The Castle
Students build a castle to Ravi's design using the cubes. Students then make an original model of a solid object from diagrams which show views from the top, front, side and back. Students describe the reflection of rotational symmetry...
Curated OER
Miras, Mirrors, and Kaleidoscopes!
Students use hands-on activities to explore transformations. They view a video segment that demonstrate how M. C. Escher employed geometry and transformations to create so many of his famous drawings.
Curated OER
Fractal and the Dragon Curve
Students explore Fractal designs. In this geometry lesson, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.
Curated OER
Identifying Transformations
In this identifying transformations worksheet, 3rd graders look at three figures and choose reflected, rotated or translated to indicate how it has been transformed.
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...
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
Technology Integrated Lesson
Students investigate symmetry in the real world. In this geometry lesson, students inter-relate math and technology. They create and name a variety of polygons.
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...

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
Transformation Trio
Students identify the transformation and rotation of polygons. In this geometry lesson, students use picture to perform rotation, reflection and transformation. They identify the coordinate points of the new transformation.
Curated OER
Tangram Geometry
Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.
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...
