Quick Questions

Shade in the A or B circle for each question.

1. Which shape do you use for each action step in a flowchart sequence?

A A rectangle

B An oval

2. Which shape do you draw at the very beginning of a sequence?

A A Start rectangle

B A Start oval

3. How many arrows leave each step in a simple sequence?

A One arrow out

B Two arrows out

4. Which label is the best for a step in the flowchart?

A First of all, I think we should probably pour some cereal into the bowl

B Pour cereal into bowl

5. What does an arrow in a flowchart show?

B How big the step is

Match the Pairs

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

Left column		Right column
1(Start) → [Get out bowl] → [Pour cereal] → (End)		AAn arrow shows which step comes next, so you read the steps in the direction of the arrow
2[Pour milk] → [Eat cereal]		B[Pack school bag]
3Each step in a sequence has one arrow in and one arrow out, except Start (no arrow in) and End (no arrow out)		CThe arrow is missing, so we cannot tell the order. Each step needs an arrow joining it to the next step.
4Steps are labelled with short action phrases that start with a doing word		D[Wash hands] → [Dry hands] → [Put on towel]
5[Brush teeth] and [Rinse mouth] have no arrow between them		EPut on socks has two arrows out. A sequence step has only one arrow out.
6[Put on socks] → [Put on shoes] and also [Put on socks] → [Tie laces]		FA flowchart sequence: one line of steps from the Start oval to the End oval

Answer Key

Drawing a sequence in a flowchart

Section A: Quick Questions

A — A rectangle

B — A Start oval

A — One arrow out

B — Pour cereal into bowl

A — Which step comes next

Section B: Match the Pairs

(Start) → [Get out bowl] → [Pour cereal] → (End) → A flowchart sequence: one line of steps from the Start oval to the End oval

[Pour milk] → [Eat cereal] → An arrow shows which step comes next, so you read the steps in the direction of the arrow

Each step in a sequence has one arrow in and one arrow out, except Start (no arrow in) and End (no arrow out) → [Wash hands] → [Dry hands] → [Put on towel]

Steps are labelled with short action phrases that start with a doing word → [Pack school bag]

[Brush teeth] and [Rinse mouth] have no arrow between them → The arrow is missing, so we cannot tell the order. Each step needs an arrow joining it to the next step.

[Put on socks] → [Put on shoes] and also [Put on socks] → [Tie laces] → Put on socks has two arrows out. A sequence step has only one arrow out.

Section C: Definitions

flowchart sequence — A line of rectangles joined by arrows from the Start oval to the End oval, with one arrow in and one arrow out of each step. Each step is a short action phrase.

Section D: Fill in the Blanks

(Start) -> [Get a bowl]
-> [Pour cereal] -> [Add milk] -> (End)

(Start) -> [Get a bowl]
-> [Pour cereal] -> [Add milk]
-> (End)

(Start) -> [Pack bag] -> [Walk to school]
-> (End)

Start and End shape: oval
Step shape: rectangle
Arrows out of each step: 1

Arrows into each step: 1
Arrows out of each step: 1

Section E: Spot the Error

B — The arrow points backwards. Arrows in a sequence must point forward to the next step, so it should be [Get a bowl] -> [Add cereal].

A — Start must be an oval, drawn with round brackets here, not a rectangle. It should be (Start) -> [Pack bag].

D — The last step has no arrow out, so the flowchart never reaches the End oval. It should be [Get dressed] -> (End).

C — This step has two arrows out. In a sequence each step has only one arrow out. It should be [Boil water] -> [Pour water].

B — The label [Name] is just a thing, not an action. Each step needs a short action phrase, such as [Type a name].
