Which of the following is considered one of the earliest numeracy skills in young children?

Counting is regarded as one of the earliest numeracy skills in young children because it serves as a foundational mathematical concept that helps them understand the quantity and value of numbers. Young children often begin by learning to count in sequence, which lays the groundwork for understanding more complex mathematical operations such as addition and subtraction. It also helps them develop number sense, an essential component that allows them to recognize and manipulate numbers in various contexts.

While measurement, geometry, and spatial awareness are important mathematical concepts in early childhood education, they typically build on the foundational skill of counting. Measurement involves comparing sizes or amounts, geometry relates to shapes and spatial relationships, and spatial awareness involves understanding how objects relate to each other in space. These skills usually develop after children have gained familiarity with counting and basic numerical concepts.
