Mathematics Class 1 - Logical Reasoning Notes

Logical Reasoning

Welcome to the chapter on Logical Reasoning for Class 1. In this chapter, you will learn how to think carefully, find patterns, and solve simple puzzles. Logical reasoning helps you become a better problem solver!

Introduction

Logical reasoning means using your mind to solve problems and answer questions. It helps you to think clearly and make good decisions.

Key Concepts

• Pattern: Something that repeats in a certain order.
• Sequence: Things arranged in a special order.
• Grouping: Putting things that are alike together.
• Odd One Out: Finding what is different in a group.

1. Patterns

Patterns are things that repeat in a certain way. Look at the shapes below:

Example: Circle, Square, Circle, Square, Circle, ?
What comes next?
Answer: Square

2. Sequences

A sequence is a list of things in a special order.

Example: 1, 2, 3, 4, ?
What comes next?
Answer: 5

3. Grouping

Grouping means putting things that are the same together.

Example: Put all the red balls together and all the blue balls together.

4. Odd One Out

Sometimes, one thing in a group is different from the others. That is called the "odd one out."

Example: Cat, Dog, Lion, Banana
Which is the odd one out?
Answer: Banana (because it is not an animal)

Fun Activity: Find the Pattern!

Draw a pattern using shapes or colors. Ask your friend to guess what comes next!

Summary

• Logical reasoning helps you solve puzzles and problems.
• Patterns repeat in a certain way.
• Sequences are things in order.
• Grouping means putting similar things together.
• Odd one out is finding what is different.

Practice Questions

1. What comes next: Red, Blue, Red, Blue, Red, ?
2. Which is the odd one out: Apple, Mango, Car, Banana?
3. Put these in order: 2, 4, 3, 1
4. Group these: Cat, Dog, Ball, Bat
5. What comes next: 5, 6, 7, ?

Challenge Yourself

• Make your own pattern using colors or shapes.
• Find three things in your house that are the same and group them together.

Did You Know?

• Detectives use logical reasoning to solve mysteries!
• Patterns are everywhere—in music, art, and nature!
