Curated OER
Area and Perimeter
Students participate in a hands-on activity that shows the independence of perimeter and area for simple irregular figures.
Curated OER
Pape's Theorems
In this math worksheet, students find the length of the side of a regular hexagon whose area is numerically equal to its perimeter.
Mathematics Assessment Project
Evaluating Statements About Length and Area
Class members complete an assessment task by identifying whether statements about triangles and quadrilaterals are always true, sometimes true, or never true. They then participate in a sorting activity with the same objective.
Curated OER
Infinite Secrets
Learners duplicate the method that Archimedes used to estimate the value of pi. They complete a data table and find the approximate values of pi for three sets of polygons.
Curated OER
Geometry in Tessellations
Pupils examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Pupils experiment with the area and perimeter of polygons. Students analyze...
Curated OER
A Cylinder Workshop
Young scholars work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.
Curated OER
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
Octagon Lesson Plan
Students investigate octagons using words and shapes. In this geometry lesson plan, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.
Curated OER
Geometry: Area Project
Sixth graders identify and use area formulas for finding the area of geometric shapes.
Curated OER
Geometry, Measurement & Reasoning
Students measure prisms and determine their volume. For this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...
