Lesson 25 — Activity 1:

A Review of Tables


Using tables to display information can help you to see the data you are using in a different way. A table is a set of data (like numbers or quantities) that are arranged in rows and columns.

You can arrange any type of data into a table. For example, let's look at the table below. This table shows how many males drive SUVs and sports cars compared to how many females drive SUVs and sports cars.


As you can see from the table below, there are two totals in this table. If you add the numbers going across, you get the row totals (how many males altogether and how many females altogether.) If you add the numbers going down, you get the column totals (how many drivers of SUVs in total and how many drivers of sports cars in total.) This is just one way to display information in a table.


Now let's practise reading data from a table.

Look at the table below and then answer the questions that follow.


  1. How many sundae cones were sold on Tuesday?
  2. What was the total number of ice creams sold on Wednesday?
  3. How many more chocolate eclair bars were sold on Wednesday than on Monday? 
  4. What was the total number of crunch bars sold over the three days?
  5. How many more strawberry shortcakes were sold on Monday than on Wednesday?


  1. Twenty-three sundae cones were sold on Tuesday.
  2. There were 327 ice creams sold on Wednesday (121 + 137 + 17 + 35 + 17 = 327.)
  3. There were 59 more chocolate eclair bars sold on Wednesday than on Monday (137 – 78 = 59.)
  4. The total number of crunch bars that were sold over the three days is 48 (20 + 11 + 17 = 48.)
  5. There were nine more strawberry shortcakes sold on Monday than on Wednesday (130 – 121 = 9.)
