Stage | Characterized by |
| Sensori-motor (Birth - 2 years) | Differentiates self from objects Recognizes self as agent of action and begins to act intentionally: e.g. pulls a string to set mobile in motion or shakes a rattle to make a noise Achieves object permanence: realizes that things continue to exist even when no longer present to the sense (place Bishop Berkely) |
| Pre-operational (2 - 7 years) | Learns to use language and to represent objects by images and words Thinking is still egocentric: has difficulty taking the viewpoint of others Classifies objects by a sinle feature: e.g. groups together all the red blocks regardless of shape or all the square blocks regardless of color |
| Concrete operational (7 - 11 years) | Can think logically about objects and events Achieves conservation of number (age 6), mass (age 7), and weight (age 9) |
| Formal operational (11 years and up) | Can think logically about abstract propositions and test hypotheses systematically Becomes concerned with the hypothetical, the future, and idealogical problems |
This is misleading sort of – math is a skill that is learned in the operational stage along with inductive logic.
