Paper Folding to Make Cubes
Examine patterns of figures composed of six-squares and predict which of the twenty presented could be folded to make a cube. They then fold large-scale patterns of these figures to confirm their hunches.

My Abstraction
What makes a color warm, and what makes a color cool? Explore colors and abstract art through an observation activity and an art assignment. Learners look at images and talk about colors before making their own compositions with...
Curated OER
Shapes (Geometric)
Second graders explore geometric shapes. For this lesson about geometry, 2nd graders create their own vest using geometric shapes. Students work with a partner and fit their partner for the vest they design. Students understand geometric...
Curated OER
What's My Rule for Sorting?
Learners view objects sorted by one characteristic and name that characteristic. In this sorting rule lesson, students explore to find a new characteristic and write a description of that rule. In early grades the rule might...
Curated OER
Learning about Shapes with Tangrams and the Net
Students use tangrams, student literature, and Websites to explore shapes.
Curated OER
Artistic Angles
Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...
Curated OER
Volume and Surface Area: Which Is More?
Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...
Curated OER
Geometry and Quilting
Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...
Curated OER
Edible Geometry
Learners examine a chart that lists the main characteristics of polygons and 3 dimensional figures. They make examples of the polygons and figures using pretzels and gum drops showing how the gum drops are vertices and the pretzels are...
Curated OER
The Amazing Inch and Measuring Up!
Fifth graders study the metric and customary systems of measuring length with rulers, meter / yardsticks, and tape measures. They determine area of polygons and surface area and volume of three-dimensional shapes. They list as many...
Curated OER
Water Treatment Plant Tour
Young scholars define vocabulary related to geometry and calculate the volume. In this geometry lesson, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...
Curated OER
Geometry Flip Book
Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
Curated OER
Relating Space and Plane Shapes
In this mathematics worksheet, 1st graders identify which object in an illustration has a flat side the same shape as the box shown. Then they look at other shapes and identify the ones with a flat side, if any.
Curated OER
A Sphere and Its Net
Young scholars identify and sketch the nets for sphere. In this geometry lesson, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.
Curated OER
Yummy Shapes
Students explore space shapes learning about edges, corners, and faces. They enjoy shape soup as a culminating activity.
Curated OER
Symmetry of Flags
Students explore, examine and study the symmetry of the flags of individual countries in the EU. They identify and describe the reflection and rotation symmetries of two-dimensional shapes and assess how symmetry changes with respect to...
