options: Counting & Cardinality: students learn to know number names and the count sequence, count to tell the number of objects, and compare numbers.

Ratios & Proportional Relationships: students learn to recognize, describe, represent, and reason with ratios, rates, proportional relationships, and percent.

Modeling: students learn to choose and use appropriate mathematics and statistics to analyze real-world empirical situations, improve decisions, and report on their conclusions and the reasoning behind them.

Geometry: students learn to classify geometric figures by their properties, and understand and compare the relationships between them. Students develop and use formulas to compute lengths, areas, and volumes, and they use transformations to generate new shapes and compare existing ones. Geometry can be studied with and without coordinates.

Number Systems and Quantity: students learn to understand the complex number system and reason quantitatively.

Number & Operations - Fractions: students learn to understand fractions as numbers and may work with them using addition, subtraction, multiplication, and division.

Measurement & Data: students learn to work with data and measure attributes such as time, money, length, area, and volume. They may learn to compare measurements to operations and convert between different units of measure.

Number & Operations in Base Ten: students learn to work with the base-ten system and build place value understanding.

Statistics & Probability: students learn to analyze and produce data distributions, and build understanding of univariate and bivariate data. They learn to interpret data, make statistical inferences, justify conclusions, understand rules of probability, and use probability to make decisions.

Functions: students learn to define, use, and evaluate functions to model relationships between quantities.

Operations & Algebra: students learn to solve problems using algebraic thinking and operations such as addition, subtraction, multiplication, and division. They may learn to identify and explain arithmetic patterns, evaluate or manipulate numerical expressions, and reason with equations and inequalities.

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?

Here is some information about the employees:
