Elaboration on this Achievement Objective

This means students will critically consider comments made by others, usually their classmates, by referring to the features of displays on which the person is making claims. These displays will be showing either category data (pictographs, bar, strip, and pie graphs) or whole number data (dot plots or stem and leaf graphs). Students should also consider whether the chosen display/s best shows patterns in the data, for example strip and pie graphs show proportions well, pictographs and bar graphs show differences well.

Units of Work
In this unit students make statements about data displays. Students evaluate statements as true or false using the features of the data to support their evaluation.
  • Make a statement about a data display.
  • Decide if they agree or disagree with a statement about the data display.
  • Give reasons to support their evaluation of the statement.

Words

Level Two
Statistics
Units of Work
The purpose of this unit is to develop students’ understanding that texts have different language features, depending on their purpose. Students learn about words in texts by conducting a statistical investigation, and by using their data to answer the question they pose.
  • Suggest an investigative question.
  • Plan and carry out an investigation. (Collect, sort and display data, communicate findings based on data and draw conclusions.)
  • Sort words by category and justify their classification.
  • Create a pictograph and correctly name (word) categories.
