Overview: The Data Management and Analysis section for Grade 4 in the Kawartha Pine Ridge District School Board focuses on helping students manage, analyze, and use data to make informed decisions. The curriculum emphasizes understanding the differences between qualitative and quantitative data, collecting and organizing data, visualizing data through various types of graphs, and analyzing data to draw conclusions.
Main Subsections:
Data Collection and Organization:
Specific Expectations: Students learn to describe the difference between qualitative and quantitative data, collect data from primary and secondary sources, and organize data in frequency tables and stem-and-leaf plots.
Example Problem: "Collect data on the favorite fruits of your classmates and organize it using a frequency table."

Video Resource: Primary vs Secondary Data
Data Visualization:
Specific Expectations: Students select and use appropriate graphs, such as bar graphs and pictographs, to display data. They learn to justify their choice of graphs and ensure proper sources, titles, and labels.
Example Problem: "Create a bar graph showing the number of books read by students in your class over the month."

Data Analysis:
Specific Expectations: Students analyze different sets of data by identifying measures of central tendency such as mean, median, and mode. They also interpret the data to make convincing arguments and informed decisions.
Example Problem: "Calculate the mean and median of the test scores in your class and discuss what these measures tell you about the overall performance."

Interactive Data Tools: Online platforms like Google Sheets or Microsoft Excel can be used to practice organizing and visualizing data.
Class Activities: Conduct surveys or simple experiments (like measuring plant growth under different conditions) to collect and analyze data.
Games and Quizzes: Incorporate educational games that focus on data management skills, such as creating and interpreting graphs.
This integrated approach helps students not only understand the technical aspects of data management but also appreciate its practical applications in everyday life.
