Students judge, compare and construct two-dimensional figures using a variety of materials.

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

Explore two and three-dimensional shapes. Learners first examine three 2-D shapes and determine which of three 3-D figures could have made that shape. The wording here is a bit confusing; make sure your kids understand what it is...

Third graders evaluate the attributes of cones. In this space shapes lesson, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.

Students find two dimensional shapes in three dimensional figures. They determine the shapes that make up the faces of three dimensional figures of common classroom objects such as crayon boxes.

Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

Explore the relationship between 2D and 3D shapes by having your class view representation of shapes and investigate their symmetry. They will create a solid object from diagrams and describe the reflection or rotational symmetry. In the...

Learners find the surface area and volume of the solid figures by measuring the length and the height of each face and base. They use concrete models to derive formulas for finding perimeter, circumference, area, surface area, and volume...

Learners explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Learners define geometric solids...

Young scholars explore the concepts of length, perimeter, and area. For this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Geometry could be called the study of figures. An overview of the figures found in a typical geometry course contains a study of different triangles, quadrilaterals, and regular polygons. 

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...

High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Everything old is new again. The Los Angeles J. Paul Getty Museum presents a lesson on how Greek black-figure painting influenced eighteenth century Neoclassical artists. After looking at a series of examples, class members create their...

In this 2 and 3 dimensional figures learning exercise, learners determine whether given shapes are regular or irregular. A reference web site is given for additional activities.

Writing can become one-dimensional if authors don't involve all their senses. First, scholars observe a strange object which, ideally, they can touch and even smell. Without using certain words (you can create a list or have the class...

The Olmec were an ancient people native to Mexico who lived from 1000-500 BC. Young artists examine the Olmec piece Seated Figure to analyze the use of body language to communicate a tone or feeling. They then use clay or play-dough...

Students identify and match pictures of three dimensional shapes while playing a board game with peers. They take turns with their partners in spinning the spinner and moving to the next space on the game board that shows the same shape.

Students examine works of art that convey the idea of working together and analyze how artists use foreground, middle ground, and background. They use two-and three-dimensional materials to create a work of art.

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...

Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.
