Foundations of Computational Thinking and Logic

A comprehensive 5-lesson sequence for 10th-grade students exploring the four pillars of computational thinking: decomposition, pattern recognition, abstraction, and algorithmic design. Students progress from conceptual logic to structured pseudocode and logic verification.

Decomposition and Problem Breakdown

Students learn to break down complex problems into atomic sub-tasks and analyze task dependencies using the classic 'PB&J Robot' hook and a project management scenario.

Pattern Recognition in Data

Students examine various datasets and scenarios to identify repeating trends and similarities. They learn how recognizing these patterns allows for the creation of loops and reusable functions in logic design.

Abstraction and Modeling

This lesson focuses on filtering out unnecessary details to create a model of a problem. Students practice abstraction by designing a transit map that ignores geographical accuracy in favor of topological clarity.

Developing Pseudocode and Flowcharts

Students synthesize the previous concepts to write pseudocode for a specific logic puzzle. They utilize standard flowcharting symbols to visualize the flow of control, including decision diamonds and process rectangles.

Algorithmic Logic and Edge Cases

In this final lesson, students trade pseudocode with peers to 'run' the algorithms manually, specifically looking for edge cases where the logic fails. They refine their algorithms to handle unexpected inputs.
