This diagram shows the basic flow that almost all computing devices follow. What do we call the missing middle step?

• Sensing

• Process

• Software

• Control

I want to display a pattern on the LED screen. Which block(s) can I use? (Check all that apply)

• 
• 
• 
• 
• 

In which category can I find the blocks I need to check if a button is pressed?

• Input

• Radio

• Variables

• Advanced

I want to write a program that involves repeating the same code multiple times. In which category shown can I find the block I need to achieve this?

• Input

• Math

• Loops

• Logic

We can use Loops to make sure we don't unnecessarily write the same code over and over. We learned in class that good programmers want to keep their code ______ and ______.

• DRY and CLEAN

• LONG and BASIC

• SHORT and COMPLEX

• FUN and EASY

What is it called when we show multiple images or patterns in a sequence to give the illusion of motion? (Hint: we did this with LED patterns in a previous lesson)

• Magic

• Animation

• Inputting

• Packaging

The 'pause' block stops the program for the specified amount of time in milliseconds (1000 ms = 1 second). How long will the program shown here pause for?

• 3000 seconds

• 0.0003 seconds

• 30 seconds

• 3 seconds

When would we want to use a Function in code?

• When we want to store a number value for later use

• When we want to use the same lines of code in multiple places in our program

• When we want to check if a certain condition is true or false

• When we need to take an input from the user

If we run this program, how many times will "Hello" be printed?

• 4

• None

• Infinity

• Once

Answer explanation

The print block is inside a "repeat 4 times" block, but the whole thing is inside a forever block, so it will repeat 4 times, then repeat 4 times again, then again and again...

What does this program do?

• Prints 100, then 99, 98, 97...and so on until 0

• Prints the number 100 one hundred times

• Prints 1, 2, 3...and so on until 100

• Decreases 'count' by 1, but doesn't print anything
