If helps in exploring, describing, and understanding the world in which we live. This strand includes objectives that require students to investigate, experiment, and explore with physical materials, drawings, and computers.
Students also communicate the results of their investigations with verbal descriptions or drawings.
The K-8 part of the strand is designed to help children develop spatial sense and develop facility with the language of geometry before the formal study of geometry takes place at the secondary level. Something more than a superficial study of geometric shapes and terminology is essential from the earliest school experience. The strand begins with recognition of whole shapes in the classroom and in the environment and proceeds through analysis of properties of shapes and their transformations to the expression of geometric properties algebraically. While informal proof or validation is used in the early grades, more formal proof is delayed until the high school grades. 2. manipulate, color, fold, and create simple geometric shapes.
