Curated OER
Sketching Prisms
Students sketch and create nets of different polygons.In this geometry lesson, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.
Curated OER
Measuring Supporting Structures
Students calculate the volume of the Pantheon's columns and estimate changes in weight given different parameters.
Curated OER
Let the Light Shine Through!
Students display knowledge of line of symmetry by designing a geometric stained glass window pattern.
Curated OER
The Mandelbrot Set
Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.
Curated OER
Tessellating Tiles
Second graders Make, name and describe, using their own language and the language of geometry, everyday shapes and objects. They create and talk about geometric patterns which repeat (show translation), or which have rotational or...

Geo Jammin' - Day 5, Lesson 17: Geo Sakes Alive!
Second graders, given geometric instructions, try to create their own Geo George puppet.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The activity and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
Manipulative Mania
Learners explore tangram vocabulary and tangram designs, creating an art design that contains various geometric parts. They complete a checklist titled, Important Thing About a Quilt Design.
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.
Curated OER
Area, Surface, and Volume
Ninth graders demonstrate application of area, surface, and volume. They apply formulas to a model of the classroom so they can determine the volume and surface area of the classroom.
Curated OER
Designing a Quilt Pattern
Students create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.
Curated OER
Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
Curated OER
Distortion Unleashed
Students view examples of man-made structures and create a building that matches the style. Using the internet, they research the style of Frank Lloyd Wright and create plans for creating their own community. They use a painting of...
Curated OER
Introduction to Fractals: Infinity, Self-Similarity and Recursion
Young scholars think about several of the concepts from fractals, including recursion and self similarity. They use mathematical concepts of line segments, perimeter, area and infinity are used, and skill at pattern recognition is...
Curated OER
Learning About Guatemala Through Its Kites
Students are introduced to Guatemala and to the tradition of giant kites. They decorate the kite sail and construct the kite. Students identifies possible causal factors contributing to given historical events.
