Application of Slopes
Students will apply the concept of slope to a real-world problem about building a staircase. They will use the slope ratio, vertical change over horizontal change, to find the slope of staircase. Then, students will recognize how a positive or negative slope applies in a real-world situation.https://education.ti.com/en/activity/detail/application-of-slopes
Applications of Parabolas
In this activity, students will look for both number patterns and visual shapes that go along with quadratic relationships. Two applications are introduced after some basic patterns in the first two problems.https://education.ti.com/en/activity/detail/applications-of-parabolas_1
Common Denominator
In this activity, students will use an interactive model that multiplies the fraction by "1" to help determine the common denominator. Then they will use what they have learned to add and subtract fractions without the same denominators.https://education.ti.com/en/activity/detail/common-denominator_1
Beat the System
This can be used as an introduction to Systems of Equations. Students can work in groups or alone. They are shown graphs of the three different types of systems of equations and then asked to write equations of lines to create another set of systems.https://education.ti.com/en/activity/detail/beat-the-system
Pi Song - Little Help
Solving literal equations with Pi. In this activity, students will explore formulae that have Pi in it. Animations and multiple choice, self-check questions, make this activity accessible to Algebra students. The equations make this activity of interest to geometry and physics classes for a short...https://education.ti.com/en/activity/detail/pi-song--little-help
Families of Rectangles
Students create a family of similar rectangles and then write the equation of the curve that will connect the upper-right vertex of each rectangle. Students will then create a family of rectangles that have the same area and will write the equation of the curve that connects the upper-right verti...https://education.ti.com/en/activity/detail/families-of-rectangles
Triangles and Slope - Is the Triangle Possible?
Students will construct triangles that match specific criteria. If it is possible to construct the triangle, the students have to construct the triangle and state the slope of each side. If the triangle is impossible to construct, the students must write a detailed explanation as to why it is im...https://education.ti.com/en/activity/detail/triangles-and-slope--is-the-triangle-possible
Quadratic Yoga: Transforming Quadratic Functions
Students will use the vertex form of a quadratic function to fit a graph to a given scatter plot. They will also graph functions given a transformation description.https://education.ti.com/en/activity/detail/quadratic-yoga-transforming-quadratic-functions
Slopes with Starburst
Students will use Starburst to conduct an experiment that analyzes slope. The data will be entered into TI-Nspire and evaluated. Students explore concepts such as flat/steeper slopes and constant versus varied slope. Students also simulate distance versus time graphs using meter sticks and hot...https://education.ti.com/en/activity/detail/slopes-with-starburst
Birthday Simulation
In this activity, the students will conduct a simulation to predict the probability that two people in a room of thirty will have the same birthday.https://education.ti.com/en/activity/detail/birthday-simulation
Rectangles and Parabolas
Students will tackle a traditional problem from the Algebra I curriculum geometrically, numerically, graphically, and algebraically: Sixty feet of fencing is purchased for the grounds crew to fence off a rectangular portion of property for a garden. The owner has made it perfectly clear that h...https://education.ti.com/en/activity/detail/rectangles-and-parabolas
Slope, Midpoint and Distance
The student will interact with a line segment and will report various conditions on a handout. Positive, negative slope, distance, and midpoints will dynamically calculate as the student drags either endpoint around.https://education.ti.com/en/activity/detail/slope-midpoint-and-distance
Vertex form of a Parabola
Students will use graphing technology to understand a quadratic function written in vertex form.https://education.ti.com/en/activity/detail/taks-vertex-form-of-a-parabola

Sums of Sequences
In this activity, students will develop formulas for the sum of arithmetic and geometric sequences. Students will then find the sum of sequences using the formulas developed.https://education.ti.com/en/activity/detail/sums-of-sequences_1
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
