Most of the things we know can be separated into groups, which have common characteristics that have been identified.
As an example, let us consider the following collection of animals.
The animals in this figure can be grouped in various ways. A way of separating these animals into two groups is given below.
A common characteristic of the animals in this group is that they each have four feet.
Therefore, this group can benamed as "Four-footed animals inthis collection of animals".
A common characteristic of the animals in this group is that they all can fly. Therefore this group can be named as "Birds in this collection of animals".
Another common characteristic is that they each have only two feet. Therefore, this group can also be named as "Two-footed animals in this collection of animals".
These animals can also be separated into three groups named Herbivores, Carnivores and Omnivores based on what they eat.
(1) Separate the collection of items in each of the figures given below into two groups according to the given characteristics and write them down.
(2) Separate the following items into three groups based on their common characteristics and write down their names. Write a suitable name for each group.
(3) Two of the common characteristics that were used to separate the following numbers into four groups are given. Identify a common characteristic for each of the other two groups. Give a suitable name to each group and then separate all the given numbers appropriately into the four groups and write them down.
