Investigating the Sierpinski Triangle
Students solve and analyze the sierpinski's triangle. In this geometry lesson, students identify properties and theorem of triangles. They solve problems involving angles and sides of triangles.
Curated OER
The Sierpinski Triangle
Students investigate the Sierpinski triangle. In this geometry instructional activity, students define fractal curves and its relationship to triangles. They identify repeating sequences and relate it to fractals.
Curated OER
The Flat Earth
Students differentiate between different planes. In this geometry lesson, students differentiate between a plane and a sphere. They discuss the Great Circle, Geodesic and Lune as it relates to the earth.
Curated OER
Sketching Spheres
Young scholars investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.
