Grade 4: What's the Story?
Data Science for Young Minds — Ages 9-10
Welcome!
In Grade 3, you learned to ask questions and collect data. Now it is time to make that data speak. Grade 4 teaches you to read graphs like a pro, find the average, spot trends over time, and understand the difference between what data shows and what it means.
This year you will work with real-world data — weather records, sports statistics, school data, and more. You will also begin using simple digital tools alongside your hands-on skills.
Reading Like a Pro
Go beyond making graphs — learn to read and interpret bar charts, line graphs, and pie charts with confidence.
Finding the Average
Learn what "typical" means in data. The mean (average) becomes your new superpower.
Spotting Trends
Is it going up? Going down? Staying flat? Learn to see the direction data is moving.
Real-World Data
Work with actual weather data, sports records, and school statistics — not made-up numbers.
Course Sessions
Reading Graphs Like a Pro
Master reading bar charts, line graphs, and pie charts. Learn what each part tells you and how to extract information quickly.
What Is Typical? The Mean
Learn to calculate the average (mean) and understand what "typical" looks like in a dataset. Discover when the average lies.
Trends Over Time
Learn to read line graphs, spot trends (up, down, flat), and make predictions about what might happen next.
Comparing Datasets
Compare two groups side by side. Which class read more books? Do boys and girls have different favorites? Learn to compare fairly.
Does This Cause That?
Ice cream sales and sunburns both go up in summer. Does ice cream cause sunburns? Learn correlation vs. causation.
Working With Real Data
Use actual weather records, sports statistics, or school data. Learn to find, read, and analyze data from the real world.
Introduction to Spreadsheets
Take your first steps with digital tools. Learn to enter data, calculate averages, and create graphs using a simple spreadsheet.
Your Data Report
Write a real data report: question, method, analysis, graphs, and conclusions. Present like a professional data analyst.
Tips for Families
- Point out data in the news. Weather reports, election results, sports scores — Grade 4 is when data in the real world starts clicking.
- Let them use real numbers. Grocery receipts, utility bills, and sports stats are more engaging than textbook examples.
- Ask "what's the story?" When you see a graph together, ask your child to tell you the story it is showing.
- Introduce spreadsheets gently. Session 7 uses simple spreadsheets. Google Sheets is free and works great.
- Celebrate the data report. Session 8 produces a real report. Treat it like a science fair project — display it proudly!
