WHAT IS AN ALGORITHM? ,[object Object]

Examples of algorithms: ,[object Object],[object Object],[object Object],[object Object]

A flow chart ,[object Object],[object Object],[object Object]

Process shapes… START / END Human process i.e. you doing something! Input or output Query / question Printed output Save to file Yes No Remember not to create the flow chart in WORD… Instead do this in POWER POINT and change File – Page Layout to PORTRAIT Autoshapes has the shapes you need to use

More shapes ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Predefined process

TASK 1 MAKING A CUP OF TEA! ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Answers follow

Stir in sugar Add milk? Pour in milk Ready N N Now add the shapes…

Skills in Powerpoint to create your algorithm…. To tidy up the whole column… select all (drag around all shapes) Go to DRAW Select ALIGN or DISTRIBUTE To change this to ….
