Learning Objectives To learn how to break down tasks How to create a flowchart

Turn to page 4 Start End The first and last part of a flowchart must have and Any rectangles are processes (where you do something) Enter Room Switch Light On Sit Down A diamond is a decision box. You have to make a choice – yes or no. Is it dark? Finally, it goes in the same order as time END SIT DOWN SWITCH LIGHT ON IS IT DARK? ENTER ROOM START

So what is it? A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows.

What do these represent? End Start

What do these represent? Process

What do these represent? Decision

Task List all the ‘tasks’ for making tea / coffee Pg200 (on the left)

Task Now make a flowchart on this. Pg200 (on the right)

Systems Flowchart Shows more detail than a programs flowchart Shows input / output and hardware.

1.Finish flowcharts problems Print them. 3. Find the file copy this into page 203 (second box). 4. Label the parts. 5. Explain what the system is doing. 6. Revision (see me for tasks)
