Why do different jobs pay so differently? top-paid teacher earns in a year. On one hand, this seems unfair. On the other hand...it still seems unfair. But there’s a reason some jobs pay so much better than others.

In this lesson, students use unit rates to compare how much different professions make per year/day/hour and discuss ways to possibly equate compensation with social contribution.

REAL WORLD TAKEAWAYS

  • Different professions earn vastly different amounts. More money doesn’t always mean the job is more “valuable.”
  • When the payer/employer benefits directly from the value an employee generates – e.g. having LeBron James on your NBA team means you’ll sell millions more in tickets, swag, etc. – then the employer is likely to pay for that value.

MATH OBJECTIVES

  • Use ratio and rate reasoning to solve real world problems
  • Calculate daily and hourly unit rates
  • However, in other professions that generate value for society at large – e.g. a teacher increases students’ future earnings, the President boosts economic performance – that value is often not reflected in compensation.

Appropriate most times as students are developing conceptual understanding.

Ratios & Unit Rates
Content Standards 6.RP.2 Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger." 6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. (a) Make tables of equivalent ratios relating quantities with whole- number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios. (b) Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed? (c) Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent. (d) Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
Mathematical Practices MP.3 Construct viable arguments and critique the reasoning of others. MP.8 Look for and express regularity in repeated reasoning.
