Lesson Title Finding the Unknown Percent, Part, or Whole for Trade Jobs
Unit Title Construction & Trades
NRS Level Level 4
Length of Lesson 60 minutes
Lesson Purpose

Students need to be able to work with percents as they relate to trade jobs in order to improve their employability skills. Specifically, students will learn to solve word problems that ask for an unknown percent, part, or whole. These calculations are imperative to ensure trade jobs are performed correctly.

Lesson Objectives

At the end of this lesson, students will be able to solve for an unknown percent, part, or whole to solve word problems in the context of trade jobs.

Student Target

“I can solve work related work problems that ask me to find the unknown percent, part, or whole.”

 

 

CCR Focus Standards
Number and Ratios - Level D
  • 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.

Supporting Standards
  • Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.

Standards for Mathematical Practice
  • Make sense of problems and persevere in solving them. (MP.1)

  • Reason abstractly and quantitatively. (MP.2)

  • Model with mathematics. (MP.4)
