Creating a Cyclic Quadrilateral
Identify and make conjecture about properties of cyclic quadrilaterals. High schoolers use the TI Navigator to create different shapes and draw conclusions.
Curated OER
Exploring Diameter and Circumference
Learn how to identify the diameter and circumference of a circle. Then, collect data on a circle and relate it to the diameter and circumference of a circle. Last, plot data and find the line of best fit.
Curated OER
Glide Reflections
Perform reflections and transformations by having your high schoolers create glide reflections from translated shapes. They use the TiNavigator to explore transformations.
Curated OER
Completing the Square Algebraically
Using TI-Nspire, scholars rewrite quadratic expressions by completing the square. They change the equation into vertex form. By the end of this lesson plan, they should be able to change any quadratic equation into vertex form.
Curated OER
Solving Systems using Elimination
Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

Permutations & Combinations
Young mathematicianss predict the outcome of an event. Learners solve problems using permutations and combinations. They use the TI calculator to see the different combinations and how the groupings occur.
Curated OER
Permutations
Learn how to solve the probability that an event will occur. Learners also employ permutations and combinations to find the amount of time it takes for an event to occur. They use the Ti to create a visual of the events.
Curated OER
Parametric Projectile Motion
Learners relate projectile motion to parametric equations as they identify the velocity and angle of a projectile. They create a picture on the navigator to visualize the word problem.
Curated OER
Slow Down - Speed Up
Pupils explore the concept of distance and time as they use a CBR to mimic distance v. time graphs. Learners walk towards and away from the monitor to create various distance v. time graphs, then discuss what motion creates certain graphs.

Properties of the Centers of a Triangle
High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This lesson requires the use of Cabri, Jr.
Texas Instruments
What's the Trig?
Learners determine the trigonometric relationships within a triangle as they construct a right triangle on the Ti-89. They find the sine, cosine, and tangent of various angles of their triangle construction.

From Expressions to Equations
Learners differentiate between expression and equation by evaluating integers and observing the difference. They use the TI to see the steps to solve problems.
Curated OER
Nested Similar Triangles
Nested triangles have been created so that they share a common vertex and vertex angle. Learners drag the endpoints of the side that is opposite the common angle to discover the conditions that make the nested triangles similar. When...

Solving Systems with Row Operations 2
Have your class solve equations using matrices by teaching them how to factor systems of equation to identify the point of intersection. They create their matrices on the Ti and perform row operations to simplify.
Curated OER
No bones About It -A Mosasaur
Students model a paleontologist's activities. They identify dinosaur bones and reassemble them into a skeleton of an extinct reptile.
Curated OER
A New Life
Young scholars write a paper about how their life would be different if fractions, decimals and percents did not exist. The teacher leads a discussion after the papers are written.
Curated OER
CO2 Blow Out!
Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.
Curated OER
Just Passing Through
Students examine the functions of the kidney and its place in the urinary system. They discuss how astronauts go the bathroom in space, examine labeled diagrams of the urinary system, and draw a large scale drawing of the excretory...
