  • Alternatively, complete the dcform2 from lesson 4
  • Go through the answers with them. They could copy the data types table in WORD
  • Text, date, currency, number, text, image, number, currency
  • Remind students about the data collection form they created last lesson. Remind them about the field names, they should recognise them. Ask them to identify the most appropriate datatypes for each field.
  • Teacher demonstration Explain that a database has already been created with records of many Superheroes and Supervillains. Explain that this is to ensure that there is enough data for them so that they can create queries later on. Show students how to make a copy of the database ‘filmcharacters.mdb’ and save it in their area Demonstrate how to open the ‘characters’ table and show them the difference between design and datasheet view and how they can go between the two views. Point out the field names and the datatypes in design view. Explain the difference between the two views. Datasheet view displays the data stored in the table – you can edit fields, add and delete data. Design view you can create an entire table from scratch, or add, delete, or customize the fields in an existing table. Point out how they can tell how many records are stored in the database. Show them how to enter a new record directly into the table.
  • Individual task Ask students to

    • Understand: . Which is the most appropriate datatype for different fields
    • Be able to: enter data into a database via a table and a data entry form.
  • 3. Starter
    • Using the data capture forms created last lesson.
      • Complete with details about 4 team members (super hero team) and/or henchmen (super villain team)
  • 4. Datatypes exercise
    • Students to log on and access the ‘datatypes’ file
      • POOL Students ICT ks3 7 DataHandling L5
    • Hand out copies of ‘datatypes_task.doc’
    • Datatypes
      • The characteristic of a field that determines what type of data it can hold. E.g. Boolean, Integer, Long, Currency, Single, Double, Date, String.
    • Find out about the different datatypes and complete the task sheet.

      • Name
      • Role
      • Ability 1
      • Ability 2
      • Ability 3

      • Switch between the design and datasheet view by clicking the and the buttons.
  • 8. Task
    • Enter the details from your four data collection forms into the ‘characters’ table.
  • 9.
    • How easy did you find it to enter data into the table.
