Information Technology: Photoshop Scale
Lesson Plans


Photoshop Scale is a sample Information Technology lesson created by a CTE and math teacher team from Iowa. The lesson’s objective is to help students resize an image into given parameters without distorting the image. The CTE concept taught in this lesson is image resizing. Math concepts include ratio, proportion, scale, and equivalent fractions.

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. Math-in-CTE’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.
