Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

Create concrete examples of triangle congruence for your classes. The eighth installment of the 29-part module sets the stage for studying triangle congruence. Given a set of criteria, math scholars use constructions to build a specific...

How can you draw a number? A set of questions takes learners through the reasoning for why a geometric construction can be drawn to represent the square root of a number. An interactive helps visualize the construction.

Explore constructions through an interactive online lesson. Given an example of an angle bisector construction, learners investigate the markings to determine the method used. Challenge questions help solidify the steps. 

Cut it in half with a compass and straightedge! Using construction tools, a video shows how to create an angle bisector. The presenter points out what it means to bisect an angle in terms of the measure and distances from the sides of...

Use the parallel lines to find your way. After first reviewing geometric constructions and the relationships between angles formed by parallel lines and a transversal, young mathematicians write proofs for theorems relating to parallel...

Shore up engineering knowledge with some building activities. Scholars design a foam beam, create a structure from playing cards, and construct a paper tower that won't topple over in the wind. Along the way, they learn about engineering...

What are the basics for building a rocket out of a two-liter bottle? The procedures outline the basics to create an air- and water-powered bottle rocket. Prior to launching the rockets, teams perform safety checks to ensure their designs...

Learners examine three different geometric solid shapes and their nets. They answer multiple choice, spatial awareness questions where they determine which view: front, top or either, the net represents.

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Investigate polygons from rectangles to triangles to octagons. Each level of the five-problem series targets a different grade level. Beginning with the level A problem, learners examine the relationship between area and perimeter by...

English teachers around the world cringe when they come across fragments and run-ons in papers. A handout on these poor imitations of sentences helps bring relief by reviewing the basics of sentence construction and by offering...

What is the biggest issue facing young people today? Class members consider the question—along with other provocative pieces from the New York Times—and then try to write their own arguments and back them up with evidence. Once complete,...

Perhaps planning a city isn't so difficult after all. Scholars first perform geometric constructions and investigate how parallel lines are useful in real-world situations. They then work on a city design project, drawing street maps,...

Say no to hate speech! Pupils discover the importance of practicing empathy and inclusivity in digital communities and discuss strategies for responding to online hate speech. Then, small groups develop and present class guidelines for...

Show it can all be proved. Scholars learn the converses of the properties of parallel lines. Using the converses, pupils determine which lines are parallel based on angle measurements and practice using a flow proof to show that two...

Fourth graders construct a relief map of the Big Island of Hawaii. They work in groups to conduct research, design and construct the map. Students use clay, gessoed boards and reference maps in their projects.

Students familiarize themselves with the construct and measure menus. They demonstrate how to use the Sketchpad Calculator. They draw a triangle and construct the centroid. They shade in each of the small triangles and measure the area.

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Role play community members who are both for and against the construction of a dam. Research the pros and cons and then hold a classroom debate. This activity ideally follows a series of stream studies, links to which are included. Use...

Who wouldn't want to know more about the Palace of Versailles? Discuss the purpose of the palace, palace life, and the construction of the great palace. Slides contains images and informational text. 

This engineering activity gets youngsters working together to design and construct a bridge. Each bridge is tested in front of the class to discover how much weight it can hold before showing any change in form. The lesson plan does not...

Enough with the talking, let's build something! In the fifth step in the engineering design process, young engineers build a prototype to test their ideas. The activity walks them through the process of evaluating it step-by-step....

For this geometry worksheet, young scholars construct angle bisectors of two provided rays using a straightedge and a compass. There are 6 questions.
