The flowchart is a visual representation of data. Here students will learn about flowcharts, the uses of flowcharts, the symbols used in flowcharts, and how to make a flowchart. That also connects students with the mathematical concept of reading time, 2d shapes, points and lines.

Flowchart Maker

Flowcharts were first developed by Herman Goldstone and John von Neumann in the 1940s for computer programming.

What Is a Flowchart?

A flowchart defines the separate steps of a process in sequential order. It can be used for various purposes and can describe multiple methods.

A flowchart includes

  • Sequence of actions
  • Materials or services entering (Inputs) and leaving the process (outputs)
  • Decisions making
  • Results related to that decision.

Uses of Flowchart

There are various uses of flowcharts, some of which are discussed below.

  • Flowchart helps to understand how a process is done.
  • It helps to study any process for improvement of that process.
  • Also, using a flowchart, it is easy to communicate with others to get the process done quickly.
  • Flowchart helps in planning a project well.
  • Flowchart is used in algorithms, audits, programs, projects, troubleshooting, etc.

Symbols Used in Flowcharts

In flowcharts, different shapes are used to represent different types of actions. Lines and arrows show the sequence of the steps. These are called flowchart symbols.

How to Make a Flowchart?

Before starting to draw a flowchart, one should write down its algorithm first. Then,

  1. First, write a title at the top of the flowchart.
  2. Then discuss and decide the boundaries of your process. Also, where and when to start or end the process.
  3. Arrange the activities in proper order.
  4. After properly adding all activities, connect the actions with arrows after everyone agrees with the order of the activities.
  5. Review the flowchart with others involved in the process.

Reading Time

Question 1:

Here Is a Flowchart of a Machine to Say ‘Good Morning’.
Flowchart to Say Good Morning:

Flowchart diagram

Now Look at the Given Below Times Carefully and Answer if the
Machine Will Say Good Morning or Not at Those Times.
(i) 10 AM (iii) 8 PM
(ii) 5 PM (iv) 6 AM


First, we must decide when the machine will say ‘Good morning.
Steps to make a flowchart:

  1. We know that one should wish good morning always before noon. Noon is considered after 12 PM. (Process)
  2. If the time is after noon, one should not wish good morning. (Decision)
  3. If the time is before noon, one should wish good morning.
  4. If yes, the machine will print good morning. If not, then the device will end the process. (Output)

(i) 10 am comes before noon. So, according to the flowchart, the machine will print good morning at 10 am.

(ii) 8 pm comes after noon. So, according to the flowchart, the machine will not print good morning at 8 pm.

(iii) 5 pm comes afternoon. So, according to the flowchart, the machine will not print good morning at 5 pm.

(iv) 6 am comes before noon. So, according to the flowchart, the machine will print good morning at 6 am.

Question 2:

Look at the Below Flowchart. The Flowchart Is About the Routine Sonali has After Returning From School. Draw the Hands on the Clock from the Flowchart in the Given Picture. Also, Find the Time Gap Between Her Activities.

Reading time


First, we need to discuss the flowchart. From the flowchart, it is clear that

(i) Sonali comes back from school at 4: 30 PM.

(ii) Sonali is playing at 5: 00 PM.

(iii) Sonali is studying after 5: 00 PM.

Let us assume that Sonali studies around 6: 45 PM.
Sonali comes back from school at 4: 30 PM, plays around
5: 00 pm and studies around 6: 45 pm. In the below picture, it is shown.

Reading time

The time gap between her activities is
5: 00 – 4: 30 = 30 minutes
6: 45 − 4: 30 = 2 hours and 15 minutes.

2d Shapes in Maths

Question 3:

The Teacher Asked the Students of Grade 3 to Identify the Symbols of the Flowchart, Which Resemble With Shapes They Have Read. What Will Be Their Answer?


In grade3 students only know these figures
Triangle, Square, Rectangle, Circle
These are resembled with

2D shapes

Points and Lines

Question 4:

Samuel and Daniel Were Playing a Game. They Have Drawn All the Symbols on the Flowchart. The Game’s Rule is that they have to Mark With a ✓ tick if the Symbol Has a Corner and Mark With a 🗴 Cross if It Doesn’t Have Any Corner. Samuel Is Finding Pictures With Corners, and Daniel Is Finding Pictures With No Corners. Find How Many Pictures Each One of Them Could Find Below, Picture Following the Rules of the Game.

2D shapes


Their answer will be

2D shapes

So, Samuel found 6 pictures with corners, and Daniel found 2 without corners.

Question 5:

Nisha and Rupsha Are Playing a Game. Nisha Is Finding the Symbols With a Curve Line in the Below Flowchart, and Rupsha Is Finding the Symbols With Only a Straight Line in the Flowchart. Nisha and Rupsha Decided to Color Those Symbols Red and Blue, respectively. What Will the Picture Look Like?
