Data Through Pictures
Class 5 · Mathematics
5 ideas in Class 5 Mathematics, explained in plain words, with games and quizzes to practise.
Collecting Data with Records
Part of: Recording and Collecting Data
When you want to know something about a group of people or things, you ask questions and write down the answers. You can use pictures, marks or symbols to keep a record of each answer. For example, asking your friends how many books they read makes a list of answers that you can organize.
Why it matters. Collecting data teaches you how information is gathered. It helps you see patterns and make decisions based on facts instead of guesses.
Try it in two minutes
- Ask your family members how many glasses of water they drink in a day. Use a tally mark for each person.
- Count the total tally marks and tell how many people you asked.
- Ask a different question and collect data again with a new list.
Try at home. Ask your friends what fruit they like best. Make a list with marks or symbols for each choice and count the total.
Using Pictographs with Scales
Part of: Pictographs and Scales
A pictograph uses small pictures or icons to show numbers of things. When there are many items, one icon can stand for more than one thing. For example, one car symbol might mean 5 real cars, so 3 car symbols mean 15 cars. The scale tells you how many items each icon represents.
Why it matters. Pictographs make large amounts of data easier to see and compare. A scale helps show lots of items without drawing too many pictures.
Try it in two minutes
- Show your child a pictograph where one icon represents 10 items. Draw 2 icons and ask how many items that shows.
- Ask them to find how many icons you need to show 40 items if each icon means 10.
- Make your own pictograph together showing how many days you exercise each week.
Try at home. Collect data about how many hours your family members sleep. Draw one circle for every 2 hours and show the pictograph.
Reading Pictographs and Extracting Information
Part of: Reading and Interpreting Data
To read a pictograph, first check the scale to learn what each icon means. Then count the icons in each row or group and multiply by the scale value. Compare rows to find which has more or less, and add rows to find totals.
Why it matters. Reading pictographs teaches you to extract and compare real information. It helps you answer practical questions like which product sells most or which day had the most visitors.
Try it in two minutes
- Draw a pictograph with one circle meaning 2 pets. Show 3 circles for cats and 5 for dogs.
- Ask your child: how many pet cats are shown? (3 × 2 = 6)
- Ask: which row has more pets? By how many?
Try at home. Create a pictograph of your family's favorite foods using one square for 2 servings. Write questions about it and answer them together.
Creating and Reading Bar Graphs
Part of: Bar Graphs and Data Display
A bar graph uses rectangular bars to show data. Each bar's height tells you how many items or how much of something there is. All bars are the same width. The taller the bar, the greater the quantity. A number scale on one side helps you read the exact values.
Why it matters. Bar graphs make it easy to compare amounts at a glance. They help you see which items are most and least popular, or how quantities change.
Try it in two minutes
- Draw a simple bar graph showing how many hours you sleep, study, and play each day.
- Make the bars different heights based on the actual hours.
- Ask your child: which bar is tallest? What does it show?
Try at home. Create a bar graph showing temperatures for 5 days. Measure each day and draw proportional bars to compare.
Data Collection from Real Situations
Part of: Collecting Real-World Data
Real data comes from measuring, counting or observing actual things around you. It might be the length of your friends' fingers, the temperature each day, or how much food is wasted. You collect this data, record it, and then display it in a pictograph or bar graph to find patterns and answer questions.
Why it matters. Working with real data helps you see why data collection and display matter in real life. You learn to measure carefully, organize information, and draw conclusions from what you observe.
Try it in two minutes
- Measure the height of each family member in centimeters.
- Write down all the heights.
- Draw a bar graph with each person's name and bar height matching their measurement.
Try at home. Collect data on how much your family uses different types of transport in one week. Make a pictograph or bar graph to show the results.
