Using Concept Maps to Design 3D Spheres
Students 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
Mass and Space
Students view a variety of sculptures analyzing how space and mass interact, and how sculptors make choices about mass and space to express meaning in their art. They make small three-dimensional sketches experimenting with mass and space.
Curated OER
Surface Area of Cones
Students find the surface area of cones. In this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.
