By selecting the resource, you're already halfway to understanding midpoints. Pupils use a slider to locate midpoints on the coordinate plane. They connect this conceptual understanding to the formula for the midpoint of a line segment.

To be a right triangle, or not to be — that is the question. Scholars drag line segments in an Internet application to see if they form right triangles. Once they get the results of the activity, they connect them to the converse of the...

Challenge your class to use straight lines when estimating the length of a curve. An engaging interactive allows individuals to place line segments one after another along the arc. Learners determine that the more lines used, the better...

Are planes the best shipping method? Using maps, pupils determine the fastest mode of transportation between two cities. Given a list of items to ship, groups decide the best shipping method to finish the 18th segment of a 22-part unit.

The potential of the energy in the class is moving. The third segment in a six-part unit on energy provides a deeper understanding of kinetic and potential energy. Learners understand the relationship between mass, speed, and energy and...

The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy...

Create an egg-citing study of energy. Pupils investigate the effect of height and mass on the overall amount of energy of a falling object. The fourth segment in a six-part series on energy uses a weighted egg falling from different...

Which is the best reflection of them all? Given four diagrams, pupils determine which one shows the most accurate reflection of a quadrilateral. Two images provide the distances of each vertex from the line of reflection, as well as the...

Imagine a world built of triangles. A performance task asks scholars to consider just that. They use their knowledge of special segments of a triangle to make decisions about the area of triangular plots of land.

What can individuals do to give peace a chance in the Middle East? Through a series of activities including viewing segments from a PBS video, class members learn about the complex history of the conflict and about efforts to promote...

The truth will always come out. A short performance task has learners considering a witness statement given to a detective. They apply special line segments in triangles and Ceva's Theorem to prove that the witness is actually lying.

Are some families down to their last generation? The final segment of a two-part climate change series investigates the vanishing Marshall Islands. Scholars divide into research teams to analyze three different individuals whose lives...

Where should the statue be located? The resource explains how to use a compass and straight-edge to construct the perpendicular bisector of a line segment. Using an exam question, the narrator models how to solve an application problem...

Explicitly talk to the class about sequences. A segment of a review series for the General Certificate of Secondary Education math assessment provides a review of arithmetic sequences. Pupils watch a video showing how to find terms given...

Make sure to get enough for everyone. The three-part assessment task requires scholars to calculate with decimals. Learners determine the cost of school supplies and whether the teachers have ordered enough. The assessment is the sixth...

Just how far can I see? The short assessment question uses the Pythagorean Theorem to find the distance to the horizon from a given altitude. Scholars use the relationship of a tangent segment and the radius of a circle to find the...

Take a another look at ellipses. The seventh segment in a series of 23 in a Precalculus module continues to investigate the graph and equation of an ellipse from the previous lesson. Scholars investigate the fact that the sum of...

David Binnington's mural commemorating the 1936 Battle of Cable Street is the focus of a lesson that looks at public art as a form of civic participation. After reading background material about the mural, individuals analyze a segment...

Revisit the relationship between logarithms and exponentials. Learners review the notion of logarithms as the way to solve exponential equations in the 21st segment in a Pre-calculus series of 23. Pupils use the knowledge to prove that...

Connect end behavior to previous learning. Pupils connect finding the end behavior of rational functions to finding end behavior of polynomial functions. The 13th segment in a 23-part unit starts with finding the end behavior or power...

Put everything together in a picture. Scholars take what they learned in the previous three lessons in the 15th segment of a 23-part unit to graph rational functions. They find the end behavior, the horizontal and vertical asymptotes if...

And now moving on to the next story. The last of five lessons in Unit 1: The Big Climate Change Experiment requires groups to create a script for a news segment on climate change. They either make a video of their story or conduct a live...

Take biologists on a journey into the heart of the Covid-19 virus with a series of stunning graphics and explanations about the global pandemic. Animations bring investigators up close to the virus, revealing its structure and movement...

It's time to show what you know! Individuals first review finding the area of polygons using the formulas from parallelograms to regular polygons. They then brush up on finding the area and circumference of circles, as well as reviewing...
