Volume

We are about to study volume. Volume is a measurement of size. It is the amount of space an object takes up.

If the volume is a container, such as a box or a jar, then it is the amount of space inside.

Students will explore ways to find volumes of both solid objects and containers.

Students will estimate the volumes of small objects by making models from centimeter cubes. They will then measure the volume of these objects by displacement, putting them under water in a graduated cylinder and measuring how much the water rises.

Students will measure the volume of containers by pouring graduated cylinders full of water into the containers and using addition and subtraction to find the total volume. They also use their data to solve problems involving multiplication and division.

The metric system measure volume in liters, milliliters, and cubic centimeters (1 milliliter=1 cubic centimeter). In the US common units include the gallon, quart, and cubic inch.

Practice: Help your child find containers that hold cups, pints, quarts, or gallons.
