Type: Lesson/Unit Plan

Overview:

This lesson covers functions as a way to organize code, make it more readable, and remove repeated blocks of code. The class learns that higher level or more abstract steps make it easier to understand and reason about steps, then begins to create functions in Game Lab. At the end of the lesson, the class uses these skills to organize and add functionality to the final version of their side scroller game.

2) Define a process as a function.

Example: Functions or sets of steps combined to produce a process: turning off your alarm + getting out of bed + brushing your teeth + getting dressed = morning routine.

Unpacked Content
Evidence Of Student Attainment:
Students will:
  • list a set of steps taken to complete a process and name that process as a function.
Teacher Vocabulary:
  • process
  • function
Knowledge:
Students know:
  • that often people seek to simplify processes; rather than listing all of the steps needed to take a shower, one simply uses the function "shower".
Skills:
Students are able to:
  • combine or join steps such as algorithms to create a function.
Understanding:
Students understand that:
    it is simpler and less confusing to identify processes rather than steps.

5) Identify algorithms that make use of sequencing, selection or iteration.

Examples: Sequencing is doing steps in order (put on socks, put on shoes, tie laces); selection uses a Boolean condition to determine which of two parts of an algorithm are used (hair is dirty? True, wash hair; false, do not); iteration is the repetition of part of an algorithm until a condition is met (if you're happy and you know it clap your hands, when you're no longer happy you stop clapping).

1) Create a function to simplify a task.

Example: Get a writing utensil, get paper, jot notes can collectively be named "note taking".

Unpacked Content
Evidence Of Student Attainment:
Students will:
  • summarize a collection of steps or algorithms as one function.
Knowledge:
Students know:
  • an algorithm is the set of commands to complete a task.
Skills:
Students are able to:
  • combine several algorithms or tasks as a named function.
Understanding:
Students understand that:
  • it is more efficient to label an activity or program as a function than to list all of the individual steps or algorithms that make up the function or activity.
