Bell Work

Bell Work. Consider a career in which a person could expect to make a salary of $38,500 per year after only two years on the job. Is that person earning more or less than a welder who makes $21.00 per hour? Take 3 – 5 minutes to work out your answer.

  1. Bell Work • Consider a career in which a person could expect to make a salary of $38,500 per year after only two years on the job. • Is that person earning more or less than a welder who makes $21.00 per hour? • Take 3 – 5 minutes to work out your answer. • Compare/Share your solution with a partner. • Hone your answer so that you can explain it clearly to someone else. See note

  2. Earning a salary vs. working by the hour Is one better than the other?

  3. Objective • Topic: Annual salary compared to Hourly pay • Do: Calculate an equivalent earning potential • Level: Applying See note

  4. College and Career Ready Math • Standard: HS.N-Q.1 Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. See note

  5. Using unit rates • Let’s look at the problem mathematically: See note

  6. Same problem… • Maybe you started with the welder’s pay and found an equivalent annual salary. Here’s how you might set up the problem: See note

  7. Compare • $95,700 annual salary $46 per hour • What hourly rate would be comparable to this salary? • Consider a few things: • “Full time” is usually 40 hours per week. • Sick leave and vacation time is already included. • Over time is also included. • Who makes this kind of money? What do they do for a living? How much education/training do they need? See note

  8. Minimum + • You worked for minimum wage ($7.90 per hour) all summer. Then you received a 10% ($0.79) raise. • If you work 25 hours every week while you are taking classes at the community college, how much do you earn in 2 years? • Additional information: you took an equivalent of 5 weeks sick leave and vacation time during the two years. See note

  9. Hard work pays… • Is there any way a person who works at a rate of $32.50 per hour could possibly make more than someone who makes a salary of $68,000 per year? • Justify your answer mathematically and realistically. See note

  10. Closure Write your name on a sticky note, and decide where you will place it on the Traffic Signal poster as you go. • Green Light Means that you are “good to go” with the idea of finding equivalent hourly and annual pay rates. • Yellow Light Means that you are proceeding with caution because you are beginning to understand, but are not quite sure you can do this kind of problem by yourself. • Red Light Means that you need to stop right here until you get more instruction and help because you really don’t understand today’s lesson.

  11. Standards for Math Practice • HS.MP.1 Make sense of problems and persevere in solving them. • HS.MP.3 Construct viable arguments and critique the reasoning of others. • HS.MP.4 Model with mathematics.
