Geo Jammin' By DeSign - Day 5, Lesson 25: Geo Jungle
Students search the school grounds for examples of symmetry in nature. They bring examples back to the classroom and write about them.
Curated OER
Reflecting a Rectangle Over a Diagonal
Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.
Mathematics Vision Project
Module 6: Congruence, Construction, and Proof
Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This unit...
Curated OER
Reflections and Equilateral Triangles
Your learners collaboratively find the lines of symmetry in an equilateral triangle using rigid transformations and symmetry. Through congruence proofs they show that they understand congruence in terms of rigid motions as they prove...
Illustrative Mathematics
Reflections and Isosceles Triangles
Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...
Curated OER
Mathematics in Art?
Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...
Curated OER
Geometry History Lesson
Tenth graders investigate the early history of geometry. In this geometry lesson, 10th graders investigate translations, rotations, and reflections. They also solve problems with line of symmetry and rotational symmetry while reviewing...
Curated OER
Geometrically Artistic/Artistically Geomtric
Students identify the two-dimensional geometric shapes Lowrey utilized in the painting Untitled. Students compare the two-dimensional shapes in terms of equivalent fractions, congruency, symmetry and asymmetry. Students create their own...
Curated OER
The Very Busy Spider-Pattern
Students explore two- and three-dimensional shapes. In this very busy spider lesson, students read the story and then create a spider web pattern of their own. The webs must use a symmetrical pattern. Additional activities for patterns...
Curated OER
Radial Design Mandala
Learners design original radial art designs.In this radial design lesson, students use compasses and a nature inspired idea to create radial art. Learners understand the use of symmetry, balance and design shapes in continual patterns....
Curated OER
Terrific Tessellations
Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
Curated OER
Sequencing Worksheet
In this patterns and sequencing activity, 9th graders complete 30 math problems that involve patterns and rules. Students must read information as they work through the math problems.
Curated OER
Spiders' Wheel
Students engage in a lesson which reinforces the concepts of clockwise and anti-clockwise rotation, while developing an understanding that angles are measured in degrees. They utilize a mathematics educational program to gain practice.
Curated OER
Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.
Curated OER
Geo Jammin' By DeSign - Day 1, Lesson 1: Math in Motion
Second graders, through large screen monitor, study geometric design. They participate in a diagnostic assessment in which they use pnecils, scissors and paste.
Curated OER
Geo Jammin' By DeSign - Day 4, Lesson 22: Authentic Design
Students explore the complexity of handmade quilts and their designs by looking a real life samples.
Curated OER
Ge-Oh Boy, Oh Boy
Students listen to the book, Sam Johnson and the Blue Ribbon Quilt and discuss the art of quilting. They examine various symmetrical sewing designs, and identify reflection pieces, slides, and flips.
