Plane and Solid Figures
Young scholars define a plane and a solid shape. In this geometry lesson, students compare and contrast different geometric shapes as they relate to solids. They name the geometric solids based on their sides and edges.
Curated OER
Solid Figures
Students investigate solids. In this geometry instructional activity, students use toothpicks and gum drops to solve problems. They create visuals to help them see what is happening to the shapes.
Curated OER
Volume of Cylinders
Middle and high schoolers calculate the volume of cylinders. In this geometry lesson, learners differentiate between rectangular prisms and cylinders. They use the correct formula to solve for each solid.

Congruence with Robot Gobot
Students identify the properties of solids and polygons. In this geometry lesson, students identify the different measurements of a triangle. They use congruence parts and theorem to prove their answer.
Curated OER
Surface Area of Prisms
Young scholars calculate the surface area of different prisms. In this geometry lesson, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

The Value of Volume
Students measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.
Curated OER
Polyominoes
In this dominoes instructional activity, students solve a word problem involving different ways to put dominoes together. Students complete 1 complicated higher order thinking problem.
Curated OER
Faces, Vertices, Edges
Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Why Doesn't SSA Work?
Students investigate the relationship between angles and their sides. In this geometry lesson, students prove why SSA does not work as a true angle side relationship theorem.
Curated OER
Euler Characteristic
Pupils identify the different properties of Euler's Characteristics. In this geometry lesson, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.
