Curated OER
Octahedron
In this math worksheet, students develop cognitive and geometric abilities. They construct a paper model of a octahedron composed of eight triangular faces, six vertices and 12 edges.
Curated OER
Algebraic Processes And Its Connection To Geometry
Middle schoolers investigate the concept of polygons using a variety of activities. They explore the vocabulary of polygons by constructing a graphic organizer. Then students categorize the characteristics of several polygons and...
Curated OER
The Anti-Gravity Machine
Students examine physics by completing a bicycle experiment in class. In this gravity lesson, students measure the characteristics of different bicycles and compare their different race times. Students utilize a shoebox, pencil, tape,...
Curated OER
Building Big and Strong
Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.
Curated OER
Angle Exploration and Classification
Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.
