Properties and Attributes of Polygons
In this geometry worksheet, 10th graders determine if a polygon is convex or concave and apply the polygon Angle sum theorem and the polygon exterior angle sum theorem to determine the measures of interior and exterior angles of a...
Curated OER
Powerful Polygons
Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...
Curated OER
Teaching Polygons using Technology
Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...
Curated OER
Identifying Angles
After identifying angles (acute, obtuse, right) during a math or science lesson, 4th graders will use the computer to stamp pictures in the correct category using KidPix computer software.
Curated OER
An Introduction to Quadrilaterals
Young scholars explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.
Curated OER
Shapes with Sticks
Third graders investigate three dimensional shapes. They examine a variety of shapes and the relationship between the number of faces, edges, and vertices. Students determine Euler's formula and they create a variety of three dimensional...

Build a Weather Vane
Students construct a weather vane using their knowledge of some geometric shapes. In this weather lesson, students work in pairs to create a weather vane in order to measure wind direction. Students follow precise directions to ensure...
Curated OER
Interior and Exterior Angles of Polygons
Young scholars identify interior and exterior angles of polygons. In this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.
Curated OER
Translations, Reflections, and Rotations
Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.
Curated OER
Surface Area with Polydrons
Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...
Curated OER
Ship Shape
Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.
Curated OER
Meet the Polygon Family
Fourth graders investigate regular polygons. In this regular polygon instructional activity, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
