Surface Area and Measuring
Tenth graders explore volume and surface area through percentages. In this geometry lesson, 10th graders analyze the surface area of two and three dimensional shapes, then use percents and ratio to compare the two.

My Treehouse
If you could build your own treehouse, what would it look like? Using a piece of contemporary art as inspiration, learners draw their own treehouses and add geometric and organic shapes. The activity touches on Visual Thinking Strategies...
Curated OER
Sort it Out
Students identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and...

Opening A Cube
Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
Curated OER
Landscape Book
Students create a three-dimensional book about landscapes. They must show their understanding of shape, color and balance.
Curated OER
2-D Geometry
Third graders describe and compare attributes of two-dimensional shapes. They explain geometric terms, angles and shapes. Students demonstrate each vocabulary word with their body and they mirror the body positions associated with each...

Grade 2: Roll or Slide?
Second graders organize solids into categories, depending upon whether they will roll, slide or do both on a home made ramp. Students describe and compare attributes of three-dimensional geometric solids.
Curated OER
Tetrominoes Cover-Up
Third graders compare and contrast the attributes of two-dimensional shapes. Using a tetrominoes game, they create two-dimensional shapes to cover up a game board. At the conclusion of the game, 3rd graders discuss the patterns they...
Curated OER
Third Grade Geometry
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...

Geometry: Volume
In this geometry activity, 6th graders study comprehensive facts pertaining to volume and measurement of geometric, three-dimensional figures. Students solve for 59 problems showing their work.
Curated OER
Dimension in Art
Third graders consider space and the techniques artists use to create three-dimensionality within a painting or drawing. They examine works by Millet, Bruegel and Demuth and then create original drawings that explore the effects of...
Curated OER
Polygon Shapes
In this polygon worksheet, students study the various shapes and then name each of the two-dimensional shapes. Students write the shape names on the provided lines.
Curated OER
Drawing Figures
Third graders draw shapes that are congruent. In this congruency lesson, 3rd graders use grid paper to draw letters and figures and their congruent partners. They complete a worksheet while working in a whole class setting with the...

Geo Jammin' - Day 2, Lesson 5: Eeny, Meeny, Miney, Mo
Learners, in groups, use song lyrics and math to descrie two and three dimensional shapes.
Curated OER
Perimeter All Around
Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.
Curated OER
Shape Hunt
Young scholars photograph shapes around their school and create a shape movie. In this shape hunting lesson, students recognize shapes in a shape hunt. Young scholars can identify the shapes recorded by others in the class.
Curated OER
If I Had a Robot
Learners study writing. In this creative writing lesson, students write a story about having a robot and make a three-dimensional robot to accompany their writing.
Curated OER
Basic Right Triangles
Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...
Curated OER
Symmetry in Relief
Students explore radial symmetry. In this 3 dimensional art and geometry lesson, students identify examples of radial symmetry in everyday objects. Students create an imprint using radial symmetry on clay tiles.
Curated OER
Geo Jammin'
Pupils compare and contrast related two- and three-dimensional shapes, and complete a Venn diagram illustrating the attributes of each. Using a poem pattern from another instructional activity, students use data from the diagram to write...
Curated OER
Create A Map!
Students examine two- and three-dimensional shapes, and discuss map skills and attributes. They plan and create their own school campus maps using pre-cut building site shapes.
Curated OER
Pyramids & Prisms: Guler's Formula
Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the activity, they use the shapes they made and...
