  • read information from a graph
  • compare information within a graph
  • create a graph
    • label each axis
    • give the graph a title
    • use consistent measurements on the intervals
  • create a circle graph from data using a circle graph template

Some important vocabulary:

  • axis
  • interval
  • trend
