This unit builds on Unit 4D 'Collecting and presenting information: questionnaires and pie charts' and Unit 3C 'Introduction to databases'.
The unit assumes that children:
- know that data can be collected and represented in different formats, eg tables, pictograms, bar charts, pie charts
- understand that data needs to be sorted and organised so that information can be found easily
- know that data records consist of fields into which data is entered
- can sift and skim read information.
