Data… Data is raw facts and figures. Data on it’s own has no meaning. Some examples: a3z B2.2 d2d4 wig
Data Types Data comes in many different forms. It could be all stored in the same way but it wouldn’t be very useful. This is why we have Data Types.
Task 1 Open the “What are Data Types” PowerPoint from the shared area. Read it…
Task 2 Either create a mind map / spider diagram or traditional plain old notes in your book about each data type. You must include the name of the data type, a description and an example. Extension: find out WHY each data type is needed.
Task 3 Complete the worksheet you have been given. This will be completed for homework if you don’t finish it during the lesson. Stick the worksheet in your book.
Plenary Without looking in your book… Explain to the person sitting next to you what a data type is… Then swap over so the other person can explain two reasons why selecting the correct data type is important. Write your answers down in your book.
