Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1REPEAT 5 TIMES		AEND REPEAT is missing, so there is no sign of where the loop stops. Add END REPEAT after Stamp.

Answer Key

REPEAT a set number of times

Section A: Quick Questions

A — REPEAT 3 TIMES clap END REPEAT

B — 4 times

B — END REPEAT

A — 4

A — REPEAT 2 TIMES step forward turn left END REPEAT

Section B: Match the Pairs

REPEAT 5 TIMES → Runs the indented steps under it exactly 5 times, then moves on to the next step

END REPEAT → Marks the place where the loop stops and shows the steps inside are finished

To clap 3 times, put the number 3 in the loop and indent the clap step → REPEAT 3 TIMES Clap END REPEAT

A step written after END REPEAT runs only once, after the loop has finished → REPEAT 2 TIMES Jump END REPEAT Sit down

REPEAT 4 TIMES Step forward END REPEAT → The step inside the loop is not indented, so it is not clear which step gets repeated. Indent Step forward under REPEAT 4 TIMES.

REPEAT 6 TIMES Stamp Sit down → END REPEAT is missing, so there is no sign of where the loop stops. Add END REPEAT after Stamp.

Section C: Definitions

REPEAT n TIMES — Runs the indented steps under it exactly n times, then moves on to the next step. Use END REPEAT to show where the loop stops. Example: REPEAT 5 TIMES.

Section D: Fill in the Blanks

REPEAT 3 TIMES
  Jump
END REPEAT

REPEAT 5 TIMES
  Draw a side and turn
END REPEAT

REPEAT 4 TIMES
  Hop forward
END REPEAT

REPEAT 6 TIMES
  Roll the dice
END REPEAT

REPEAT 3 TIMES
  Knock on the door
END REPEAT

Section E: Spot the Error

D — A counted loop must finish with END REPEAT. END LOOP is not the right keyword. Line 4 should be END REPEAT.

A — The loop needs a number to say how many times to repeat. Line 1 should be REPEAT 5 TIMES.

C — A counted loop must finish with END REPEAT. STOP REPEAT is not the right keyword. Line 3 should be END REPEAT.

A — A counted loop starts with the word REPEAT, not LOOP. Line 1 should be REPEAT 3 TIMES.

C — The body should run just one lap each time. Running 4 laps inside a loop that repeats 4 times would give 16 laps. Line 3 should be ' Run one lap'.
