Age 7 guide to bar charts

Age-appropriate activities, explanations and practice ideas for bar charts.

Quick answer

Bar charts help us compare amounts by showing them as bars of different heights. At age 7, you'll learn to read and make simple bar charts to show information like how many toys you have or how many pets your friends have.

Learning outcome

By the end of this page, you will be able to:
  • Read bar charts to find out how many of each thing there are
  • Make your own bar charts to show simple information
  • Use bar charts to compare amounts easily
  • Understand that the taller the bar, the more there is

Why this matters

Bar charts help you understand information quickly. They're used everywhere – in newspapers, shops, science projects, and even when you're planning a party! When you can read and make bar charts, you'll be better at solving problems and making decisions based on data.

How it works

A bar chart has:
  1. Two axes (lines) – one horizontal and one vertical
  2. Bars that show amounts
  3. A title that tells what the chart is about
  4. Labels on both axes to show what each part means
To make a bar chart:
  1. Decide what information you want to show
  2. Draw your axes
  3. Label each axis
  4. Draw bars that match your amounts
  5. Add a title

Examples you can see

Let's look at a bar chart showing how many pets different children have:
Child Pets
Alice 3
Ben 1
Carla 5
David 2
This chart shows:
  • Alice has 3 pets
  • Ben has 1 pet
  • Carla has 5 pets
  • David has 2 pets
You can see that Carla has the most pets and Ben has the least.

Try it as a mini adventure

Adventure: Pet Survey Challenge You are a pet detective! Your mission is to find out how many pets each child in your class has and then create a bar chart to show the results.
  1. Ask 5 friends how many pets they have
  2. Record their answers
  3. Draw a bar chart with the names on the bottom and number of pets on the side
  4. Find out who has the most pets and who has the least

  • Gina: 3 pets
  • Harry: 2 pets
  • Ivy: 5 pets
Draw a bar chart with these numbers and see who wins the "Most Pets" prize!

Common mistakes

  • Mistake: Thinking that the bar with the most space at the top means it's the highest bar.
    Why it happens: Looking at the chart from the wrong side.
    Fix: Remember that the bar that reaches highest on the chart is the one with the most items.
  • Mistake: Not checking that the numbers on the side match the bar heights.
    Why it happens: Not reading carefully.
    Fix: Read each bar and its number carefully, like a detective.
  • Mistake: Drawing bars that are too tall or too short.
    Why it happens: Not counting the numbers properly.
    Fix: Count the numbers carefully and make sure each bar reaches exactly the right height.

Parent and carer guide

How to help your child at home:
  1. Ask your child to explain how to read a bar chart they made
  2. Use everyday situations like shopping or cooking to make charts
  3. Let them create charts for their toys, books, or pet collections
  4. Encourage them to compare amounts using the bars
  5. Ask questions like "Which bar is the tallest?" or "How many more does this have than that?"
What to watch for:
  • Does your child understand that bar height shows amount?
  • Can they read the numbers on the side correctly?
  • Do they make bars that match the correct heights?
What not to worry about:
  • They might mix up bar heights at first – this is normal
  • They may not understand all chart details right away
  • They'll improve with practice and more examples
