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, students compare and contrast different geometric shapes as they relate to solids. They name the geometric solids based on their sides and edges.

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

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...

Junior geometers practice stating the names of different geometric shapes. They define and name the different shapes and compare and contrast shapes to one another. They also relate the shapes to objects in the real world.

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

Learners consider the rate of filling a cone in the 23rd installment of this instructional activity series. They analyze the volume of the cone at various heights and discover the rate of filling is not constant. The instructional...

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...

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

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...

Learners explore points, lines and planes as it relates to geometry. For 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 measure the perimeter and area of their polygons. In this geometry instructional activity, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side...

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.

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 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 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.

Second graders are introduced to circles, triangles and parallelograms. As a class, they create the shape with their bodies and are shown the shapes in their actual size. To end the lesson, they sketch each shape and identify their...

Students investigate the Pythagorean Theorem.  In 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...

Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the lesson, they use the shapes they made and...

Learners identify the different properties of Euler's Characteristics. For this geometry lesson, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.
