WHAT?

• Classifying is a process of grouping objects

according to certain characteristics for a

purpose.

• The basic requirement of any system of grouping is that it must be useful

• Classification is the process skill central to

concept formation.




HOW?

• Binary classification system

– The sets of objects is divided into two subsets on the

basis of whether each object has or does not have a

particular property.




BINARY CLASSIFICATION - example




BINARY CLASSIFICATION

1, 2, 3, 5, 646. ¾ of tail coiled

1, 2, 4, 5, 635. Body with circles

1, 3, 4, 5, 624. Striped body

1, 2, 3, 4, 563. Body with scalloped margin

2, 3, 5, 61, 42. Round body

2, 3, 41, 5, 61. Speckled body

NoYesObservable Properties




HOW?

• Multi-stage classification

– Objects are classified in a binary way repeatedly

creating a hierarchy of sets and subsets




Multi-stage classification - Example

Original Set

1, 2, 3, 4, 5, 6

Body Not Speckled

2, 3, 4

Round Body

1

Body Not Round

5, 6

Body Not Striped

3, 4

Striped Body

2

Body WithScalloped Margin

6

Body WithoutScalloped Margin

5

Circle On Body

3

No Circles OnBody

4

Speckled Body

1, 5, 6




HOW?

• Serial ordering

– Ordering objects according to the extent to which

they display a particular property.

– Depending upon the purpose of the classification,objects may be ordered on the basis of size, shape,

color, or a variety of other characteristics.

THOUGHT-STARTER FOR CLASSIFYING

• How is this object like that one?

• How are these objects alike? How are they

different?

• Sort these items according to their properties.

• Put these objects in order and explain the order.

• Group these objects by color (size, texture,smell,

taste, sound, etc)• Classify this set of objects in as many different

ways as you can.

ACTIVITY

• List all classifying activities in the Primary

Science School Curriculum. You need to have

the Curriculum Specification for Year 1 – 6 to

do this.• Select one activity and explain how you are

going to teach the skill of classification to your

students.
