Learning objective

In this lesson, students examine how dilating a figure can create a sense of perspective in a piece of art. They create a function to dilate their sprite by a specific scale factor, and test their function with a scale factor less than 1 and a scale factor greater than 1. In the second activity, students are introduced to variables as a way to store and track data in a program. Through a teacher-led activity, they examine how variables can be used to control the scale factor of their dilated sprite over time. To conclude the lesson, they reflect in their artist’s journal on how they can create a sense of perspective within their program.

Standards

🌐 CSTA Standards

2-AP-11: Create clearly named variables that represent different data types and perform operations on their values.
2-AP-13: Decompose problems and subproblems into parts to facilitate the design, implementation, and review of programs
2-AP-14: Create procedures with parameters to organize code and make it easier to reuse.
2-AP-17: Systematically test and refine programs using a range of test cases

🇺🇸 Common Core Standards

CCSS.MATH.CONTENT.8.G.A.4: Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

🇺🇸 National Arts Standards

MA:Cr1.1.8: Generate ideas, goals, and solutions for original media artworks through application of focused creative processes, such as divergent thinking and experimenting.
MA:Cr3.1.8b: Refine and modify media artworks, improving technical quality and intentionally accentuating selected expressive and stylistic elements, to reflect an understanding of purpose, audience, and place.
MA:Pr5.1.8c: Demonstrate adaptability using tools, techniques and content in standard and experimental ways to communicate intent in the production of media artworks.
MA:Re8.1.8: Analyze the intent and meanings of a variety of media artworks, focusing on intentions, forms, and various contexts.

Students will use the same project across multiple lessons.
