Which mathematical skill is NOT usually associated with kindergarten?

In kindergarten, students typically focus on foundational mathematical concepts that will serve as a basis for future learning. One of the primary skills emphasized at this age is counting, which includes counting to 100. Recognizing shapes is another key skill, helping young learners identify and describe basic geometric figures. Basic addition also falls within the scope of kindergarten math, as it introduces young children to the idea of combining groups and understanding the concept of sums.

Understanding decimals, however, is not generally a skill emphasized in kindergarten. At this developmental stage, children are still grappling with whole numbers and basic arithmetic. Decimals are typically introduced at a much later stage in education, often in elementary school when students have a solid grasp of whole-number operations. Therefore, identifying decimals as a concept for kindergarten does not align with the grade-level expectations.
