Numerator

In a fraction, the numerator is the top number that represents the number of equal parts being considered. It is the part of the fraction that tells us how many parts of the whole we are talking about. For example, in the fraction 3/5, the numerator is 3. This means that we are talking about 3 out of the 5 equal parts of the whole.

The numerator is an essential part of a fraction and is always written above the fraction line (or the "vinculum"). It is important to understand the numerator when working with fractions, as it helps us understand the value of the fraction and how much of the whole is being considered.

Understanding the numerator is fundamental for young learners as they begin to explore fractions and their relationship to whole numbers. It is also important for understanding concepts such as equivalent fractions, comparing fractions, and adding or subtracting fractions.

The resources above cover the following skills:

Counting and Cardinality

Know number names and the count sequence.

Count to 100 by ones and by tens. [K-CC1]

Count forward beginning from a given number within the known sequence (instead of having to begin at 1). [K-CC2]

Count to tell the number of objects.

Understand the relationship between numbers and quantities; connect counting to cardinality. [K-CC4]

Understand that each successive number name refers to a quantity that is one larger. [K-CC4c]

Compare numbers.

Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. (Include groups with up to ten objects.) [K-CC6]

Operations and Algebraic Thinking

Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations. (Drawings need not show details, but should show the mathematics in the problem. This applies wherever drawings are mentioned in the Standards.) [K-OA1]

Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem. [K-OA2]

Fluently add and subtract within 5. [K-OA5]
