Course Description

From the CTY Summer Catalog:

Spatial understanding is necessary for interpreting, understanding, and appreciating our inherently geometric world. Many tasks a person performs—whether designing a treehouse, solving a jigsaw puzzle, or laying out a garden—require good spatial reasoning abilities.

Through interactive investigation and discussion, students discover mathematical relationships such as congruence, symmetry, and reflection. They learn geometric formulas to calculate area, surface area, perimeter, circumference, and volume and are asked to explain their findings using geometric terminology. Students explore the geometric properties of regular polygons and create their own polyhedra using paper-folding techniques. Tessellations, similarity, measurement, polygons, polyhedra, and curved shapes are investigated through two- and three-dimensional drawings and physical models. Students also construct classic geometric figures using a straight edge and a compass as they are introduced to the essential elements of geometry. Through explorations and demonstrations, students leave this course with greater spatial sense as well as a solid understanding of foundational geometric concepts.

Students must have completed grades: 3 or 4
