Reading Simple Charts
A chart is another way to show information. Charts can make data easier to see and compare.
A simple chart can show how many objects or people belong to different groups. We can look at the chart and answer questions about the information.
Learning Objectives
- Understand what a simple chart shows.
- Read information from a simple chart.
- Compare different groups.
- Answer simple questions using a chart.
Understanding a Simple Chart
A simple chart can use symbols or blocks to represent information. Each symbol or block can show a certain number of objects or people.
From the chart, we can see that there are more apples than bananas.
Reading Information from a Chart
To read a chart, look carefully at each group and count the symbols or blocks shown.
Question: Which fruit has the most?
Answer: Apples.
Question: Which fruit has the fewest?
Answer: Bananas.
Comparing Groups
Charts make it easy to compare groups. A group with more symbols represents a larger number, while a group with fewer symbols represents a smaller number.
There is 1 more apple than orange.
Using a Chart to Answer Questions
We can use the information shown in a chart to answer simple questions about most, least, more and fewer.
1. Which group has the most?
2. Which group has the fewest?
3. Which group has more?
4. Which group has fewer?
Common Mistakes
- Count every symbol carefully.
- Do not compare the wrong groups.
- Read the labels before answering a question.
- Make sure you understand what each symbol represents.
Practice
1. What does a chart show?
2. Which group has the most in this chart: Apple 4, Banana 2, Orange 3?
3. Which group has the fewest?
4. How many apples are shown?
Try It Yourself
Choose three types of fruit. Count how many of each type you have at home or can see around you. Draw a simple chart using one symbol for each fruit.
Quick Revision
- A chart shows information in a simple visual form.
- We can count symbols or blocks to understand the data.
- Charts help us compare groups.
- We can use charts to answer simple questions.
Next Step
You have completed Chapter 10. You now know how to collect, sort, organise and read simple information. These skills will help you solve more problems and think carefully about information in later mathematics lessons.
