Area and Perimeter of Geometric Shapes
Fifth graders determine how to calculate the perimeter and area of given geometric shapes. They use specific shapes to create a picture using a software program. They determine the area and perimeter of the shapes used in the picture.
Curated OER
Polarization Of Light
Students discover that polarization filters block incoming light from passing through when filters are positioned perpendicularly to each other. They explore some of the uses of polarization filters within our society.
Curated OER
Inscribed Angles
Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.
