Block Programming Problem Solving

📚 Part 1: Multiple Choice (Branching, Iteration, Variables, Functions)

1. Which block is used to make a decision when something is true?

If / If-Else block

Repeat block

Variable block

Define function block

2. Which loop is best when you do not know how many times you must repeat until a condition happens?

Repeat n times

Forever

Repeat until (condition)

When flag clicked

3. Check all that apply: Which tasks are good uses for a variable?

Store a player's score

Keep a countdown timer

Draw a sprite on the stage (visual only)

Hold a choice that changes between scenes

4. What is the main advantage of making a custom function (defined block)?

Reuse code and make programs easier to edit

Make the program run slower

Change a variable's data type automatically

Increase the colour depth of sprites

✏️ Part 2: Short Answers & Editing Programs

5. Write a simple block-style if statement in words or short pseudocode: If the variable distance is less than 10, say "Too close".

6. A sprite should move 10 steps but the program uses repeat 5 with move 2 steps. Explain the bug and how you would edit the blocks to fix it.

7. Describe how you would use a variable to count the number of times a button is pressed. Include the variable name and where you change it.

8. Explain in one sentence why testing and editing your blocks is important when solving problems.

🎨 Part 3: Design & Debug (Apply Functions and Parameters)

9. Design a function called moveToGoal(speed, steps). In the box, write short block-style pseudocode that shows: set speed, repeat moving by speed until steps are completed, then say "Arrived".

10. Draw a simple flow showing the decision and loop for the function above: start → check steps remaining → move → update steps → repeat or finish.
