The Preoperational Stage
Captions available
The idea
Piaget's preoperational stage runs from about two to seven; "pre" means before operations, logical mental actions that can be reversed.
In practice
A seven-year-old seeing that three doubled and seven minus one both make six.
Where people slip
Some sources end the stage at six; either way, concrete operations follow, from about seven.
