Data handling

itp_data_handling.png

This interactive teaching program (ITP) is an ICT-based tool to support the exploration of data. Data handling ITP allows the child or teacher to enter data into a table and then create a vertical bar chart, a horizontal bar chart or a pie chart. The user can select from existing datasets, which can then be amended to show the impact and change on the charts, or they can enter collected data.

Opportunities to use and apply

Possible contexts include:

  • collecting examples of pie charts representing data related to cross-curricular work and children’s interests, e.g. from newspapers, magazines and the internet;
  • using spreadsheet programs to create pie charts, setting questions for other children to answer.
 

Confirming learning

Ask probing questions such as:

  • Do you think this bar chart and pie chart represent the same set of data? Explain your answer.
