Moving On: Octagoning the Circle
Students explore circles through the use of octagons. They inscribe a circle in a regular octagon and find the area and perimeter of the hexagon with respect to the radius of the circle. Students present their findings to the class.
Curated OER
Seeing Shapes
Learners study a variety of geometric shapes by taking pictures of items representing the shapes with a digital camera. They identify the shapes by using software to paint on the image.
