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.

Explore the concept of creating and describing 2D and 3D shapes.  Using geometry your scholars will describe the attributes of shapes and their properties.  They explore and discover what happens when you combine shapes and...

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.

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

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...

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Students 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...

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

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...

Data distributions can be compared in terms of center, variability, and shape. Two exploratory challenges present data in two different displays to compare. The displays of histograms and box plots require different comparisons based...

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.

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...

In this creative music activity from Scientific American, students learn about musical notation and then design their own notations. Great web resource links are alsp provided

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

Students examine a variety of fruit to discover that each has seeds. Through experimentation, they discover the role that fruit and seeds play in a plant's life cycle.

While 3 Dimensional shapes are not mentioned specifically in the Common Core, they do include the term face which is more appropriate for 3D shape attributes.

Second graders will identify the attributes of 3D shapes and measure the edges in inches and centimeters. This lesson contains a detailed plan and videos of students engaged in the activity.

My first graders have been studying the defining attributes of 2D shapes. They are going to love using toothpicks and marshmallows to present their knowledge of 2D and create 3D shapes.

In this lesson, learners will create a shape mobile of 2-dimensional and 3-dimensional shapes made from geometric shapes.

In this lesson plan on solid shapes, students will learn to identify three-dimensional shapes by their attributes and learn to recognize them in the real world.

As a whole group, young scholars will sort a collection of three-dimensional objects into categories by shape. There should be several that fall into each of the categories below: Aligns with 1.G.A.1.

For this lesson, 7th graders slice three dimensional objects to determine what two dimensional shape is created.

Check out this math project about polyhedra! Young scholars will enjoy the hands-on activity while they learn about tetrahedrons, hexahedrons, octahedrons, dodecahedrons, and icosahedrons. [Requires Adobe Reader.]

A geometry instructional activity that examines the history and structure of ancient pyramids and engages students in constructing pyramid models. A comprehensive instructional activity that considers students with diverse learning...
