EOU Assessment: 1.3 Sub-routines

Section A: Fill in the Blanks

Instructions: Complete each sentence using the correct word from the word bank below. Each word is used once.

1. A is a separate section of code from the main program designed to perform a specific, reusable task.

2. To a sub-routine means to give it a name and write all the instructions inside it.

3. In Scratch, sending out a signal or message to all other sprites and scripts is called a .

4. When two sprites in a program affect or depend on each other's actions, we say they .

5. The process of setting up everything ready before a game starts (such as setting the score to 0 or moving a sprite to a start position) is known as .

6. A is used in programming to store data that can change during the program.

Section B: Multiple Choice Questions

Instructions: Select the single best answer for each question.

1. Why do programmers use sub-routines in their code?

A) To make the program run slower.

B) To increase the overall length of the code lines.

C) To make code easier to understand and reduce repetition.

D) To prevent variables from storing data.

2. In a classroom gymnastics simulation, students repeat a "Handstand" move 4 times. What is the most efficient way to write this in an algorithm?

A) Write out the 4 detailed handstand steps 4 separate times.

B) Define a "Handstand" sub-routine once and call it 4 times.

C) Delete the handstand steps from the main routine.

D) Create 4 separate sprites for each handstand move.

3. Which Scratch block asks the user for input and stores the typed response?

A) broadcast [message]

B) ask [question] and wait

C) change [Score] by 1

D) switch backdrop to [Party]

4. In a computer game, player 1 gains points while player 2 loses remaining attempts. Which pair of variables would best track this?

A) Score and Lives

B) Answer and Sprite

C) Broadcast and Receive

D) Voice and Language

5. What does the Scratch 'Text to Speech' extension allow a project to do?

A) Record the student's voice through the microphone.

B) Speak sentences out loud, change voice sounds, and alter speech languages.

C) Automatically correct spelling mistakes in typed text boxes.

D) Translate spoken words into written code blocks.

6. A student wants to change the wrong-answer sound effect in a 10-question quiz game. Why is using a sub-routine for incorrect answers helpful here?

A) They only need to change the sound block once inside the sub-routine rather than 10 times.

B) It automatically changes the player's score to a negative number.

C) It stops the game from needing any variables.

D) It deletes all wrong responses from the program memory.

Section C: One-Word Answers

Instructions: Write the correct single-word answer for each item.

1. What command word is used to trigger a defined sub-routine to run its instructions?

2. Which standard variable in Scratch automatically stores the text typed into an ask block?

3. What type of extension in Scratch adds blocks that convert text into spoken sound?

4. Besides broadcast, what Scratch feature under "My Blocks" lets programmers define custom reusable blocks?
