Quick Questions

Shade in the A or B circle for each question.

1. Which shape marks the Start and Stop of a flowchart?

A Process (rectangle)

B Terminator (rounded oval)

2. How many Start terminators should a flowchart have?

A One

B One for every decision

3. Which statement about arrows and Start is correct?

A No arrow goes into Start

B An arrow can loop back into Start

4. Where does every path in a flowchart finish?

A At a process box

B At a Stop terminator

5. Which is the correct way to label the first and last shapes?

A Start and Stop in rounded shapes

B Start and Stop in diamonds

Match the Pairs

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

Left column		Right column
1Oval labelled Start		AAn arrow must never go into Start. A loop should return to a step after Start, such as a decision or process.
2Oval labelled Stop		BBoth the Yes and No branches of a decision lead to Stop
3A flowchart has exactly one Start, and the Start has no arrow going into it		CMarks where a path of the flowchart ends; no arrow leaves it
4Every path in the flowchart must finish at a Stop terminator		DStart (oval) with one arrow leaving it
5A loop arrow goes back up into the Start oval		EMarks where the flowchart begins; there is only one of these
6The No branch of a decision ends with an arrow that points to nothing		FThe path has no Stop terminator. Every path must end at a Stop oval.

Answer Key

Terminator symbol

Section A: Quick Questions

B — Terminator (rounded oval)

A — One

A — No arrow goes into Start

B — At a Stop terminator

A — Start and Stop in rounded shapes

Section B: Match the Pairs

Oval labelled Start → Marks where the flowchart begins; there is only one of these

Oval labelled Stop → Marks where a path of the flowchart ends; no arrow leaves it

A flowchart has exactly one Start, and the Start has no arrow going into it → Start (oval) with one arrow leaving it

Every path in the flowchart must finish at a Stop terminator → Both the Yes and No branches of a decision lead to Stop

A loop arrow goes back up into the Start oval → An arrow must never go into Start. A loop should return to a step after Start, such as a decision or process.

The No branch of a decision ends with an arrow that points to nothing → The path has no Stop terminator. Every path must end at a Stop oval.

Section C: Definitions

Terminator — A rounded (oval) flowchart shape that marks the Start and the Stop of a flowchart. There is one Start, every path ends at a Stop, and no arrow goes into Start.

Section D: Fill in the Blanks

(Start)
[INPUT Age]
(Stop)

(Start)
[OUTPUT "Welcome"]
(Stop)

<Mark >= 50?>
Yes: [OUTPUT "Pass"] -> (Stop)
No: [OUTPUT "Fail"] -> (Stop)

Start terminators allowed: 1

Start: arrows in = 0, arrows out = 1

Section E: Spot the Error

B — A flowchart has only one Start terminator. The second oval labelled Start is wrong. Line 2 should be the Input parallelogram, Para: INPUT A.

C — Stop is a terminator, so it must be a rounded oval. A rectangle is the process symbol. It should be Oval: Stop.

C — No flow line may go into Start. The flowchart begins at Start and the arrow must carry on to Stop, so it should be Arrow: INPUT -> Stop.

B — Stop marks the end of a path, so it cannot come straight after Start. The steps would never run. Line 2 should be the Input shape, Para: INPUT Price.

D — Every path must end at a Stop terminator. The Yes branch leads nowhere. It should be Yes: OUTPUT Adult -> Stop.
