Apply

Review your past projects for opportunities to use functions with parameters.

Reflection

• How do parameters allow for more flexible code?
• Review the functions you have learned, like splash and say, and identify which ones have parameters.
• Where might parameters be used in your previous projects?

Homework

• Complete the problem set at Problem Set: Parameters.
• You may use block or text-based programming for the problem sets.
• Comment your code as your work.
