If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Create three dimensional objects in an applied science activity. 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.

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...

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.

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...

Master place value with a series of lessons that use math journals, manipulatives, and place value mats. Kids follow the instructions to represent numbers of all sizes with base ten blocks and recording sheets. 

Learners explore the idea that primitive virtual 3D objects can be reshaped to infinitely original combinations using additive and subtractive methods. They create 3-D objects with a computer which necessitates a cooperation of...

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...

Scholars make a giant scale model of an object. They will take a regular item and enlarge it to five times its length and width. They attempt this same concepts with a 3D model.

Students investigate nets as they relate to volume and area. In this geometry instructional activity, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about...

Third graders describe 2D and 3D shapes. In this geometry lesson, 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 have in...

Young scholars create three dimensional shapes using concept maps. In this geometry instructional activity, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate...

Students build replicas about nature and sports. In this geometry lesson plan, students build 3D replicas of nature and sports objects in teams.

Students 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.

Students explore recognizing, counting and sequencing numbers 1-10. In this primary math introduction lesson plan, students participate in 6 computer sessions that integrate short films, music and drawing in order to bring beginning math...

Pupils estimate and measure exact. In this geometry lesson, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their 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.

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...

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...

Primary geometers create a picture using tangrams. In this geometry instructional activity, 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...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this instructional activity. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is...

Learners 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...

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.
