Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

Students define a plane and a solid shape. In this geometry lesson plan, students compare and contrast different geometric shapes as they relate to solids. They name the geometric solids based on their sides and edges.

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Students identify different types of polygons. In this geometry instructional activity, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

Sixth graders explore three-dimensional objects. Using various objects found in the classroom, they identify faces, edges, and vertices of objects. Students create their own objects. They describe the polydron, telling the faces,...

Students find the volume of spheres. In this geometry instructional activity, students measure and derive the formula for each shape and solid. They use the correct terminology and units when solving these problems.

Students explore polygons and their uses in careers. They also discover polygons shapes in manmade objects and nature. They use their acquired knowledge to construct a strong structure using polygon shapes.

Fourth graders find the volume of solids. In groups, 4th graders use spinners to determine the dimensions of solids. They construct the shapes, creating a model of the figure Students count the cubes in the model to determine the...

Middle and high schoolers calculate the volume of cylinders. They measure the height, radius and diameter of cylinders. Following given formulas, students calculate the area and volume of the cylinder. They compare cylinders and predict...

Students analyze different polygons by shapes and sides. For this geometry lesson, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...

Students explore points, lines and planes as it relates to geometry. In this geometry lesson, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Students calculate the surface area and volume of shapes. In this geometry lesson, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales and shapes.

Students investigate the Pythagorean Theorem.  For this seventh through twelfth grade geometery lesson, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right...

Students calculate the sum of the angles of a polygon. In this geometry lesson, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.

Fifth graders record measurements and calculate the volume. They select and use appropriate units and procedures to measure volume # use tools such as technology to solve problems
