Getting Familiar with Fractals
Pupils use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.
Curated OER
Cones, Cylinders, Spheres
Young scholars classify polygons by name and shape. In this geometry lesson, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
Curated OER
Populations Lab - Exponential Graphing
Ninth graders investigate the application of populations that exists in one's everyday environment, in order to develop an understanding of how mathematics is a key component in the understanding of population dynamics.
Curated OER
Pyramids- Slant Height and Altitude
Students calculate the height and altitude of a pyramid. In this geometry lesson, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.
Curated OER
Similar Triangles
Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.
Curated OER
Area graphics for 7th graders
Students randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.

Orthographic Drawings
Learners investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.
Curated OER
Geometry and Measurement
Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Paper Gliders
Sixth graders study friction and drag. For this science lesson, 6th graders use different models of gliders and test to see which of the gliders fly the farthest. Students analyze their data and construct a graph.
Curated OER
Copy Cat
Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
