Having a good working knowledge of math vocabulary is especially important for geometry learners. Here are 119 pages worth of wonderfully constructed definitions, constructions, formulas, properties, theorems, and postulates. This is a...

Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Proving triangles are similar is often an exercise in applying one of the many theorems young geometers memorize, like the AA similarity criteria. But proving that the criteria themselves are valid from basic principles is a great...

Pupils explore the meaning of the ancient Greek word aretê and the place of virtue in historical athletic competition and modern sports. They begin by reading an informational text on the goal of sports in education, and then...

"The Gettysburg Address" is the basis of a series of activities that not only model for learners how to conduct a close reading of a text, but also how a close reading can help them comprehend a difficult text. The detailed, step-by-step...

Why is that graph wider? Pupils learn about stretching and shrinking graphs of square root, absolute value, cubic, and quadratic functions. They study both vertical and horizontal stretches and shrinks in addition to reflections. 

Are history textbooks plagiarized? The New York Times article, “Schoolbooks Are Given F’s in Originality,” looks at this question and forms the basis for a lesson on textbooks and plagiarism. The very detailed plan includes resource...

Students examine "masterpieces" and mass-produced objects as they discuss humankind's inventiveness and creativity. They also analyze the role of problem solving in the creation of masterpieces and mass-produced items.

Film poems? To concluded a poetry unit, writers select one of their own poems and create a film that brings to life the sounds and images of their work. Included with the detailed unit plan are daily lessons, student examples, a list of...

What a creative lesson! Learners make sushi dishes using printmaking methods. They use a  variety of techniques including those involving under glazes and clay. There are instructions and pictures to make this process easy for both...

Use a vocabulary chart to introduce math functions. The class defines a list of mathematical vocabulary terms on a worksheet, as well as completes equations and expressions. They examine word problems and practice transcribing them into...

Invite your class to consider how to respond to a conflict. Designed to be used alongside Secret Saturdays by Torrey Maldonado, a lesson plan focuses on a set of terms: conflict, escalate, deescalate, conflict resolution, denial,...

Functions help make the world make more sense. Individuals model real-world situations with functions. They match a variety of contexts to different function types to finish a helpful resource.

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Learners consider a set of questions to determine a series of transformations that will move one figure to another. Once the series is determined, the pupil then determines whether the pre-image and image are either congruent...

Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

Examine the process of rotating images to visualize effects of changes to them. The fifth lesson plan of 18 prompts pupils to rotate different images to various degrees of rotation. It pays special attention to rotations in multiples of...

A lesson looks at the Pilgrims and Wampanoag tribe during the first Thanksgiving. Scholars compare and contrast information presented by an online activity then discuss their findings. Learners examine the two group's daily routines and...

Students analyze symmetries of quadrilateral tilings and discover how various types of symmetries, used alone or in combination, can generate the same pattern in more than one way.

Pupils define properties of rectangular prisms. In this geometry instructional activity, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.

Students explore the properties of rectangular prisms. In this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.
