Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

Construct yourself a winning geometry unit. A set of lessons introduces geometry scholars to constructions and proofs with compasses and straightedges. It also covers triangle congruence through transformations. This is the second of...

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,...

Show the class the world as they've never seen it before—from way above! Learners try to unravel the mysteries presented by rich satellite imagery, learn to interpret topographic maps, and study erosion by constructing their very...

Creating buildings that reach hundreds of feet into the sky is no easy task. The third instructional activity in this series begins with four activities that engage young architects in exploring the major challenges that are faced when...

Technology or engineering teams are given a task to design, construct, and test the efficiency of a structure that will foster an even temperature throughout an entire sunny day. Intended as a long-term project, pupils research, plan,...

Construct tangent lines and make the connection to tangent functions. An informative lesson plan reviews the geometry origins of the tangent function. Pupils use that information to determine how to construct a tangent to a circle from a...

Fuel cells are being called the "energy source" of the future. Allow your high school chemistry class to construct a miscroscale fuel cell, complete with all components to generate energy. This engaging activity will allow them to apply...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Learners construct their understanding of measurement and dimensions in this step-by-step approach that begins with an all group vocabulary introduction, consisting of measuring objects and dialoging using measurement vocabulary....

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Engineering design projects serve as great opportunities for collaborative problem solving. In this case, students work in small groups designing, building, and eventually testing a structure that meets a teacher-specified objective. It...

Everyone has opinions. The trick is to learn how to disagree in a way that doesn't cause problems. The activities in the final lesson in the Communication Module focuses on learning how to express opinions constructively. Middle...

Some conversations are easy and enjoyable, while others are horrific! To begin a lesson on communicating constructively, class members list examples of conversations that are easy, average, and those that are difficult and identify what...

Kids take a critical look at each other's work in order to understand the editing process while providing constructive suggestions. This handout really sets learners up to successfully offer constructive critique to their...

The construction of skyscrapers is no simple undertaking, involving the careful coordination and planning of many different people. The third lesson in this series explores this detailed process by first teaching children about the main...

What does it take to prepare for a construction project? In an engineering lesson, youngsters examine how a Ferris wheel can turn and carry a load without falling apart. After reading up on big wheel designs, they create a model using...

November is NaNoWriMo, or National Novel Writing Month! If your class is participating (or simply doing a narrative writing unit), this peer review instructional activity is part of a larger unit which can be easily found online. Once...

Who knew that a possible answer to Earth's energy resource problems was lurking deep beneath the ocean's surface? Part four of a six-part series introduces Earth Science pupils to methane hydrate, a waste product of methanogens. After...

The last unit in the series by Core Knowledge focuses on alternative spellings, nouns, verbs, conjunctions, subject-verb agreement, using commas in a series, constructing sentences, and following the writing process while writing...

Environmentally friendly engineering teams construct a water wheel and experiment with its speed and the resulting amount of weight it can lift. Consider following this activity with two more of the same title by the same publisher when...

Some types of verbal communication are just more difficult that others. High schoolers engage in a series of activities that are designed to help teens make difficult conversations easier and more effective.

Groups of young oceanographers get to use action figures to experiment with the property of buoyancy! This memorable lesson plan provides detailed background information, a link to the laboratory worksheet, and thorough instruction...
