Quick Questions

Shade in the A or B circle for each question.

1. Your algorithm has the step: 3. IF it is raining THEN take an umbrella. Which flowchart shape do you draw for the IF?

A A plain rectangle

B A diamond

2. Your algorithm has the step: 2. Add 1 to score. Which shape do you draw?

A A diamond

B A rectangle (a step box)

3. Your algorithm says: 4. REPEAT from step 2. How do you show this in a flowchart?

A Draw an arrow going back to the shape for step 2

B Draw a new box that says REPEAT and stop

4. How many flowchart shapes does each numbered step usually become?

A One shape for each step

B One shape for the whole algorithm

5. A flowchart has a diamond that asks: Is score = 10? How many arrows should leave the diamond?

A Two arrows, labelled Yes and No

B One arrow only

Match the Pairs

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

Left column		Right column
13. IF score > 10 THEN say "Win"		ADraw a diamond shape asking "Is score > 10?" with a Yes arrow to a "Win" step
24. REPEAT from step 2		B2. ADD 1 to count → [ ADD 1 to count ]
3Each ordinary numbered step becomes one rectangle shape, joined to the next shape by an arrow		CIF it is raining THEN → <Is it raining?> Yes / No
4A decision in the steps becomes a diamond with two arrows out, labelled Yes and No		DA REPEAT should be an arrow going back to the shape for step 2, not forward to End.
5Step 3: IF age >= 10 → drawn as a rectangle		EDraw an arrow from this step back up to the shape for step 2
6Step 5: REPEAT from step 2 → drawn as a new shape that goes forward to End		FAn IF must be drawn as a diamond, not a rectangle. A rectangle can't show a Yes and No choice.

Fill in the Blanks

Complete each line of code by filling in the missing parts.

IF age >= 10 THEN = _______ shape

REPEAT = arrow ____ to an earlier shape

1. SET total TO 0 Shape for step 1: _________

2. IF count > 5 THEN Diamond question: _____ > 5 ?

Both versions must give the ____ result

Spot the Error

Shade in the letter of the line that contains an error.

Question 1

A Oval: START

B Box: set count to 0

C Box: count < 3?

D Box: add 1 to count

E Arrow: back to the diamond

Question 2

A Diamond: START

B Box: ask for the age

C Diamond: age >= 10?

D Box: say Big kid

Question 3

A Oval: START

B Diamond: add 1 to count

C Diamond: count = 3?

D No: arrow back to the box

Question 4

A Box: lose 1 life

B Diamond: lives = 0?

C No: arrow on to the END oval

D Yes: go to END

Question 5

A 1 START -> oval

B 2 SET n TO 0 -> box

C 3 IF n < 5 -> diamond

D 4 REPEAT -> arrow forward

Answer Key

Turning numbered steps into a flowchart

Section A: Quick Questions

B — A diamond

B — A rectangle (a step box)

A — Draw an arrow going back to the shape for step 2

A — One shape for each step

A — Two arrows, labelled Yes and No

Section B: Match the Pairs

3. IF score > 10 THEN say "Win" → Draw a diamond shape asking "Is score > 10?" with a Yes arrow to a "Win" step

4. REPEAT from step 2 → Draw an arrow from this step back up to the shape for step 2

Each ordinary numbered step becomes one rectangle shape, joined to the next shape by an arrow → 2. ADD 1 to count → [ ADD 1 to count ]

A decision in the steps becomes a diamond with two arrows out, labelled Yes and No → IF it is raining THEN → <Is it raining?> Yes / No

Step 3: IF age >= 10 → drawn as a rectangle → An IF must be drawn as a diamond, not a rectangle. A rectangle can't show a Yes and No choice.

Step 5: REPEAT from step 2 → drawn as a new shape that goes forward to End → A REPEAT should be an arrow going back to the shape for step 2, not forward to End.

Section C: Definitions

step = shape — Each numbered step becomes one flowchart shape. An IF becomes a diamond, and a REPEAT becomes an arrow going back to an earlier shape. Both versions should do the same thing.

Section D: Fill in the Blanks

IF age >= 10 THEN = diamond shape

REPEAT = arrow back to an earlier shape

1. SET total TO 0
Shape for step 1: rectangle

2. IF count > 5 THEN
Diamond question: count > 5 ?

Both versions must give the same result

Section E: Spot the Error

C — A question that makes a choice or decides when to stop a loop must be a diamond, not a box. The line should be 'Diamond: count < 3?'.

A — START is drawn as an oval (rounded shape). A diamond is only for decisions. The line should be 'Oval: START'.

B — Adding 1 is an ordinary step, so it gets a box. Only questions get a diamond. The line should be 'Box: add 1 to count'.

C — A REPEAT is shown by an arrow that goes back to an earlier shape. The No arrow must go back to 'lose 1 life', not forward to END.

D — A REPEAT becomes an arrow going back to an earlier shape so the steps can run again. It should be 'arrow back'.
