Transformations
Students draw on graph paper. In this geometry lesson, students review types of triangles and quadrilaterals. Students investigate geometric transformations, including translation, rotation and reflection. Students practice each...
Curated OER
Transforming Triangles
Sixth graders graph translations (slides) and reflections (flips) on a coordinate plane. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders write a paragraph telling...
Curated OER
Tiling the Plaza (Geometry)
Students make patterns with a variety of pattern blocks. Pupils experiment with making tile designs using only one shape by rotating that shape around a point. They enter a contest for creating the best tile design for the new plaza...
Curated OER
Measuring the Area of Polygons
Fourth graders use pattern blocks to explore areas of polygons. They explain that the answers to the area of the same polygon vary according to the units of measurement used. They visualize how different units of measurement can be used...
Curated OER
Downtown Landmarks: Geometry on Firstside
In this geometry worksheet, students outline at least one example of each of the eighteen geometry shapes and figures listed in the photograph Firstside.
Curated OER
Mira, Mira on the Wall: Reflections
Students investigate and perform reflections and symmetry. For this geometry lesson, students compare and contrast the relationship between reflections and symmetries.
Curated OER
Fold and Cut 2
Second graders make, name, and describe, using their own language and the language of geometry, everyday shapes and objects. They create and discuss geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Patterns: A Stitch in Time
Learners recognize shapes, designs and numbers that form patterns. Using their surroundings, they identify common patterns. They create their own patterns in various software programs and share them with the class.
Curated OER
Cracker Design
Students are presented with the following problem: A cracker manufacturer has been losing money and has to find a way to save her factory. They are given the task to design a new shape for the cracker manufacturer so that as little...
Curated OER
Symmetries in Quadrilateral Tilings
Students analyze symmetries of quadrilateral tilings and discover how various types of symmetries, used alone or in combination, can generate the same pattern in more than one way.
Curated OER
Map Making/Floor Plans/Map Reading
Students apply their knowledge of scale when mapping the classroom. They determine the use of a map legend and orient a map using a compass. They create the classroom maps using transfer graph paper.
Curated OER
Area of Combined Shapes - Turtle Combo
Pupils graph polygons using the name and number of sides. In this geometry lesson, students identify the formula to calculate the area and perimeter of polygons. They relate the formula to different polygons and shapes.
Curated OER
Lesson Exchange: Polygons (Middle, Mathematics)
Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Geo Jammin' By DeSign - Day 1, Lesson 2: Dancing Duo
Second graders and teachers identify geometric vocabulary word by searching a geometry website. They create a Quilt Word Wall using the geometry words.
Curated OER
Geo Jammin' By DeSign - Day 3, Lesson 15: The Quiltmaker's Gift
Learners listen to a read aloud of The Quiltmaker's Gift by Jeff Brumbeau finding examples of symmetry in the illustrations in the book.
Curated OER
Transformation: Reflection
Tenth graders identify and analyze appropriate key vocabulary terms associated with transformations and reflection. Students experience creating and recognizing reflection with hands-on manipulations. Students discover real-world...
Curated OER
Downtown Landmarks: geometry on Firstside
In this geometry learning exercise, students look at a picture of downtown landmarks and identify different shapes, lines, and more. Students identify 18 items.

Tetrominoes and Translations
Students explore geometry by participating in a pattern identification activity. In this tetrominoes lesson, students define the characteristics of congruent and symmetrical shapes. Students practice translating shapes across quadrants...
Curated OER
Using the Variation Approach
Pupils explore and explain geometrical applications, and how to apply these applications to real life.
Curated OER
Precision Tools
Learners discuss the appropriateness of using a specific tool to measure and define an object. After measuring the area of their classroom and the objects in it with the appropriate tools, they create a floor plan that makes the most...
Curated OER
Refining and Reasoning Behind Scale Drawings
Students discuss accuracy and the need for it in blueprints in order to create the final project. They further refine and perfect drawings as part of the school drawing project. Students create a blueprint for the new school building...
Curated OER
Geo Jammin' By Design: Listening for Patterns
Students listen to the teacher read a book and participate with guided questions. They discuss patterns and how they repeat, by looking at quilts. They design their own quilt block to create a class quilt.
Curated OER
Geo Jammin By Design: The Important Thing
Students brainstorm what they know about geometric terms and patterns. They identify symmetry, shapes and congruency. They create a book of symmetry.
