Block-Based programming language

Which operator block would you use to check if a score is greater than 50 in Scratch?

• Use the 'equal to' (=) operator block.
• Use the 'greater than' (>) operator block.
• Use the 'not equal to' (≠) operator block.
• Use the 'less than' (<) operator block.

You want your sprite to say “You win!” if the score equals 100. Which operator block should you use?

• score > 100

• score < 100

• score = 100

• score ≠ 100

Which operator block would you use if you want something to happen only when the player’s score is more than 10 and they have lives left?

• or

• not

• and

• join

Look at this condition: if score > 10 or score < 0. What might be a problem with using this in a game?

• It doesn’t use a variable.

• It always makes the sprite say “Game Over.”

• It’s impossible for score to ever be greater than 10 or less than 0.

• The condition might be true even if the score is not in the danger zone.

What does the not operator block do in Scratch?

• It adds two numbers together.

• It checks if two things are equal.

• It makes a condition false if it was true.

• It repeats an action forever.

You want your game to end if the player has no lives OR time is up. Which operator block helps you do this?

• 
• 
• 
• 

You want your sprite to say “Hello, [name]!” using the name a user types. Which Operators block helps you do this?

• 
• 
• 
• 

Which operator would you most likely use if you want something to happen after 30 seconds?

• join

• length of

• timer > 30

• pick random

You made a Scratch project where the sprite is supposed to say "Hello!" when you click the green flag, but nothing happens. What is the best first step to debug (fix) the problem?

• Delete the sprite and start over.

• Click the red stop sign many times.

• Check if you used the “when green flag clicked” block correctly.

• Add more costumes to the sprite.

Your sprite keeps spinning forever and won’t stop. What is the most likely cause?

• You used the wrong costume.

• You used a “forever” loop without a stopping condition.

• The sprite is broken.

• You clicked the wrong flag.
