Students create entries for the Architects of America contest, including a model of a futuristic structure, blueprints, a list of all plane and solid shapes in the structure, a persuasive argument paper that describes why the structure...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Fourth graders explore geometric properties and relationships in a two-dimensional work of art. They first search for and identify polygons in a Cubist painting and then use polygons to create their own Cubist portrait of a classmate.

Learners classify, flip, slide, and turn a quantity of quadrilaterals.

Students explore geometry by participating in a shape rotation experiment. For this symmetry lesson, students identify the term symmetry and a list of other geometry vocabulary. Students analyze shapes as they are turned 90 degrees and...

Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...

Students create a glossary of geometric terms while exploring tangram manipulatives.

Students search the school grounds for examples of symmetry in nature. They bring examples back to the classroom and write about them.
