Curriculum
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).
Context
- Students begin by sitting in a circle. Students will move to tables to work on their circle and bar graph.

Materials
- Circle graph to bar graph package (Appendix A – download)
- Pencils and erasers
Lesson
- 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?
Extension
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.
