Circle to Bar Graph

Early Years
Age 3-6


Kindergarten: Demonstrating Literacy and Mathematics Behaviour

  • Collect, organize, display, and interpret data to solve problems and to communicate information, and explore the concept of probability in everyday contexts (#19). 


  • Students begin by sitting in a circle. Students will move to tables to work on their circle and bar graph. 


  • Circle graph to bar graph package (Appendix A – download)
  • Pencils and erasers


  • Show students the circle graph and explain that this is another way to display information.
  • Students will be transferring the circle graph information into a bar graph as a bar graph communicates information more clearly.
  • Have students go to different tables and work on translating the circle graph into a bar graph.
  • The last page of the circle to bar graph package will have questions about the graph.
  • For example: How many more squares did you have than triangles?
  • When students finish filling in the graphs, they can practice asking each other questions about the graph. 

Look Fors

  • Can children translate the information from the circle graph onto a bar graph?
  • Are children able to come up with questions about the information in the bar graphs to ask other students?


Tooth Graph

  • Have a tooth graph going throughout the year. A magnet with each student’s name on it can be used to represent who has lost a tooth.
  • As a child loses a tooth, they can update the graph.

Circle Weather Graph

  • This works best in the month of November because in Canada that is typically when we observe the most diverse weather.
  • Each day look out the window and put a mark in the appropriate weather section.
  • Have students predict which type of weather they will get the most in November.

Siblings Graph

  • In small groups, build a sibling graph.
  • Ask students how many siblings they have and have them put their mark in the appropriate section.
