This interactive exercise focuses on determining probabilities associated with repeated coin tosses and building tree diagrams to take math out of the classroom and into the real world.

In this lesson, students will watch videos about shapes and identify shapes in their environment and in art. Links to the videos are at the bottom of the lesson overview, other material links are also provided.

Two and three-dimensional geometric shape are explored in these exercises. Each activity has teacher notes, activity instructions, and a worksheet when necessary.

In this Five E's AMSTI lesson, students discover relationships between shapes. Students discover multiple ways to combine shapes to fill the area of a given shape using real and virtual pattern blocks, and share their solutions with...

Students make a series of geometric drawings of points, obtuse angles, rays, polygons, and the like. Each child is given one but not allowed to show anyone else. The drawing is then taped to the back of the child in front of them. The...

Definition of shape as it applies to the visual arts with examples by Duchamp and McKnight. Links to definitions of other elements of art.

Use this applet to sort shapes according to their properties using Venn diagrams.

Explore two and three dimensional geometric shapes by creating shapes based on descriptions.

Mathematicians in ancient Greece were amazed by mathematical patterns, and wanted to explore and explain them. They began to study mathematics just "for fun" without a specific application in mind. One of these mathematicians, Thales of...

In this activity, students will identify the characteristics of a quadrilateral. Students will have a chance categorize quadrilaterals into subgroups such as squares, rhombuses, rectangles, and nonregular quadrilaterals. This activity...

Use this site to practice identifying shapes, colors, and animals with these interactive games.

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

The purpose of this activity is to demonstrate how drag affects falling objects. Students will make a variety of shapes out of paper and see how size and shape affects the speed with which their paper shapes fall. They will also be able...

In this lesson plan students will learn about reflection of light using soap bubbles.

This tutorial explains the concept of surface area, and then goes through multiple shapes offering the specific surface area formula for each one.

Using an engaging approach, this lesson requires students to record the volume of cylinders as a function of the radius. Students will construct and measure the volume of several cylinders and then begin comparing these shapes.

Use this lesson plan to help students learn about cylinders. Students will be creating cylinders, and comparing them and their capacity. This engaging, hands-on lesson will hold student interest and be very beneficial to student learning.

[Free Registration/Login Required] This is a formative assessment task where students are asked to use geometric solids to model each of four tent shapes on a worksheet and use mathematical language to describe them. Samples of student...

[Free Registration/Login may be required to access all resource tools.] This concept introduces geometric rotations.

Eighth graders are presented with a tile pattern showing an apparent square surrounded by four octagons. They are asked to answer a question about congruency and angle measurements, as well as prove that the interior shape is really a...

In this task, learners are given the dimensions of a soda can and are asked to estimate its thickness. They must first find the surface area and the volume of aluminum. Aligns with G-MG.A.1 and G-MG.A.2.

Play a matching game with different representations of equivalent items.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

Why are most manhole covers round? Sure it makes them easy to roll, and slide into place in any alignment. But there's another, more compelling reason, involving a peculiar geometric property of circles and other shapes. Marc Chamberland...
