Students define a plane and a solid shape. In this geometry lesson plan, students compare and contrast different geometric shapes as they relate to solids. They name the geometric solids based on their sides and edges.

Explore the concept of creating and describing 2D and 3D shapes.  Using geometry your scholars will describe the attributes of shapes and their properties.  They explore and discover what happens when you combine shapes and...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

In this math worksheet, students study the properties of plane shapes and solid figures. Students fill out a chart after they have calculated the number of flat surfaces, edges and vertices.

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...

Young scholars brainstorm names of plane and solid geometric figures. Afterward, they explore the skyline of large cities and note their agricultural shapes. Using construction paper, students build 3-D geometric structures to create a...

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...

For this solid figure worksheet, students write 3 possible combinations of views and a solid figure for a set of 3 plane figures. Students are given choices in a box at the top of the page. Students then draw and label top views of a...

In this solid and plane figure instructional activity, students pick which solid figure they could trace to make the plane figure shown. Students complete 4 multiple choice questions.

Learners identify and classify solid geometric figures. In this geometry instructional activity, students bring in objects that look like solid shapes and identify their attributes. Learners identify the number of surfaces and faces on...

Time to move into the third dimension! Learn the names of the geometric solids and count faces, edges, and vertices. Then learn to recognize nets that create a given solid. 

For this platonic solid worksheet, students observe five solids and draw a net of each three-dimensional figure. Students examine a tetrahedron, an octahedron, an icosahedron, a cube, and a dodecahedron. This is a one-page worksheet.

In this geometry skills learning exercise, students respond to 4 questions that require them to examine geometric figures and change them to solid figures and plane figures.

Young mathematicians examine area of different figures with the same cross-sectional lengths and work up to volumes of 3D figures with the same cross-sectional areas. The instruction and the exercises stress that the two...

A list of instructions for this exciting Geometry Jeopardy game is included on slide 2. There are a total of 25 clues and 5 categories, including: solids, triangles, lines, angles, and grab bag. Tip: Play this Jeopardy game with your...

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

In this solid figures worksheet, students read the word problems about the solid figures and find the figure that follows the rule.

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

What do you get when you slice a prism? Pupils discover that the answer depends on how the prism is sliced. The second half of the 29-part module focuses on three-dimensional objects. Learners use their two-dimensional vocabulary and...

Students construct two dimensional models to illustrate squared numbers. In this geometry activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between various...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...
