Solving simple problems

What are problems?

‘Which blouse should I wear?’

‘I want this toy!’

‘Which way should I turn it?’

What other problems have you faced before?

‘I do not like to eat vegetables.’

‘It is not beautiful.’

‘I am very hungry.’

There are things that are difficult to deal with. We call them problems.

Solving simple problems There are a few ways we can use to solve some simple problems.

Trial and error There are two keys. Which key opens the door?

Firstly, we will try with the key that we think will open the door.

!?

What happens if it does not open the door? What will you do next?

Chapter 1

Solving simple problems

3

If it cannot open the door, then we will try with the second key.

What should you do if there are more than two keys?

You may have to try all the keys to find the correct one. You need to have some patience.

This method of problem solving is known as trial and error. You always try with the option that has the best chance of success.

1 There are 3 padlocks and 3 keys. How will you find out which key opens which padlock?

Draw how you will solve this problem. How do you make sure that you do not repeat the same key with the same padlock?

Mazes are fun to play with. We have to try almost every path to find the correct one to reach the end point or the destination.

2 Help Penguin to get the ice-cream. Which path will you take? Draw on it.

1. Did you manage to get the ice-cream on the first try?

2. Did you manage to get the ice-cream on the second try?

3. Was it fun?

To solve a maze, we need to find a path through the maze from the starting point to the end point. You cannot go over the walls of the maze.

Starting point

End point

When solving a maze, always use the trial and error method. Try to take the path that we think will most probably succeed. If it is not successful, try other paths.

Try again if you did not succeed.

Do not give up easily!
