Can a Geometric Mean be Nice?
For this Geometry instructional (work)sheet, learners are instructed on how to find the geometric mean. Students are then shown how the geometric mean is applied to proving similar triangles.
Curated OER
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.

Next Generation Spacecraft - Orion
Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.
Curated OER
Perimeter and Area
In this perimeter and area worksheet, 9th graders solve 17 various types of problems, mostly word problems related to determining the area or perimeter of a geometric shape. They also determine the area and perimeter of shaded portions...
