## What do I need to Learn?

 I need to learn how to Identify flowchart symbols and understand how they are used to describe systems I need to learn how to break down problems and processes into distinct steps. I need to learn how to develop a control flowchart solution for a simple problem

## Lesson

• We are going to save all of our work for this topic into a PowerPoint, that will have a menu like our spreadsheet user interface.

• ## Using flowcharts to create Algorithms

Computers follow instructions or sequences programmed into them.

A flowchart can be used to help design a sequence or Algorithm. Actions can be ordered, reordered or removed if no longer necessary.

• Compare these symbols with the ones we will be using in the flowchart program flowol
• .

Make sure you memorise these symbols as they will be part of the assessment. You could screenshot them into your PowerPoint.

## Sequencing an Algorithm

There are several aspects of control Algorithms but all of them involve controlling computers and creating sequences of instructions for the computer to follow.

Control technology is used to:

• operate systems, eg traffic lights
• control actions, eg a robot's movement
• create video games
• control manufacturing devices, eg laser cutters

• ## Getting to know Flowol

Read through the slides below and follow the instructions to create a Zebra crossing flow diagram using Flowol.

• ### Summing it all up

Lets look at the learning outcomes and decide which one best describes our current level of understanding :

Tick the one you feel is closest to your level

## Learning Outcomes I need to learn how to Identify flowchart symbols and understand how they are used to describe systems

• I have a basic understanding of how I can Identify flowchart symbols and understand how they are used to describe systems with a little help from my teacher
• I can show my teacher that I can Identify flowchart symbols and understand how they are used to describe systems without their help.
• I can Identify flowchart symbols and understand how they are used to describe systems independently and I can also explain it to others and can complete any extension tasks I am given.
