Will someone please constrain those pets? Pupils create two constraint equations on the number of cats and dogs for a pet sitter. They choose specific points and determine whether the point satisfies one or both constraints. The interactive plots the points and color codes them based on whether the answer is correct.

Instructional Ideas

• Provide a set of constraints for the class members to use

Classroom Considerations

• Students should understand constraints
• The constraints are equations as opposed to inequalities

Pros

• Uses colors to highlight equations
• Completes the equation of the lines if successful

Cons

• Does not include instructions on the constraints to use
