Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, learners calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

Investigate the application of vector transformations applied to linear systems. Individuals use vectors to transform a linear system translating the solution to the origin. They apply their understanding of vectors, matrices,...

Each of these number sentences has a corresponding set of blocks, which will no doubt help your visual learners grasp multiple-addend addition. Learners examine the sentences and match them to their block representation. Consider also...

Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

Can you see your class working on spatial visualization? The first installment of a five-part module introduces the concept of spatial visualization and provides a 12-question diagnostic assessment to test spatial visualization skills....

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Ron Toomer, a famous roller coaster designer, suffered from motion sickness. Pupils design their own roller coasters, learning about potential and kinetic energy in the process. Labs focus on the importance of drop height, energy...

Connect geometric sequences to exponential functions. The 26th installment of a 35-part module has scholars model situations using geometric sequences. Writing recursive and explicit formulas allow scholars to solve problems in context.

Tenth graders discuss collage and photomontage techniques and artists, and how the art form can convey cultural or current issues. They research a collage artist, then design a topical or personally symbolic collage. Present their...

Third graders divide by 2 and 5. In this math lesson, 3rd graders label the parts of a division sentence. Students solve division sentences using multiplication.

Learners investigate the connection that exists between Algebra and Geometry. They classify two and three-dimensional figures. Pupils use formulas to solve problems in geometry and use appropriate measuring devices in the right contexts.

Every movement in the world can be measured and even motionless objects can be significant indicators of movement. Focus on motion graphs that feature distance vs. time, speed vs. time, and positive and negative acceleration.

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Explore vocabulary related to three-dimensional shapes. An instructional website describes the characteristics of different geometric solids. Learners can use an interactive component to view nets, faces, vertices, and edges of common...

Fifth graders examine the impact of Benjamin Franklin's ideas on the goods and services available in Colonial America as well as analyze the importance of Franklin to modern society. While listening to "How Ben Franklin Stole the...

Students identify various geometric shapes. Apply the given formulas to determine the volume of these shapes. Design their own container to conform to specifications provided. Use their knowledge of volume formulas and shapes to compute...

Students identify two- and three-dimensional figures and associate them with real-world objects.  In this geometry lesson, students are read The Very Hungry Caterpillar by Eric Carle and complete several activities including a chart...

In this object pronoun activity, students review object pronouns. Then they use like and don't like to use object pronouns in sentences.

Seventh graders investigate 2-D and 3-D objects. In this geometry activity, 7th graders begin to understand spatial reasoning. Students look at pictures of the NYC Skyline and discuss what it looks like from different views. Students use...

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

In this direct object pronouns worksheet, students read sentences and identify direct objects, then change the direct objects to pronouns. Students determine seventeen answers.

Third graders describe 2D and 3D shapes. In this geometry instructional activity, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see...
