What is Grouping?

  • Grouping is a set of people or things that have something in common. 

  • The action of putting things or arranging in a group or groups.

  • The collection can be grouped on the basis of size, shape, color, and a variety of other attributes.

What is Grouping? How do we group objects?

Grouping lets you rotate, flip, move, or resize all shapes or objects at the same time as though they were a single shape or object. You can also change the attributes of all of the shapes in a group at one time, such as adding a shape fill or effect, or an effect to a picture.

Different types of Grouping

  • Grouping by Number

Making groups of required numbers as illustrated like groups of 5, 10, 2, 4.

  • Grouping by Type

  1. Going by the definition of grouping, similar items need to be arranged together.

In the given example the source has all the alphabets mixed up

Our task is to put ‘A’s together, ‘B’s together, and ‘C’ s together as shown in the results.

So the outcome of this exercise is that we have separate groups of A B and C.

  1. The below example illustrates the grouping of the collection of food we daily take on the basis of Grains, Dairy, Fruits + vegetables, and Protein.

So all the food items which are made of grains like bread and porridge goes into the group ‘Grains’.

Items made out of milk are put under ‘Dairy’. Banana, cauliflower, etc are in ‘Fruits and Vegetable’. 

Meat and Poultry go in ‘Protein’. 

One can see how the items with similar properties and composition are grouped together.

  • Grouping by Division

The division is splitting into equal parts or groups.

It is the result of “ fair sharing”. In the given example there are 12 chocolates and 3 friends. All 3 should get an equal no. of chocolates. So let's start keeping chocolates in 3 separate places for 3 friends. This process is called division.

At the end of this process, we find that each friend gets 4 chocolates. So 12 divided by 3 gives us 4 or 12 when split into 3 groups has 4 number of items in each group.

  • Grouping by Multiplication

Multiplication is repeated addition of a group with equal items. Like in this example its repeated addition of a group with 3 apples added 3 repeated times which results in a total of 9 apples.

Examples of Questions on Grouping

  • In these types of questions, you are required to analyze the given set of figures, numbers and put them into groups of 2’s, 3’s, 4’s,…

  • Find the number of groups of 2’s, 3’s, 4’s, … that could be formed from the given objects.

Conclusion

On completion of the above grouping exercises, one should be able to group elements one by one in a simple manner. Once the grouping is done, we can easily match the options according to the problem.

We can see how grouping is a base of various mathematical and analytical problem solving which enables us to be equipped for more complex problems in higher standards.

Frequently Asked Questions (FAQs) on Grouping

What is grouping in math?

Grouping is the act or process of combining in groups.

What is a grouping symbol?

Algebraic grouping symbols — parentheses, brackets, braces, radicals, and fraction lines — show where a group starts and ends, and help to establish the order used to apply math operations. Terms inside a grouping symbol have to be operated upon before they can be acted upon by anything outside the grouping symbol.
