Strategies: Additional Instruction and Practice
The following activities are suggestions for working with students who need additional instruction and practice. We hope that the activities spark ideas and conversations among teachers about useful classroom strategies that can supplement existing curriculum.

Activity 1

Help students determine which surface area or volume formula
to use to solve a particular problem. Provide students with a list of problems
that require different formulas. Ask students to decide which formula they
should use for each problem. Later they can use the formulas to calculate
the answers.

Activity 2

To help students understand surface area and volume, have
students create a package for golf balls. Students can create prisms, cylinders,
or pyramids. They should determine how much material they will need to create
the package and how much room is inside. Challenge students by asking them
to find the cost of their package given a specified cost per square centimeter
for the material.
