Use a one-stop resource for everything you'd possibly want to teach about quadratic functions and models. Scholars analyze key features of quadratic functions as well as transformations of functions through seven activities....

Geometry in life-sized dimensions! Using enlarged graph paper, pupils perform a series of transformations. By recording the initial and final placement of the images, they are able to analyze the patterns in the coordinates during a...

Model real-life structures with mathematics. A project-based lesson presents a problem situation requiring classes to develop a function to model the St. Louis Arch and the Rainbow Bridge in Arizona. They create their models by...

Learn about constructing figures, proofs, and transformations. The seventh unit in a course of nine makes the connections between geometric constructions, congruence, and proofs. Scholars learn to construct special quadrilaterals,...

Create the perfect prom night image using the Law of Reflection! An interactive lesson explores angles of reflection when looking in a full-length mirror. Learners change the distance from the mirror and length of the mirror and watch...

How did scientists discover what lies beneath the earth's surface? Dig a hole? X-ray vision? Guide your class through the types of seismic waves and how these waves helped shed light on Earth's many layers. The included resources provide...

Many people know that fiber optics are used in delivering the Internet, but are surprised to learn they are also used in astronomy. Scholars explore light, reflection, and fiber optics through hands-on activities. They discuss...

Scholars manipulate the amplitude of the graphs of sine and cosine, notice how the change in amplitude is reflected in their graphs, and answer several questions about the concept they noticed.

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...

Now you see it, now you don't. Our moon seems to pull a disappearing act from time to time—but why? Take your seventh grade scientists above and beyond to discover the truth about the moon and the role it plays in Earth's little...

Transform lizards onto different locations. The interactive provides a diagram of a lizard and several locations. Pupils use their knowledge of transformations to move the lizard to the different locations and use the tools of GeoGebra...

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Is the inverse a function? Scholars learn how to examine a function to answer this question. Using an online interactive, they examine the properties of inverse functions to compare to the original function.

Bank on geometry to line up the shot. The resource asks the class to determine the location to bank a cue ball in a game of billiards. Using their knowledge, class members determine where to hit the bumper to make a shot and discuss...

Transform your instruction with an exploratory lesson! Young scholars manipulate absolute values and quadratic functions to look for transformation patterns. They use the patterns to write general rules of transformations.

Dive into an activity that may cause a little reflection! Building from the first lesson in the series of two, learners explore transformation using unfamiliar functions. The key takeaway is that applying transformations to any function...

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...

Don't cry over broken pottery. A cross-curricular lesson challenges pupils to consider how to restore ancient pottery. Using a computer program and their knowledge of transformations, they come up with a way to recreate the original...

How do you see yourself? Young mathematicians consider whether it's possible to view their whole bodies in a mirror with a length that is half their height. They write a letter to a friend explaining their positions mathematically.

Transform the thinking of transformations with six sample items that illustrate the first four standards in the eighth grade geometry domain. Items use the coordinate plane to transform figures and analyze the relationship of the figures...

Create emotional superheroes with a unit equipped with several activities and lessons designed to establish coping skills and practice tools that boost healthy habits. Through discussion, chants, writing, and drawing, scholars learn to...

Excellence, ethics, and engagement are the three E's featured in a unit that promotes good work among elementary scholars. Through discussion, reflection, read-alouds, activity worksheets, and written responses, participants gain...

What types of materials absorb sound? Learners explore sound waves, the decibel scale, and how different materials affect sound. Then, they use their knowledge of sound meters to complete a STEM engineering design task to build...

A trip around the world sounds nice, but for now we'll just have to make do with Google Earth. Pupils use pictures of landmarks to apply geometry concepts. They determine whether each building has bilateral or rotational symmetry, search...
