Finance: Depreciation (Double Declining)

Finance: Depreciation (Double Declining)

Math-enhanced CTE lessons are written only after CTE and math teacher teams work together to develop a curriculum map that identifies the CTE concepts and intersecting math concepts (including the Common Core math standards) that are naturally embedded within the CTE curriculum. Once the map is complete, the CTE and math teacher teams, working in communities of practice, select from within it one or more CTE concepts and related math concepts to develop into CTE lesson plans. The Math-in-CTE model’s seven-element pedagogic framework (PDF) guides this lesson development process. When the lessons are complete, the CTE teachers create scope and sequence plans for integrating the lessons into their courses.

Depreciation (Double Declining) is a sample Finance lesson created by a CTE and math teacher team from Iowa. The lesson’s objective is to teach students to calculate depreciation expense and book value using double declining balance methods and compare the outcome to straight line depreciation. The CTE concepts taught in this lesson are depreciation (double declining) and book value. This lesson uses only full-year depreciation and assumes that students have mastered straight line depreciation. Math concepts include formulas, decimals, percentages, exponential decay, and linear relationships.
