Tessellations: Geometry and Symmetry
Students examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling to...
Mathematics Vision Project
Geometric Figures
Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...
Curated OER
Product of Chord Segments
Students creating chords intersection using circles. For this geometry lesson, students create visuals of chords ad their properties using Cabri technology. They measure the chords and explore the relationship among chords.
Mathematics Vision Project
Circles: A Geometric Perspective
Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...
Willow Tree
Perimeter of Common Geometric Figures
Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...
Curated OER
Cover the Triangle
Students explore geometric shapes using pattern blocks. They use specific shapes to fill in triangles, color-in their solutions, and discuss the results with a partner.
Curated OER
Dodecahedron
In this dodecahedron instructional activity, students build a model of a dodecahedron. The pattern for this shape is made up of twelve pentagons. This is a instructional activity generator, and the teacher can choose if a sample of the...

Find Someone
Your class will participate in a series of math vocabulary activities to learn about parallel lines. They find people using a math list and connect math words in the context of sentences. They also read the math words in the example...
Curated OER
Geometry Scavenger Hunt
Pupils use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Curated OER
Geometric Collages
Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

Applied Science - Science and Math Lab
Students investigate topology. In this Applied Science lesson students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.
Curated OER
Totally Tessellations!
Eighth graders investigate the concept of tessellations and transformations. They create patterns to demonstrate and practice the skill. Students write a description of the pattern for others to interpret. The pattern is assessed...
Curated OER
And The Twelfth One Is
Ninth graders play guess my shape (either describe or use a feely bag to introduce the 3 shapes in the problem.) As they are identified put them in an order as shown in the problem. As the students work on the problem in pairs teacher...
