prime factorization and greatest common factors of the numerator and denominator in various fractions.https://education.ti.com/en/activity/detail/to-simplify-or-not-to-simplify
