An Introduction To Volume
Objectives:
L To count volume in cubic units
L To multiply to find volume
L To estimate volume
L To write a multiplication sentence to find the volume
L To discover volume of different containers
L To make a cost analysis of different brands of popping corn
L To learn the definition of volume
Materials Needed:
L Connecting cubes or base ten blocks
L Rectangular containers similar in size
L Potting soil
L Cubic rulers
L Work sheets
L Three different brands of unpopped popping corn
L Air popcorn popper
L Bowls or bags for popcorn
L Calculators
Recommended Strategy:
Volume Measurement
Students should work in groups of four.
Place several rectangular containers similar in size on the table. Each
container should be numbered. Have one student put the containers in order of
total volume. Ask the class if it is correct. Each group should write down
the order they think the containers should be in. Write each group's answer on
board. Divide containers among groups to measure volume. The group that wins
gets the point or prize.
Each group will have one clear rectangular container. Have the students use
base ten blocks to estimate the volume of their container by making a model of
the container. Each group will then put their model inside the container to
check their estimation. The group which comes the closest to the correct volume
wins the prize.
Using these same clear containers, tell the students they will fill flower pots
with soil. Give each group a rectangular flower pot or box and a ruler. They
are to measure the flower pot/box to get the volume. They must write a number
sentence. Write each number sentence on the board. Each group will then use
soil to fill their flower pot to check measurement. The group which comes the
closest to the correct volume wins. You can give them seeds to plant and
observe the growth.
Performance Assessment:
L Students should use base ten blocks to design their own rectangular prism.
L They will make a drawing of the solid figure with accurately labeled
dimensions.
L They will state volume.
Conclusion:
Students will be able to learn how to estimate volume using the phenomenological
approach as well as participate in a hands on activity to calculate volume.
Once skill is learned, students will be able to apply to real life situations.
