NCERT Solutions for Class 3 Maths Chapter 13 – Smart Charts deals with data handling. The introduction of data handling is a very important area in Maths. By the end of primary school, children must be able to collect and record data and present it in the form of bar charts and tables. Children must also be to recognize patterns in the data and draw conclusions.

Observation

Observation means keeping our eyes and ears open when we look at objects around us and notice various features in an object such as its shape, colour, size, etc. Observation is very important. We have to collect information about an object. If we don’t observe properly then we can miss out on some important aspects of the object and our recording of the information will be incomplete.

How Do We Classify Things?

Classifying things means to collect things, and then group them as per their common features. We are sorting things based on colours or shapes or sizes or counts, etc. In simple words, we are collecting information about things and then sorting them out.

Data Handling

When we gather information and record them so that we can present them to others in a very meaningful way, it is called data handling. In other words, making a note of the data collected is called data handling.

There Are Various Ways of Collecting Data

Tally Marks
Pictorial Representation
Bar Chart

Tally Mark: A tall mark is counting the objects or activities in the group of 5. A single vertical line represents an object. To mark the tally, we draw 4 vertical lines and the fifth line obliquely cuts through the four vertical lines. Tally mark is the quickest and easiest way of recording data.

Pictorial Representation: It is the presentation of information in a visual form.

(Image to be added soon)

The above picture is called pictorial representation. In the picture, you can see that different kinds of fruits are classified as per shape and variety.

Conclusion

From this lesson, students have learned a very important topic in Maths. In our daily life, we use the concept of data handling in almost everything. We keep a record of our books, toys, etc. It is important to recognize the patterns of objects that we see around and then draw inferences. This topic builds the fundamental concept of collecting records, which is going to be helpful in higher classes.
