Teaching that matches a child's age, individual strengths and needs, and social and cultural context; it blends child-guided play with intentional adult support to promote learning.

The range of tasks a child can do with help from a more capable person but cannot yet do alone; instruction within this range stretches learning without causing frustration.

The understanding that objects and people continue to exist even when they are out of sight, typically developing in infancy and tested with hiding tasks.

The understanding that quantity, mass, or volume stays the same when appearance changes, such as pouring water into a taller, narrower container; usually lacking in preschoolers.

A young child's tendency to view the world from only their own perspective and to assume others see, feel, and know the same things.

A child's inborn style of reacting to situations and regulating emotions, such as being easygoing, slow to warm, or intense; it shapes how caregivers respond.

Knowledge of how print works, including that text carries meaning, is read left to right and top to bottom, and is made of letters, words, and spaces.

The understanding that the last number spoken when counting a group tells how many objects are in the group, regardless of their arrangement.

The quick, accurate recognition of small quantities without counting, such as instantly seeing three dots on a die; it supports number sense and early addition.
