Thinking in the Three Dimensions
Discover different dimensions with paper folding. Pupils first read about zero, one, two, and three dimensions, and then learn about the fourth dimension, time. They then use origami to create models of shapes in three dimensions and use...

Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.

Finding the Area Under A Curve with Random Probability
Students explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

Using Concept Maps to Design 3D Spheres
Young scholars create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.
Curated OER
Cones, Cylinders, Spheres
Students classify polygons by name and shape. In this geometry activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
Curated OER
Examining Geometric Solids
Students explore geometry by completing a math worksheet in class. In this shape identification instructional activity, students identify the characteristics associated with 15 solid geometric shapes. Students identify patterns between...
Curated OER
A Sphere and Its Net
Students identify and sketch the nets for sphere. In this geometry instructional activity, students differentiate between two and three dimensional shapes. They find the surface area of each sphere.
Curated OER
Geometry and Measurement
Learners 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. Learners use pegboards and string to create more...

ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
