Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...

In this geometry worksheet, students cut out a rectangular prism net. They cut along the dotted lines as indicated the scissors icon, and fold the piece along the solid lines to form the three-dimensional shape. There are no directions...

Seventh graders investigate the mathematical concept of a sector. They apply the concept to an example problem and then move into a more complex application. They find the area of the side of a cone. This is done as students calculate...

Students find the volume of rectangular prisms.  For this volume lesson, students use a formula to find the volume of rectangular prisms.  They discuss the definition of volume and draw rectangular prisms.  Students...

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...

Young geometers need a clear understanding of perimeter, volume, and area. This instructional activity provides a worksheet to help small groups of learners to calculate various measurements of objects and choose the proper units for...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Students investigate measurement through the use of literature through this series of lessons.

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 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.

In this 3D shapes learning exercise, students cut out the 3D shape on the page and fold on the lines to create the correct shape. The learning exercise states which shape should be build with the cut-out.

In this surface area worksheet, students answer 1 word problem given a diagram and other important facts. Students should show their thinking.

Students use centimeter rulers and the attached worksheet containing a scale drawing of a stained glass window. The actual measurements of the stained glass window are given, and students are asked to find the actual measurement of the...

Students investigate geo-profiling.  In this secondary mathematics lesson, students use geo-profiling to determine the most probable location of a criminal.  Students find the centroid of a polygon where the vertices represent...

Fourth graders are introduced to the vocabulary needed to identify the attributes of two and three-dimensional figures. They work together to create a word wall, which contains the geometric terminology being learned.

In this 3D shape instructional activity, students review the names of 4 shapes on page one and color each shape a specific color to match the key on page two.

This two-part reading comprehension exercise asks kids to read a short passage about cubes, rectangular prisms, spheres and pyramids, and then to respond to a series of questions about the article.

Students make three dimensional shapes with nets. In this nets instructional activity, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the...

Review area, perimeter and volume using this lesson. After reviewing key vocabulary relating to these concepts and answering story problems, learners compute the perimeter, area, surface area, and volume of five storage boxes. 

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

Pupils identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students  build a cube by matching colored square faces to a correct word. Pupils then...

Pupils explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Young scholars, in groups, use song lyrics and math to descrie two and three dimensional shapes.

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...
