Instructional Ideas

• Use the hand-on activity when graphing linear functions
• Pair with science and math teachers to teach the concept together

Classroom Considerations

• Requires materials to create the circuit
• Learners should have knowledge of linear functions

Pros

• Used with a variety of levels based upon focus
• Provides an application of linear functions

Cons

• The materials needed can be expensive
• Use of the breadboard may be difficult for some
