Label angles of parallel lines to analyze the angles created by a transversal and two parallel lines. They graph their lines and observe the similarity and difference in the angles.
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...
Curated OER
Triangle Midsegment
Learn how to calculate the length and midsegments of triangles. Students differentiate between similar and congruent triangles. They create a spreadsheet with their findings.
Curated OER
Diagonals of Quadrilaterals
Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, high schoolers use the TI to create a visual of their shape.
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.
Curated OER
Exploring Power Functions 2
Young mathematicians learn to write algebraic equations. They solve and graph different polynomial functions with different powers. They then graph radicals and identify the domain and range.
Curated OER
Exponential Transformations
Perform transformations on exponential functions! Teach your class how to perform dilation, compression, and translation. They graph exponential functions using the TI Calculator.
Curated OER
Logarithmic Transformations
Using the TI calculator to visualize and make predictions, high schoolers perform transformation vertically and horizontally on logarithmic graphs in order to solve problems.
Curated OER
In the Forecast, a Flurry of Concerns about Snow
Students consider the effects of climate change on snowfall and how a lack of data in snowfall collection impair climate change research. They, in groups, investigate different effects of snowfall and make recommendations to lobbyists.
Curated OER
Thirsty for Drought Relief
Students research a variety of drought-related concerns, acting as part of a 'drought preparedness taskforce.' They propose next steps for the government to take in case of drought and assess the viability of these proposals.
Curated OER
Defining Issues
Students work on a 'campaign committee' to define civic issues that are important to them and their community. They write letters to city officials with proposals for how to address these issues.
Curated OER
One Stage at a Time
Students explore the psychological coping mechanisms of cancer patients and relate individual cancer survivors' stories to Dr. Kubler-Ross' stages of grief. They use first-person accounts, discussion and journals to explore these concepts.
Curated OER
Death Be Not Proud
Students consider various opinions concerning the execution of Timothy McVeigh. They formulate, and share in writing, their own perspectives on his execution and on the lasting impact of the Oklahoma City bombing.

Augmented Matrices
Pupils write systems of equations in an augmented matrix and enter it into their calculator. They use the reduced row echelon function on the calculator to solve the system of equations.
Curated OER
Volumes of Rectangular Prisms
High schoolers determine the volume of a rectangular prism. They then maximize and minimize the volume given variable side lengths. Finally, they factor the volume equation to determine the side lengths.
Curated OER
Local Linearity
In order to investigate local linearity, students graph the function on the TI-calculator and zoom to observe the change in slope on the line. They incorporate technology to visualize these problems.
Curated OER
Sign of the Derivative
Learn how to investigate the change in a graph by dragging the cursor to observe the change in the function. They use the TI calculator to graph their parabola.
