Parameters & Generalization

Summary

This chapter teaches students to add parameters, including number, text, and Boolean parameters, to a custom block so that a single procedure can generalize across many situations rather than being rewritten for each one. Students learn about default values, argument values, and how to combine multiple parameters in one block. It builds on the variables work from Chapter 7, the conditional logic from Chapter 8, and the custom block skills from Chapter 9. After completing this chapter, students will be able to design parameterized custom blocks that adapt their behavior based on the values passed in.
