1. Piaget's Concrete Operations
concrete operational stage of development can
be defined as the stage of cognitive development in
which a child is capable of performing a variety of
mental operations and thoughts
using concrete concepts

3. Conservation
Conservation is the understanding that something stays the same in
quantity even though its appearance changes. To be more technical
conservation is the ability to understand that redistributing
material does not affect its mass, number, volume or length.

7. Decentration
Decentration involves the ability to pay attention to multiple
attributes of an object or situation rather than being locked
into attending to only a single attribute. When children are
asked to compare the volume of Apples, it is their ability to
decentrate that enables them to flexibly consider both the
height and the width of the Apples in arriving at their
decision. Through the development of decentration skills,
older children start to be able to pay attention to more than
one thing at at time.

8. Reversibility
 Reversibility takes conservation one step further. Children capable of conservation
appreciate that an object's quality is not altered simply by transforming how that object
appears. Children capable of reversibility appreciate that if an object's quality is altered
through some true subtraction or addition, the object's original quality can be restored by
reversing the alteration. This capability is enabled in large part through the maturation of
children's memory so as to enable their retention of awareness of a series of events and
their ability to run backwards through those remembered events so as to see how
something transformed could be restored to its initial state. An example of this is being
able to reverse the order of relationships between mental categories. For example, a child
might be able to recognize that his or her dog is a Labrador, that a Labrador is a dog, and
that a dog is an animal.

10. Classification
 Beyond conservation, Piaget also believed that children in middle childhood master
hierarchical classification; the ability to simultaneously sort things into general and more
specific groups, using different types of comparisons. Most children develop hierarchical
classification ability between the ages of 7 and 10. The ability to perform hierarchical
classification is very useful to children in school, as they begin to understand and
appreciate science and social studies concepts which involve making just such
comparisons, for instance, sorting living creatures into different groups based on
whether they are animals or plants, etc.

12. Seriation
 The cognitive operation of seriation involves the ability to mentally arrange
items along a quantifiable dimension, such as height or weight.
