Use a Platonic solids worksheet to record the number of faces, edges, and vertices of five polyhedra whose faces, edges, and vertices are all identical. For each figure, learners write a proof of Euler's formula (F+V=E+2). They create a...

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Use this volume of solids lesson to have learners find the surface area and volume of cylinders, pyramids, and prisms. They place cubes inside three-dimensional figures to determine the volume. Worksheets and answers are provided.

Young scholars build models of the three major types of volcanoes and see how a volcano's shape is related to the type of material it erupts. As a class, they observe a demonstration that simulates the nature of two volcanic materials:...

Students understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

In need of some dot paper for your next geometry lesson? Then look no further. This simple template allows you to maintain a classroom supply of this special paper for whenever the need arises.

First graders use two-dimensional and three-dimensional media and techniques to communicate ideas, experiences, and stories in works of art. They use media and tools in a safe and responsible manner

Students examine new shape possibilities by combining two and four triangles using manipulatives.

Students take a 2 dimensional drawing and make it into a 3 dimensional form. In this art lesson plan, students base their work off of Keith Haring, and view slides and a video of other 3D art.

Students watch a video and slides to view Keith Haring's work of 3 dimensional forms based on 2 dimensional imagery. In this 3 dimensional forms lesson plan, students analyze symbols and discuss lines, sound, movement, and emotions.

Learners explore pyramids. In this math instructional activity, students discuss where they have seen examples of pyramids. Learners classify pyramids as three-dimensional figures and identify their attributes.

Students identify and explore the attributes of polygons. They design and create a quilt square using polygons, and produce a class quilt.

Students use specific dimensions to create a box. In this geometry lesson plan, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Students investigate measurement through the use of literature through this series of lessons.

Learners recognize, describe, and perform transformations (rotation/turn, reflection/flip, and translation/slide) on two dimensional shapes.

Third graders explore vocabulary associated with three dimensional figures.  For this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with describing two...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...

Play a coordinates game to encourage collaborative learning and grid use! Learners plot points on grids and play a game that challenges them to locate a specific point on a coordinate grid by using horizontal and vertical movements.

Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

Students explore geometry by participating in a shape identification activity. In this figure dimensions lesson, students identify the difference between 2 and 3 dimensional shapes by their vertices and faces. Students examine blocks in...

Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

In order to better understand how to locate a plane of symmetry in 3-dimensional objects, learners create a dance. The class reviews dance and math symmetry, then they practice making symmetrical shapes and movements with a partner....
