Students will explore volume conjectures and solve problems by applying the volume formulas to composite figures.

This task challenges a student to demonstrate understanding of the concept of two dimensional shapes and their properties.

Describes the basic three-dimensional figures students will encounter in elementary Math and in the world around them, and makes mention of a few unusual ones.

This tutorial features templates and instructions to make the following solids: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.

Have fun and learn by making a box and then find out its maximum volume as well as other problem-solving activities, including making a table of your results and drawing a graph.

How many different cuboids can you make? Learn how and learn how to represent data with your results.

Use this rhyming description of Max's Fantastical Zoo to make some amazing animals from geometric shapes. There is a teacher's guide for easy lesson planning.

Students make a series of geometric drawings of points, obtuse angles, rays, polygons, and the like. Each child is given one but not allowed to show anyone else. The drawing is then taped to the back of the child in front of them. The...

This lesson is a unique and fun way to review perimeter, angles, and types of adjectives. Students pick an object from the classroom that will fit in a paper lunch bag. They investigate their object and fill in the attached sheet. You...

Get your spy glasses ready! For this weeklong adventure, children will explore shapes and their attributes and use this knowledge to decode a secret message. Children will learn about two-dimensional (flat) and three-dimensional (solid)...

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...

This two-part geometry lesson plan has students identify, describe, and classify two-dimensional shapes. Students engage in hands-on activities including identifying shapes in the classroom, creating patterns with shapes, identifying...

Use the shapes provided and figure out how they fit together to make a 3 X 3 cube at this one page website. The solution is readily available right at the website.

In this activity, students will understand the basic geometric concepts of parallelism and perpendicularity, and will also able to use rectangular coordinates to make congruent objects. They will display understanding of parts of...

"The volume of a cube can be developed by considering unit cubes, a single row (longs) of unit cubes or a single layer (flats) of cubes using this applet." This easy software makes it possible to easily construct a cube and take it...

Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.

Diagrams and discussion of the "collection of 1-dimensional records" that make up a CAT scan.
