Symmetry and Geometric Shapes on Campus
Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not.

Identify Shapes and Matching Parts
Young scholars identify real world objects as shapes they have learned. In this 3-D shapes worksheet, students identify shapes such as a cube for a box, a sphere for a globe, and a cylinder for a soup can.
Curated OER
Shapes
Learners identify attributes of different geometric shapes. In this geometry lesson, students view a PowerPoint presentation on shapes and use attribute blocks to examine the corners and edges of each shape. Learners work together to...

Measurement: 2D and 3D
Students solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities include...

Get in Shape with Geometry
Using geoboards, computer programs, and hands-on manipulative materials, elementary schoolers engage in a study of two and three-dimensional geometric shapes. This instructional activity is chock full of good teaching ideas on the...
Charleston School District
Volume of Composite Shapes
It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of...
Curated OER
Dihedral Figures
Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.
Curated OER
Shapes: Art or Geometry
Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.

Geo Jammin' - Day 2, Lesson 4: Sing a Song of Shapes
Students learn five songs to define and develop understanding of the attributes of two- and three-dimensional figures and the meaning of mathematical terms. They classify objects as either two- or three-dimensional, through the use of...
Curated OER
Compare 2-D Shapes
Second graders examine the attributes of two-dimensional shapes. In this geometry lesson, 2nd graders play a game in order to identify two-dimensional shapes and to name them.
Curated OER
Shapes
Discuss the properties of 2D and 3D shapes in order to help learners understand the concept. Learners will participate in an interactive whiteboard lesson to develop understanding of 2D and 3D shapes.

Nets of 3-Dimensional Figures
In this nets learning exercise, students determine which figures will make given nets, then write the names of 4 given shapes. A reference web site is given for additional activities.
Curated OER
What a View!
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...
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
Curated OER
One Good Turn Deserves Another
Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.
Curated OER
Roll or Slide?
Students explore models of three-dimensional shapes. In this geometric shapes instructional activity, students use hands-on manipulatives to explore three-dimensional shapes. Students predict whether each shape will roll or slide.
Curated OER
Give It a Whirl
Learners examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.
It's About Time
Center of Mass
Lead your class on an exploration as they locate the center of mass in several oddly shaped two-dimensional objects they create from their imaginations. Pupils also determine the location of the center of mass in three-dimensional...

The Global Grapefruit - Representing a 3-Dimensional Globe on a 2-Dimensional Map
Students compare and contrast world maps and globes. They convert a 3-dimensional globe to a 2-dimensional map. They are introduced to the Mercator map projection. They observe map distortions of shape, area, distance, directions and angle.
Curated OER
Marshmallow Figures
Students 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...
