Which of the following is nota pre-number concept ?

Correct option is D

Pre-number concepts are fundamental skills that children develop before they begin to learn about numbers. These concepts help children understand and manipulate quantities, spatial relationships, and patterns. Approximation is not considered a pre-number concept because it involves estimating quantities rather than understanding exact values.

Pre-number concepts are foundational ideas that children develop before formal counting begins. These include skills like matching, classifying, seriating, and approximation, which help them understand mathematical relationships.

• Approximation involves estimating quantities, which is a part of pre-number concepts.
• Seriating is arranging objects in order, like by size, and is a core pre-number concept.
• Matching is pairing similar items, also a pre-number concept.
• Hierarchical inclusion, however, is related to understanding that a number includes all previous numbers (e.g., 5 includes 4, 3, 2, 1). This concept typically comes after a child begins to understand formal number operations.
