kümneselise

Kümneselise is a term used in Estonian mathematics education to refer to a decimal number, specifically one that is being represented or discussed in the context of tens. This concept typically arises when introducing place value and the decimal system to young learners. The focus is on the digit that occupies the tens place within a larger number. For example, in the number 37, the kümneselise would be 3, representing three tens.

The term is often used in elementary school to help students grasp the concept of how numbers are constructed and how digits contribute different values based on their position. When a child is asked to identify the "kümneselise" in a number, they are being prompted to isolate and understand the value of the tens digit. This understanding is foundational for performing arithmetic operations with larger numbers and for comprehending fractions and percentages, which are also based on the decimal system. The term emphasizes the relationship between a digit and its corresponding place value, making the abstract concept of numbers more concrete for beginners.
