Landing-MThe development of mathematical knowledge and skills contributes to children’s ability to make sense of the world and to solve mathematical situations they encounter in their everyday lives.

Knowledge of basic math concepts and the skill to use math operations to solve mathematical situations are fundamental aspects of school readiness and are predictive of later success in school and in life. The components within this domain address number sense and quantity; number relationships and operations; classification and patterning; measurement, comparison, and ordering; and geometry and spatial sense.

Children with disabilities may demonstrate alternate ways of meeting the goals of mathematics development. For example, a child who is blind may begin to identify braille numbers and a child with a physical disability may identify numerals through use of an eye gaze. Children with disabilities may reach many of these same goals, but at a different pace, with a different degree of accomplishment, and in a different order than their peers. However, the goals for all children are the same, even though the path and the pace toward realizing the goals may be different. Principles of universal design for learning (UDL) offer the least restrictive and most inclusive approach to developing environments and curricula that best serve the mathematics development of all children.


While this domain represents general expectations for mathematics development, each child will reach the individual standards at their own pace and in their own way.
