Introduction to CBSE Solutions for Class 5 Mathematics: Smart Charts
The chapter “Smart Charts” engages Class 5 students with the fundamental concepts of data handling by teaching them to compile, organize, and represent data visually. Students learn about different kinds of charts such as bar charts, pie charts, and tally charts, each serving as a tool to convey information clearly and efficiently.
Learners are introduced to the process of collecting data and representing it in a structured format that can be easily understood and analyzed. The chapter encourages students to create their own charts based on data they gather from their surroundings, such as the number of vehicles passing by a street, the different types of plants in a garden, or the varieties of fruits in a market.
Through various exercises, students understand the significance of each type of chart and how to choose the appropriate one depending on the data. They also grasp how to interpret the given information and draw conclusions from it, a skill that is increasingly important in a data-driven world.

Questions and Answers for CBSE Class 5 Mathematics: Smart Charts
- Q1: What is a bar chart?
ANS: A bar chart is a graphical representation of data where bars of different lengths are used to show the comparison among categories. - Q2: How is data represented in a pie chart?
ANS: In a pie chart, data is represented by dividing a circle into slices that reflect the proportion of each category in the whole set of data. - Q3: What is the purpose of a tally chart?
ANS: A tally chart is used to record and group counts in an organized way, often in sets of five for easy summation. - Q4: When should you use a bar chart instead of a pie chart?
ANS: A bar chart is more suitable when you need to show the difference in size among categories, especially when there are many categories or when the differences in data are not too stark. - Q5: Can you represent time data on a bar chart?
ANS: Yes, time data, such as the amount of time spent on various activities, can be represented on a bar chart. - Q6: How do you determine the size of a slice in a pie chart?
ANS: The size of a slice in a pie chart is determined by the percentage or fraction of the total that the category represents. - Q7: What information is needed to create a chart?
ANS: To create a chart, you need collected data organized into categories, along with the frequency or amount for each category. - Q8: How can charts help us in daily life?
ANS: Charts help us organize information, compare different sets of data, and visualize patterns and trends in daily life. - Q9: What are the advantages of using charts?
ANS: Charts present data in an easy-to-understand format, making it simple to compare information and draw conclusions quickly. - Q10: How can we make sure our chart is ‘smart’?
ANS: A ‘smart’ chart is accurate, clear, well-organized, easy to read, and correctly represents the data it is based on.
