History and the Approximations of pi
Middle schoolers investigate Pi. In this mathematics lesson, learners discuss the history of Pi and determine how the approximation of Pi was discovered.
Curated OER
Word Problems: Geometry
Students solve word problems by using basic geometry. In this geometry lesson, students use geometric formulas to find the perimeter, area, and volume of objects. Students complete a worksheet.
Curated OER
Karen's Tiles
Students investigate how perimeter changes as area changes to see the relation between area and perimeter for similar shapes. They then students answer the question if the area of the rectangle increase, does its perimeter have to increase?
Curated OER
What a Square
Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.
Curated OER
The Internet Pizza Server - Pizza Simulation
Learners simulate going to a pizza restaurant, ordering a pizza, and determining whether a small, medium, large, or family size pizza is a "better-buy." Students calculate the price/per/topping and determine whether this price is "fair"

Year Book Page Special Shape Collage
Students design a collage of pictures for a yearbook that make a shape. They determine the area of the shape and the price of putting the collage in the yearbook.
Curated OER
"Slice of Pi with Neo-Excel"
Students explore diameter, radius, and circumference. They define radius, diameter, and circumference on an online dictionary, identify objects in the room with a radius and a diameter, and calculate the radius and diameter of various...
Curated OER
Sectors of Pizza
Students identify the properties of a circle. In this geometry activity, students relate properties of diameter to sections of a pizza. They calculate the measure of an arc and missing angles.
Curated OER
Pi Day
Ninth graders explore the concept of pi in preparation for developing a project for pi day. They examine direct variation, the history of pi, circle circumference and arc length, area and sector area and then consider how these concepts...
Curated OER
Light Beam
Students measure and convert between units. In this geometry lesson plan, students investigate through measurements of distances. They relate the properties of circle to solving problems with radius, diameter and area.
