Technology Integrated Lesson
Students investigate symmetry in the real world. In this geometry lesson, students inter-relate math and technology. They create and name a variety of polygons.
Curated OER
More Prisms/Nets
Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.
Curated OER
Surface Area of Pyramids
Students identify the surface area of pyramids and other polygons. For this geometry lesson, students find the different measurements for the different parts of a polygon. They use the surface area formula to solve for the surface...
