## What is the theory of conservation of number?

The conservation of number principle asserts that the number of solutions of any determinate algebraic problem in any number of parameters under variation of the parameters is invariant in such a manner that no solutions become infinite.

How did Piaget test conservation?

Piaget described several conservation experiments. For example, in his conservation of mass experiment, a bit of clay (which Piaget called plasticene) was rolled into a ball. A second ball of clay the same size is shown to the child, who agreed they were equal.

### In which of Piaget’s stages does a child understand conservation?

The concrete operational phase centers around three elements : Conservation and reversibility: Conservation the understanding that objects can change in size, volume, or appearance but essentially remain the same.

What does conservation of length mean?

rigid body remains invariant under changes. of position and (2) the length of a whole. remains invariant whenever each of its. parts remains the same length.

#### What is conservation length?

This refers to the ability of a child to recognize the constancy of matter over given perceptual transformations. Length conservation, in particular, is the recognition that the following transformations do not change the length of the objects involved (Fig. 1).

What does lack of conservation mean?

Lack of Conservation – realising that something can have the same properties even if it appears differently.

## What is concept of conservation?

1 : a careful preservation and protection of something especially : planned management of a natural resource to prevent exploitation, destruction, or neglect water conservation wildlife conservation. 2 : the preservation of a physical quantity during transformations or reactions.

What is conservation capacity?

Capacity for Conservation is an aid to self-led organisational development. It aims to support you to strengthen your organisation to achieve – and sustain – your conservation and organisational development goals.
