1. How can I represent all possible solutions to a situation that is limited in different ways by various resources or constraints?

2. M1 5.1
Pet Sitters
Objectives:
Represent constraints by equations or inequalities, and by systems of equations and/or
inequalities, and interpret solutions as viable or non-viable options in a modeling context.

3. Hold WB

5. Distribute Handout 1.
Students should complete #1-7 in seat pairs.
Discuss
Distribute WB
Read after bullets individually and make recommendations – no partners
Discuss using next slide

6. Discuss Watch for students who focus on the following ideas:
*Students who calculate the intercepts of the constraints
*Students who make note of an “exchange rate” between cats and dogs in terms of either of the constraints.
*Students who create charts to keep track of the combinations of dogs and cats they have tried
*Students who plot combinations on a coordinate grid to keep track of the combinations they have tested.
*Students who try to write equations or inequalities to represent the constraints.

9. Exit ticket for students:
Explain how you represented the two constraints given in this problem situation and what your representation revealed.
