This document introduces Flowol programming to Key Stage 3 students and describes how to create a flowchart and program to control a zebra crossing. It explains the different symbols used in Flowol like start/stop, process, input/output, decision, and provides examples. Students are guided to create a flowchart for making a cup of tea with partner using the symbols. Finally, they are instructed to use the worksheet to create a flowchart to control lights at a zebra crossing.

1. Introducing Flowol programming to Key Stage 3

2.  Learn how to create a flowchart.
 Learn how to create a program in Flowol to
control a Zebra crossing.

3.  The Start / Stop symbol shows where a
particular section of a flowchart begins and
ends.
 Every section of your flowchart must include
both a start and a stop symbol.

4.  A process is when an action is performed.
 E.g. Walk to school.

5.  An input or output shows something entering
or exiting the system.
 E.g. Lights going on or off.

6.  A decision allows you to choose two different
outcomes based on a question.
 E.g. If the light is green, go. If the light is not
green, stop.

7. Which symbol would you use for:
• Start
• Pick up the box
• Turn light bulb on
• Do you want milk in your tea?
• Stop
• Turn light bulb off

8. you’ve finished.
START
With a partner,
fill in the
empty boxes
to make a cup
of tea!
Milk?
Drink tea
Boil water
Sugar?
Put teabag in cup
Add water to kettle
Add sugar and stir
Pour water into the teacup
Pour milk into the teacup
STOP
Yes
No
No
Yes

9. We can drag and drop
these symbols to create
our own flows.

10.  A mimic is a controllable picture.
We can control the
lights in this Mimic
e.g. turn them on
and off.

11. Use the worksheet to create a
flow to control a Zebra crossing.
