  1. Tables and Graphs Primary 4 Mathematics

  2. Chapter Learning Outcomes • Representing data in tables, bar graphs and line graphs

  3. Tables, Bar Graphs and Line Graphs Diana counted the number of cars that drove past a junction and noted down their colours.

  4. Tables, Bar Graphs and Line Graphs I can use a bar graph to represent this.

  5. Bar graphs • A bar chart uses bars to show comparisons between categories of data. These bars can be displayed horizontally or vertically. 

  6. Example The bar graph shows the products sold at a bakery.

  7. Example Complete the table with the information in the bar graph. 29 17 10 17 13 21

  8. Example Answer the questions below: Which product was least popular? Pies

  9. Example Answer the questions below: Which two products had the same number sold? Tarts and strudels

  10. Example Answer the questions below: What was the total number of products sold? 107 items

  11. Tables, Bar Graphs and Line Graphs Benjamin planted a seedling and measured its height over 6 weeks. I can use a line graph to represent this.

  12. Tables, Bar Graphs and Line Graphs I can see the amount of change over a period of time based on the line graph.

  13. Line Graphs • Line graphs are used to display continuous data. It shows trends over time or relationships between two quantities.

  14. Example The line graph shows the number of books sold at a book store last week. Answer the following questions:

  15. Example Between which 2 days was there the greatest increase in books sold? Thursday to Friday

  16. Example How much was the decrease in books sold from Monday to Tuesday? 1500

  17. Example What was the total number of books sold in that week? 30 000 books

  18. Time to wrack your brains! • What are the main differences between a bar graph and a line graph? • When do we use a line graph or a bar graph?
