Learners investigate spherical geometry using a globe and an apple. In this spherical geometry lesson plan, students translate Euclidean geometry terms to spherical geometry terms using a globe. They answer 3 questions about spherical...

Learners explore area and perimeter through coordinate geometry using student literature, hands-on manipulatives, and the Internet.

Students measure their body. In this measurement lesson, students use a string to measure their height and the circumference of their head. They record this information on the worksheet provided and answer questions as a group. 

Students explore measurements and geometric formulas. In this geometry lesson, students investigate pi as it relates to geometry. They collect data and use a chart to organize the data.

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Junior geometers use hands-on manipulatives to explore and describe the properties and attributes of a fundamental polygon, the triangle. They learn different kinds of angles and their measurements. This well-written lesson plan provides...

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...

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...

Students use their county's information page to gather information about their community. Using the information, they create graphs from the tables provided and interpret the data. They write a paragraph showing their interpretation of...
