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...

Sew up pupil interest with an engaging, hands-on lesson. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses of included...

Primary geometers create a picture using tangrams. In this geometry lesson, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

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

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

Create three dimensional objects in an applied science lesson plan. The goal is for your class to recognize, compare, and model shapes. Using cookie cutters and clay or play dough, they create models for three-dimensional shapes.

Three, two, one...liftoff! Elevate math skills to new heights while having a blast. A great resource that combines entertainment and education for children of all ages.

In this three- and two- dimensional geometry worksheet, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of each...

Seventh graders investigate the area and volume of 2D and 3D figures. For this geometry lesson, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret their...

Discover the difference between standard and non-standard units of measure with your class. They differentiate between rectangles and squares, read a book, measure a peer's height. They then discuss  measurement methods, make...

Ask elementary students to explore shapes in everyday objects. They will discuss the elements of design and describe the shapes they see in visual images. Students will then design and "build" a new 3D shape. Finally they will show and...

Students 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. Students define geometric solids...

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Young scholars examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

Learners research tall buildings and identify the geometric shapes used in the construction of the buildings. They compare shapes and infer why some are better than others in building. They produce a multimedia presentation of geometric...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Young scholars use their understanding of 3D on 2D to make a representation of a 4D form on paper.

In this exploring projective geometry worksheet, students use computer software for instruction, then answer 9 questions about 3D drawings.

Twelfth graders examine different dimensions and units which go with a particular dimension. They explore the concept of linear measurement versus area. Students estimate area of 3-D objects. They practice converting from one unit of...

Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.

Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.

Discover 2D shapes and 3D objects from different views in Antarctica!

Practice your knowledge of all possible cross-sections of common 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Match 3D objects with their 2D cross-sections. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
