Code.org Lesson 4 - Functions

In a Code.org sequence puzzle, you're tasked with guiding a character to collect all the gems on the screen. Which block is typically used to make the character move multiple steps in a specific direction?

1. "If" Block
2. "Turn Right" Block
3. "Repeat Until" Block
4. "Sound" Block

In a Code.org sequence puzzle, which block is used to create a condition that, when met, allows the program to execute a specific set of actions?

1. "Forever" Block
2. "Move Forward" Block
3. "Repeat Until" Block
4. "If" Block

In a Code.org sequence puzzle, which block is used to create a loop that repeats a specific set of actions a fixed number of times?

1. "Repeat Until" Block
2. "If" Block
3. "Turn Right" Block
4. "Repeat" Block

In programming, what is the primary purpose of using a nested loop structure?

1. To execute a loop only once
2. To create a loop inside another loop
3. o eliminate the need for loops
4. To perform mathematical calculations

KO - Students will understand the concept of functions in programming and apply their knowledge to solve puzzles on Code.org.

All - Students will identify the purpose of functions in coding.

Most - Students will design and implement a custom function with parameters.

Some - Students will create and utilize functions that call other functions (nested functions).

What is a Function?

Think of a function as a mini-program inside your main program. It's like a magical box that does a specific job for you.

Why Do We Use Functions?

Easy Breakdown: Functions help break big problems into small, manageable pieces. Imagine you have a big puzzle; functions are like individual puzzle pieces.

Reuse: Once you make a function, you can use it many times. It's like having a magic spell you can use in different parts of your game or puzzle.

No Need to Know Everything: You don't need to know how the magic inside the box works. You only need to know what goes in (like ingredients) and what comes out (like a cake).
