Picture & Bar Graphs

Mathematics · Data & Statistics · representational

Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories; solve put-together, take-apart, and compare problems using information presented in a bar graph

What mastery looks like

  • Draw a picture graph with a symbol representing one unit for each data point
  • Draw a bar graph with labelled axes and a single-unit scale
  • Use a bar graph to answer comparison questions (e.g. 'How many more votes did cats get than dogs?')

Check your understanding

Can Picture & Bar Graphs draw a simple bar chart or picture graph to show information — like how many of each colour of sweet are in a bag — and answer questions from it?
