K–12 teaching and learning · from the UNC School of Education

Goal 1

Number and Operations - The learner will perform operations with real numbers to solve problems.

Objective 1.02

Use length, area, and volume of geometric figures to solve problems. Include arc length, area of sectors of circles; lateral area, surface area, and volume of three-dimensional figures; and perimeter, area, and volume of composite figures.

Resources aligned to this objective

Edible geometry
Students will use food to demonstrate their understanding of the sectors and arc lengths in a circle.

Relationships between reflections and symmetry
In this lesson, one of a multi-part unit from Illuminations, students learn the properties of designs that have bilateral symmetry. They also make their own designs and investigate dihedral symmetry. (Learn more)
