Use after Unit 4, Lesson 8
Read the situation in the task statement aloud, or ask students to read it to themselves quietly.
Tell students to think about these questions:
“What might be some different ways of giving bonuses?”
“Does anyone have a job and has gotten a raise or a bonus? How are your allowances determined? Do they ever change?”
“What variables should be considered? What information do you need to know about the employees to compute bonuses for each of them?”
Give students a few minutes of quiet think time, then ask them to talk over their ideas with a partner. Finally, ask students to share their ideas with the whole class and record these ideas for all to see.
Ask students if they have any questions about the situation.
If students want to know what type of company it is and what jobs the employees are doing, tell them that they can make up a fake company with specific jobs.
Teacher Instructions
As students are considering the situation, prompt them with the following questions, as necessary:
"What are some variables you should consider?"
"Can you think of mathematically different methods to distribute the money?"
"What information would be helpful to know to compute the bonus for each employee?"
Tell students that they can make up the information they need to compute specific bonuses for 2 different methods and to apply them to the situation. In the proposal, students should compute the specific dollar amount each employee receives as a bonus.
If there is time, encourage students to try generalizing any values they invented to use variables instead.
Student-Facing Statement
A project at a large company was very successful, and the company made more money than expected as a result. Your boss has given you the task of coming up with different methods to distribute bonuses to the 5 employees that directly worked on the project. There is a total of
$
8,000 available to distribute.
The method for distributing the money will be shared with the entire company, so it is important that the employees feel the distribution is fair.
Make a proposal with at least two different methods for your boss to choose from. Describe the advantages and disadvantages of each method. Then give your recommendation and provide an argument in its support.
For each of the methods you propose, which of the five employees is most likely to complain about the method being unfair? How would you justify the method to this employee?
Teacher Instructions
As students are considering the situation, prompt them with the following questions, as necessary:
“Which of these variables should you consider?”
“Can you think of mathematically different methods to distribute the money?”
“What additional information would be helpful to know to compute the bonus for each employee?”
Tell students that they can make up any additional information they need to compute specific bonuses for 2 different methods and to apply them to the situation. In the proposal, students should compute the specific dollar amount each employee receives as a bonus.
If there is time, encourage students to try generalizing any values they invented to use variables instead.
