Instructional Ideas

• Team teach with the Algebra II teacher and chemistry teacher

Classroom Considerations

• Relies on prior knowledge of solving systems of equations using a matrix
• Plan to provide graphing calculators and instructions for solving matrices on them for pupils that don't bring a calculator to class

Pros

• Connects math and science topics
• Teaches a method to balance chemical equations not taught in most science classes

Cons

• None
