HOW?
• Multi-stage classification
– Objects are classified in a binary way repeatedly
creating a hierarchy of sets and subsets

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.
