Data Handling & Probability
In Grade 3, students develop their ability to collect, organize, display, and interpret data, as well as understand basic probability concepts. They learn to formulate questions, gather relevant information, create various representations of data, and make predictions based on data and probability experiments.
Grade Three Expectations for Data Handling & Probability
Essential Learning Outcome 1: Understanding Data Collection, Organization, and Representation
- Formulate questions for data collection and determine appropriate methods
- Collect and organize data using tally charts and frequency tables
- Create pictographs and bar graphs with appropriate scales and labels
- Construct line plots to display measurement data
- Read and interpret data from various representations
- Find the mode and median of a data set
- Draw conclusions and make predictions based on data
Specific Curriculum Outcomes
By the end of Grade Three, the learner will be expected to:
Inclusive Assessment Strategies
Assessment strategies that provide information about learning:

Teacher Content Knowledge
Data Handling and Probability in Grade 3 builds upon students' earlier experiences with sorting, classifying, and simple data representation. Students develop more sophisticated skills in collecting, organizing, displaying, and interpreting data, as well as a deeper understanding of probability concepts. They learn to formulate questions, gather relevant information, create various representations of data (including pictographs, bar graphs, and line plots), and make predictions based on data and probability experiments. Through hands-on experiences and real-world applications, students develop data literacy and an understanding of how data and probability are used in everyday life.
