Homework
1-2 hours per week. Learners should preview and start brainstorming about the problem before class. Learners may work on an extension to the problem after class.

Class Experience

US Grade 8 - 10
Pre-Assignment:
The problem, involving choosing how much of two products to produce, will be posted in the classroom before the class meeting. Learners should familiarize themselves with the problem before the live session, and brainstorming some strategies is recommended. The expectation is not for learners to have completed the problem before class, but to have some ideas of how to start working on it, and maybe to have started some back-of-envelope scratch work.

During class:
We will use tables and graphs to identify which combinations of the two products are possible to produce. To use graphs, we will need to write inequalities for features of the problem which limit our production capabilities, called constraints.
We will use the given sales prices and production costs to write a profit function, then use this function to calculate the profit possible for different combinations of products. As we look for the maximum possible profit, we will try to find patterns to work efficiently.

Extension:
If learners complete the main problem quickly, this will be at least started during the session; otherwise the problem will be posted for learners to work on asynchronously. Learners will consider and form an opinion as to which of two options for increasing their production capacity would increase their profit more.

Learners will be more successful who are already familiar with evaluating formulas given values of variables, graphing linear inequalities, finding and verifying solutions to systems of linear equations, and the relationship in business between income, expenses, and profit. These concepts will be reviewed and discussed, but if many of them are new, the learner is likely to feel overwhelmed.
Learning Goals
Learners will write and graph constraint inequalities to plot the feasible reason of a linear programming problem with two decision variables.
Learners will write an objective function and evaluate it for multiple possibilities within the feasible region.
Learners may discover isoprofit lines and the importance of corners in solving linear programming problems.

Other Details

Parental Guidance
Explain Everything is a shared whiteboard, similar to Google Jamboard but more flexible. Learners do not need an account and can access the board to write on it through a link. Learners who do not specifically want to write on the board don’t need to access Explain Everything at all – I will share the screen in Zoom and they can watch.
