After understanding that the volume of a unit cube is one cubic centimeter, math masters determine the volume of four larger rectangular shapes. Then they take the challenge to figure out the volume of seven irregular, cube-containing...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

This resource was written for the younger math learner, but finding the volume of an irregular solid is also a problem for algebra and geometry students. Based on Archimedes’ Principle, one can calculate the volume of a stone by...

High schoolers explore displacement. In this displacement and density lesson, pupils find the volume of irregular shaped objects. Afterward, they determine the volume of containers. They compute the amount of water displacement.

Students engage in a instructional activity that is concerned with finding the volume of a solid. They investigate and describe the characteristics of a favorite food and identify it as metal or non-metal. The instructional activity...

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

What does popcorn have to do with math?  Seventh grade mathematicians are provided an opportunity to develop a conceptual understanding of the formula for volume and to use it as a tool to solve problems. The lesson begins with a...

Investigate the volume of irregular figures in an inquiry-based exercise. Presented with an irregularly shaped box filled with water, learners must predict the level of water when it is tipped on its side. The class can divide...

Fifth graders find the area and volume of buildings. In this architecture activity, 5th graders look at the drawings of three historic Tennessee buildings. They use these to help find the area and volume of the building. 

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Young geometers need a clear understanding of perimeter, volume, and area. This lesson plan provides a worksheet to help small groups of learners to calculate various measurements of objects and choose the proper units for measurement....

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.

A set of 49 math vocabulary cards ranges from angle to irregular polygon to parallel lines. Each sheet contains two cards: one with the word printed in bold text and the other with the definition.

Students explore math functions by completing math equation worksheets. In this inequality instructional activity, students define a list of math terms and discuss the difference between an equation and inequality. Students utilize a...

Fifth graders examine patterns and relate to equations to solve math problems.  In this patterns lesson, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Students explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Students identify different woods based on their density. In this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of wood...

This site is a wonderful exercise for students with a Calculus base. The site gives an interactive drawing of a vase where the measurements of the diameter of the vase are at any point. The student then finds the volume using calculus....

Find the volume of irregular 3D figures made up of unit cubes by dividing the figures into rectangular prisms and finding the volume of each part. Students receive immediate feedback and have the opportunity to try questions repeatedly,...

The purpose of this fourth task in a series of four is to find the volume of an irregular 3D solid by using Archimedes' Principle. Students must calculate the volume of the displaced water in a rectangular prism tank in order to solve...
