Determine whether the point is just right. The interactive allows participants to input a constraint equation. Pupils pick a point and determine whether it is too big, not too big, or just right for the constraint. Using the graphing function, learners plot the point with the appropriate designation.

Instructional Ideas

• Provide the constraint equations
• Lead a discussion on what it means to be too big or not too big in relationship to a constraint

Classroom Considerations

• Pupils should understand that the graph is the representation of the solutions to the equation

Pros

• Uses colors to distinguish between the types of points for clarity
• Allows students to change answers 

Cons

• Does not contain clear instructions about the use of the Pet Sitter resource to get constraints
