Curated OER
Area of Combined Shapes - Turtle Combo
Students graph polygons using the name and number of sides. In this geometry lesson plan, students identify the formula to calculate the area and perimeter of polygons. They relate the formula to different polygons and shapes.
Curated OER
Pattern Matching
First graders examine how to determine the lines of symmetry in pictures, shapes, and patterns by completing the lessons in this unit. They make patterns that show a line of symmetry and describe it using their own language.

Lesson Exchange: Polygons (Middle, Mathematics)
Learners 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.

Transforming Triangles
Sixth graders examine how to graph translations (slides) and reflections (flips) on a coordinate plane. They practice the slides and flips kinesthetically and apply it to a worksheet working with triangles.
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...

Using the Variation Approach
Young scholars explore and explain geometrical applications, and how to apply these applications to real life.
Curated OER
Copycats
Third graders describe the features of 2 and 3 dimensional objects and use the language of geometry. They design and make a pattern which involves translation, reflection or rotation.
Curated OER
Precision Tools
Students 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...

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.
