Square Circles
Students analyze and demonstrate how a circle can be measured in square units and examine how diameter, circumference and radius are related.
Curated OER
THE AREA OF A CIRCLE
Students examine the relationship between circumference and diameter and how to use the formula to find the area of a circle. In this circle lesson plan students divide into groups and complete an activity.

Surface Area and Volume of a Cylinder
Seventh graders find the surface area and volume of a cylinder. In this area and volume instructional activity, 7th graders complete several activities to learn the volume and surface area of cylinders.
Curated OER
Discovering Pi
Define terminology related to a circle. Practice accuracy in measuring and then create a spreadsheet based on data collected from solving for parts of a circle. Groups can have fun analyzing their data as it relates to Pi.
