What do we call it when we put blocks in a special order to make things happen in coding?

• 
  Task

• Program

• Sequence

• Command

Answer explanation

Imagine when you brush your teeth, you follow the steps: 1. Take the toothbrush 2. Put on toothpaste 3. Brush 4. Wash & dry the toothbrush In coding, it's similar. We arrange blocks in a sequence to make cool things happen!

What are two types of sequences?

• Fast & Flexible

• Flexible & Fixed

• 
  Fixed & Iterable

• 
  Fixed & Fast

Answer explanation

Some sequences have only one correct order, like washing hands (wet, soap, rinse). That's fixed. But in flexible sequences, there are many ways to do something, like taking different roads to reach your favorite park!

What term is used to describe a special set of instructions for solving a problem in the right order?

• 
  Events

• Iteration

• Conditionals

• Algorithm

Answer explanation

Just like when we brush our teeth, doing it in the right order is important. Computers need special instructions in the right order too, like a set of magic steps called an algorithm!

Suppose there are different ways to arrange code blocks and solve a puzzle on code.org. What is that type of sequence?

• Flexible Sequence

• Fixed Sequence

• 
  Both A and B

• None of these

Answer explanation

Imagine you can build a puzzle with blocks in different ways. In coding, when we can solve puzzles in different ways by arranging code blocks, it's called a Flexible Sequence!

Let's put the steps in the right order for filling a glass with water:
(a) Turn on the tap.
(b) Grab your favorite glass.
(c) Turn off the tap.
(d) Place the glass under the running water.

• a, b, c, d

• c, a, d, b

• 
  b, a, c, d

• b, a, d, c

Answer explanation

First, take your favorite glass. Then, place it under tap. After that, turn on the tap. And when your glass is full, turn off the tap. If you change the order, you might end up with an empty glass! Just like following a story, in coding, we need to put the instructions in the right order for the computer to do the right things!

Which of the following is a method to repeat a set of instructions in programming?

• Loop

• Sequence

• Function

• Variable

In programming, what do we call a condition that must be met for a certain action to occur?

• Loop

• Function

• Conditional

• Sequence
