Name

1. How many times has this pattern been repeated (including the pattern in brackets)?

• 2
• 3
• 4
• 5
• 6

2. How many times has this pattern been repeated?

• 2
• 3
• 4
• 5
• 6

3. In the box below, write the output for this algorithm:

4. Following a ‘pen down’ command (PD), which of these commands would draw the longest line?

• FD 10
• LT 90
• FD 50
• LT 20

5. Which of these is an example of a count-controlled loop? (Only one answer is correct.)

• FD 100 RT 90 FD 100 RT 90
• REPEAT 2 [FD 100 RT 90]
• FD 100 FD 100 FD 100 FD 100

6. Following a ‘pen down’ command (PD), which of these code snippets would draw a square?

• REPEAT 3 [FD 100 RT 120]
• REPEAT 4 [FD 100 RT 90]
• REPEAT 4 [FD 90 RT 100]
• REPEAT 4 [FD 100 RT 45]

7. Why doesn’t this code for a triangle work? (Only one answer is correct.)

• A command is spelt incorrectly
• A space is missing
• There should be a 4 after REPEAT
• The value after FD is incorrect

8. Which picture represents the output for this code:

• 
• 
• 
• 

9. Match the code below to the algorithm for an octagon:

• A. REPEAT 8 [FD 45 LT 90]
• B. REPEAT 45 [FD 8 RT 50]
• C. REPEAT 8 [FD 50 RT 45]
• D. [REPEAT 8 FD 50 RT 45]
