Dilations from the origin have a multiplicative effect on the coordinates of a point. Pupils use the method of finding the image of a point on a ray after a dilation to find a short cut. Classmates determine the short cut of being...

Ramp up a design challenge. Class members design ramps to meet a client's requirements to comply with the American with Disabilities Act. The scholars create a scaled graph of their designs and determine the equations of the lines on...

Turn the class around. Scholars define rotations of multiples of 90 degrees and create algebraic mappings for them. After an introduction to symmetry, pupils determine which letters of the alphabet have rotational and reflectional...

Combine measurement, following directions, physics, and art with one fun activity. Learners read a set of instruction to create three different kinds of paper airplanes. They measure, fold, and fly the planes, and record data and answer...

Represent complex numbers in two ways. Pupils use the interactive to convert polar and rectangular representations of complex numbers. The learners drag an overlay back and forth over the coordinate plane to reveal the polar coordinates...

Go the distance with a far out resource. Individuals use an interactive to create right triangles on a coordinate plane to help find distance between two points. Challenge questions aid them in developing the distance formula.

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...

Take foldables to all new heights. Pupils build and fly different types of paper airplanes in the 14th portion of a 22-part unit on aviation. Groups collect data on distance and flight time for each plane and compare the data from the...

The resource is the real deal. Individuals investigate the imaginary zeros of f(x) = x^2 + 1. They accomplish this task by using an interactive that shows input values x = a + bi and output values x^2 + 1 on a complex plane.

Reinforce math vocabulary instruction with a set of flash cards. Fifty-six cards offer either a bold-face word or a picture representation equipped with descriptive labels. Terms include centimeters, gallons, square units, and more!...

What determines which ball rolls the fastest — the weight, the radius, the material, or something else? Scholars select two balls to race down the inclined plane, determining their material and radius. As they race, the simulation graphs...

Pupils gather measurements of real-world objects that have slopes. They then plot the measurements and find an equation of a line that fits the measurements. Finally, groups investigate the ADA and determine whether different ramps meet...

The class takes a trip about the school and find four places to measure the rise and run of objects that represent slope in the building. Pairs work together to calculate the slope of each object and determine whether any ramp they find...

Visualize the nth roots of unity. Pupils calculate the nth roots of unity and find all n roots. Learners plot the solutions in the complex plane and observe that they are the vertices of a regular n-gon inscribed in the unit circle....

Understanding how functions transform is a key concept in mathematics. This introductory lesson makes a strong connection between the function, table, and graph when exploring transformations. While the resource uses absolute value...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

The snake goes sssss and the plane goes nnnnn! Practice letters and their sounds with a collection of activities. For each letter, kids get to color, practice the sound, and practice writing the letter. This is group one. See the...

Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.

Let's go fly a kite ... oops, a paper airplane! The 13th segment in an aviation unit of 22 relates the parts of an airplane to paper airplanes. Pupils learn the functions of the control surfaces of a plane to really make their knowledge...

What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

The Berlin Blockade may not take up as much space in the history books as other events of the Cold War, but for the citizens of west Berlin in 1948—and the events to follow between the Soviet Union and the United Stattes—those 318 days...

Learn similarity through a transformations lens! Individuals examine the effects of transformations and analyze the properties of similarity, and conclude that any image that can be created through transformations is similar. The...

Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

You know about the tangent function, but what are tangent lines to a circle? Learners investigate properties of tangents through constructions. They determine that tangents are perpendicular to the radius at the point of tangency,...
