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).
Primary: Data Management and Probability
- Collect and organize categorical primary data and display the data using concrete graphs and pictographs, without regard to the order of labels on the horizontal axis.
- Read and describe primary data presented in concrete graphs and pictographs.
- Students begin by sitting on the carpet in a circle.
- Students will move to tables to work on their Smarties Graph.
- Smarties graph package (Appendix A – download)
- Small boxes of Smarties – at least one for each child
- Pencils and erasers
- Explain that each student will be getting a box of Smarties and sorting them by colour.
- Ask students to place each Smartie on the graph according to the colour.
- Ensure students have sorted the smarties by colour.
- Have students take each column off one at a time and colour the boxes in with the corresponding marker colour (e.g. a student would colour 3 boxes in if they received 3 red Smarties).
- Once their graphs are complete, ask students to answer the questions about their box of Smarties (e.g. How many red Smarties did you have? Which did you have the most of?)
- Ask students to compare their graph with another classmate.
- Can the child sort by colour?
- Can the child accurately count the number of Smarties in each column?
- Does the child interpret the data correctly?
