Business Inventory Loss
Traditional math concepts using a CTE example help students learn in context – and visa versa. This lesson uses the scenario of setting up a store and focuses on inventory to learn about using percent. Students work through math examples embedded in the CTE lesson and are able to calculate the percentages that correspond to the different loss categories.

Expected Student Outcomes/Objectives
The students should be able to calculate the percent loss by category (employee theft, shoplifting, back door fraud, and other) for any stores and display the data in a pie chart. Students should also be able to visually identify in order of largest to smallest, the percent loss by category for each store, based on the pie chart data displays.
Description of Activities
1. Introduce the CTE lesson: You are planning on setting up a store, and are thinking about all of the costs associated with this venture. Give me examples. What is meant by the term inventory loss?
2. Assess students’ math awareness as it relates to the CTE lesson.
3. Work through the math example embedded in the CTE lesson.
We want to be able to calculate the percentages that correspond to the different Loss Categories. So let’s do a brief review of how to find percentages. Who can define percent? We need to know how to calculate percentages. There is a proportion that is easy to use when calculating percent.
STEP 1: Use the percent from each category to find the number of degrees that will represent on the circle.
STEP 2: Using a protractor, measure and draw each angle from the center point of the circle.
4. Work through related, contextual math-in-CTE examples.
