Making Groups and Sorting
Making groups means putting things that are alike into the same set. Sorting means arranging things by a rule — like colour, size, shape, or type.
In Class 1, children sort everyday objects like fruits, toys, animals, and shapes. Sorting helps children observe, compare, and organise things around them.
What is Making Groups and Sorting - Class 1 Maths (Data Handling (Grade 1))?
Making groups (or classifying) means deciding a rule and putting objects that follow that rule together.
Common rules for sorting:
- By colour: Red things, blue things, green things
- By size: Big things and small things
- By shape: Circles, squares, triangles
- By type: Fruits, vegetables, animals, toys
- By use: Things to eat, things to wear, things to play with

Example 4: Example 4: Count in Groups
Question: Ria sorts buttons: 5 red buttons and 3 blue buttons. How many buttons in total?
Think:
- 5 + 3 = 8
Answer: There are 8 buttons in total.
Example 5: Example 5: Odd One Out
Question: Apple, mango, banana, car. Which does not belong?
Answer: Car does not belong — the rest are fruits.
Example 6: Example 6: Sort Shapes
Question: Sort: 2 circles, 3 triangles, 1 square, 2 circles. How many circles?
Answer: There are 4 circles (2 + 2).
Example 7: Example 7: More Than One Way
Question: Big red ball, small red ball, big blue ball. Sort by colour, then sort by size.
Answer:
By colour:
- Red: big red ball, small red ball
- Blue: big blue ball
By size:
- Big: big red ball, big blue ball
- Small: small red ball
Key Points to Remember
- Making groups means putting similar things together.
- We can sort by colour, size, shape, type, or use.
- The same objects can be sorted in different ways.
- After sorting, we can count how many are in each group.
- Sorting helps us organise and understand information.
Practice Problems
- Sort these into fruits and animals: dog, orange, cat, grape, parrot, apple.
- Sort by colour: green leaf, red apple, green frog, red rose, green parrot.
- Which does not belong: pencil, pen, eraser, mango?
- Sort by size: elephant, mouse, whale, ant.
- Aman has 4 red marbles and 6 blue marbles. How many marbles in total?
- Sort these shapes: circle, triangle, circle, square, triangle, circle. How many circles?
Frequently Asked Questions
Q1. What does making groups mean?
Making groups means choosing a rule (like colour or type) and putting things that follow that rule into the same group.
Q2. How many ways can I sort the same objects?
You can sort the same objects in many ways — by colour, by size, by shape, by type, or by use. Each way gives different groups.
Q3. What is an odd one out?
An odd one out is one thing in a group that does not match the others. For example, in apple, mango, banana, car — car is the odd one out because the others are fruits.
Q4. Why is sorting important?
Sorting helps children learn to observe, compare, and organise. It is a basic skill used in maths, science, and everyday life.
Q5. Can I sort things at home?
Yes. You can sort toys by size, clothes by colour, books by thickness, or groceries by type (fruits, vegetables, snacks).
Q6. What is the difference between sorting and counting?
Sorting means arranging things into groups. Counting means finding how many. You can sort first and then count how many are in each group.
