Classmates apply midpoint concepts by leapfrogging around the complex plane. The 12th lesson in a 32 segment unit, asks pupils to apply distances and midpoints in relationship to two complex numbers. The class develops a formula to find...

Scientists don't have a ruler long enough to measure to the stars, so they rely on math. Scholars learn to calculate the distance from Earth to a star using the parallax method. They use angle measures from different perspectives to...

Small groups work through two guided activities to derive the distance and midpoint formulas for the coordinate plane. The activities begin with concrete examples and move to abstract.

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

To work through the complexity of coordinate geometry pupils make the connection between the coordinate plane and the complex plane as they plot complex numbers in the 11th part of a series of 32. Making the connection between the two...

At the end of this activity, your number crunchers will have a better understanding as to how to describe graphs of velocity versus time and distance versus time. It is easy for learners to misinterpret graphs of velocity, so have them...

Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...

Size within the solar system is a difficult thing for pupils to imagine. Using everyday objects, they build models to show the scale between the sun, moon, and Earth. They situate their props in proportional distances between the objects...

With many factors leading to a great athlete, does height make Usain Bolt unfairly fast? Middle schoolers conduct analysis to change the running distance of the Olympic races to be proportional to the height of the participants. They...

When Einstein first heard the theory of the expanding universe, he dismissed it as bad physics. Now scholars learn about the theory and how scientists prove it has merit. Through a hands-on simulation and videos, class members measure...

Long considered the symbol of safe harbor and steadfast waiting, the lighthouse gets a mathematical treatment. The straightforward question of distance to the horizon is carefully presented, followed by a look into the...

Willy Wonka takes center stage in a lesson about direct and indirect characterization. Scholars read a passage from the story about Wonka's Grand Entrance and watch a film clip of the same, noting examples of direct and indirect...

"Yuns betta outten the lights!" Colloquial language is the focus of a instructional activity that asks middle schoolers to consider the pros and cons of using idioms. They read articles, match expressions with their meaning and place of...

Clement Moore's "Twas the Night Before Christmas" models the power of descriptive language for middle schoolers. They identify the similes and metaphors in the tale and consider what these descriptions add to the story's emotional...

I came, I saw, I conquered! Parallel structure, employed by writers even before Julius Caesar, is the focus of a lesson that teaches young writers the power of this rhetorical device. Class members analyze speeches by Dr. Martin Luther...

Young historians may be surprised to learn that the Constitution of the United States includes provisions that protect the institution of slavery. Groups examine four clauses of the Constitution, as well as other primary sources, and...

Put your high schoolers' orienteering skills together. Reading a compass and reading a map. In this assignment the class will use their compass and the map scale to determine the distance of a given route.  If they finish their...

Is there a way to measure variability? The ninth resource in a series of 22 introduces mean absolute deviation, a measure of variability. Pupils learn how to determine the measure based upon its name, then they use the mean...

Why do some stars in a constellation appear brighter than others? Using a get-up-and-move astronomy activity, scholars explore perspective and the appearance of constellations in the sky while developing an understanding of the...

Very specific diameters are given for blowing up three different balloons to represent, in scale, the moon, Earth, and Mars. In groups of three, amateur astronomers explore scale measurements and distance in space.

You're safe, when calculating the odds of stealing second base! Learners compare the rate of a runner to the distance the ball travels, in a lesson that explores right triangles and measurement. Full of discussion questions and fun...

Young scientists gain a better understanding of space, the solar system and its vastness by creating a scale model. Students first need to calculate the distance between each of the nine planets according to the size of their scale. This...

Students make several models of the solar system to learn the positions of the planets in the solar system as well as relative distances and sizes. Creation of these models will help them identify the planets by size, shape, color,...

Young scientists learn how to select a scale factor for a large scale model. Then they figure the scale for each of the planets and the distance between them. Finally, they construct a giant scale model of the solar system and answer...
