Mathematics, level: Elementary
Posted Tue Jan 31 18:36:28 PST 2006 by Erin Coy (erincoy@msn.com).
Dacusville Elementary School, Easley, South Carolina USA
Activity Time: 45 minutes
Concepts Taught: Measurement/Spacial/Geometry

Objectives:
•The students will be able to record and measure volume.
•The students will be able to use appropriate units and procedures to calculate volume.
•The students will use one-inch cubes to calculate volume.

Aligned with South Carolina Mathematics Standards: Grade 5
Measurement Strand
•II.E.1
•II.B.1
•I.D.1

Materials:
•One-inch cubes
•Several different size household boxes (rectangular). (examples: cereal boxes, tea bag boxes, saltine cracker boxes)
•Pencil
•Paper
•Worksheet (Questions for students to follow) - See Questions Below.

Before the Lesson:
•Review Vocabulary
oVolume
oCubic Inch

Procedure:
•Pair students up or have them work individually.
•Distribute each pair or individual two different size boxes.
•Have the students use the one-inch cubes to measure volume.
•Students will work through the questions on the worksheet provided.

Extension:
•Have much bigger boxes for students to use to calculate the volume. (Students should understand that in order to calculate volume of a rectangle can be figured by multiplying base x height.

Worksheet: Investigating Volume

1)Fill up one box with the wooden, one-inch cubes.

2)How many one-inch cubes make up the length?

3)How many one-inch cubes make up the width?

4)How many one-inch cubes make up the height?

5)Count the number of cubes it takes to fill the box.
Write down the total amount of cubes.

6)Write the formula for finding volume.
V = L x W x H (Volume = Length x Width x Height)

7)Measure (in inches) the length, width, and height of the box.

8)Multiply the length by the width by the height.
