Teach Python functions from start to finish with this complete Unit 7 bundle for Computer Science Principles (CSP).

This bundle combines all Unit 7 instructional lessons and all Unit 7 assessments, giving you everything you need to teach, practice, assess, and grade functions and program organization in one streamlined package.

Students progress from understanding what functions are to writing, using, returning values from, and refactoring functions, then demonstrate mastery through two quizzes and a capstone-style mini project.

Designed in the Mr. H Codes instructional style, this bundle is clear, structured, student-friendly, and sub-ready, making it ideal for daily instruction or long-term planning.
