### Collection Funded by:

Level 6 of the WorkKeys Applied Mathematics assessment requires learners to solve complicated problems. These videos and worksheets, which originally appeared in KET’s Workplace Essential Skills and GED Connection series and accompanying workbooks, are designed to help learners apply mathematical reasoning, critical thinking, and problem-solving techniques to work-related problems.

Students studying for the GED® credential may also find practicing applied mathematics helpful. The GED® test requires test-takers to employ a wealth of mathematical skills, including those covered here.

These resources are part of KET’s Applied Mathematics: Resources for WorkKeys® and GED® Preparation collection.

Background Essay

Applied Mathematics

Math skills are crucial in almost any work environment. Register receipts, spreadsheets, budgets, and the company’s bottom line are just a few of the aspects of work in which employees are required to use some math knowledge. Therefore, one set of skills required by the WorkKeys assessment is applied mathematics. WorkKeys learners must be able to apply mathematical reasoning, critical thinking, and problem-solving techniques to work-related problems.

Each level of the WorkKeys Applied Mathematics assessment incorporates the skills from the previous levels. Level 6 of the assessment includes math problems that require considerable translation from verbal form to mathematical expression. Problems at this level also require considerable setup and involve multiple-step calculations.

Learners are required to use fractions, negative numbers, ratios, percentages, or mixed numbers; use formulas to change from one unit to another; find areas of basic shapes when it may be necessary to rearrange the formula, convert units of measurement in the calculations, or use the result in further calculations; find the volume of rectangular solids; and perform other mathematical operations.

Students studying for the GED® credential may also find practicing applied mathematics helpful. The GED® test requires test-takers to employ a wealth of mathematical skills, including those covered here.

“Signed Numbers” and “A=LW” originally appeared in “Introduction to Algebra,” a program in KET’s GED Connection series.

This Teachers’ Domain resource was created as a result of a correlation of KET’s adult education materials to the WorkKeys® Assessments for the National Career Readiness Certificate™.

Discussion Questions

• One educator in the “Signed Numbers” video segment talks about treating positive and negative numbers as directions. Discuss this concept.
• Discuss the rules for working with positive and negative numbers, and create a list of all of the rules mentioned in the “Signed Numbers” video segment.
• The video segment “A=LW” uses the formula for the area of a rectangle as an example. Discuss other common formulas for finding area or volume. Try using inverse operations with these formulas.

• Teaching Tips

This Teachers’ Domain resource includes two videos and worksheets designed to demonstrate WorkKeys skills. Below are suggestions for using these elements in a classroom setting and more ideas for teaching applied mathematics.

• After discussing the concept of looking at positive and negative numbers as directions, practice by picking out some destinations and calculating distances on a map.
• Practice working with signed numbers by creating a sample workplace budget.
• Find areas and volumes for rooms and objects around your building, and practice inverse operations.
• In a workplace environment, employees may be required to combine their math skills with basic computer skills. Incorporate technology into your applied mathematics lessons by including Microsoft Excel, Google Docs spreadsheets, or other software programs that work with formulas and equations.
