I am anticipating that the algebra behind optimization will be the real issue for my students, so I created this scaffolded assignment to get them thinking about using constraints to write equations in terms of one variable. It builds from being very apparent about which formulas to use and how to solve them to being completely open ended- the way they will actually appear in a Calculus questions. Note that this would be appropriate for an Algebra 2 or a Pre-Calculus class as they study optimization from non-calculus perspective as well! Even an advanced Algebra I class would be able to tackle many of these!

I thought about it in 3 phases...

__Phase 1- Working with the Algebra__
In each of these questions, the equations are given. Students need to isolate variables and use substitution to rewrite.

__Phase 2- Basic Modeling__
In each of these questions, a basic scenario is given that can be translated easily into an equation. Constraints are labelled as such. Students need to generate their own equations, then use substitution to rewrite.

__Phase 3- Removing the Scaffolding__
These questions progressively remove the scaffolding, ending in a problem that is worded in the way an optimization problem would be. Students should be able to rely on their experience form the previous questions to solve these.

Feel free to adapt and let me know your thoughts! Happy Optimizing!
