We describe what the numerator of a fraction is and also offer examples of just how the concept could be taught in Key Stage 2, and also explaining fractions equivalence and the partnership in between the numerator and denominator.

You are watching: A fraction with a numerator of 1

The numerator is the top number of a fraction. So in the fractivity 3/8 the numerator is 3. In the fractivity 1/9 the numerator is 1.If a portion has 1 as its numerator, it is called a unit fraction.
Children must uncover one half, one quarter and also 3 quarters of shapes in Year 2. It is not until Year 3 that they begin actually having to use fraction notation (that is, looking at the diagram below and also composing '3/6' to express what they are seeing). At this allude they will be introduced to the truth that the top number is the numerator and the bottom number is the denominator.   ## Start your boy on a discovering programme!

It is valuable for them to view diagrams so that they are conscious that the numerator is the variety of components shaded (for example, in the fraction over, 3 components out of 6).
In Years 3 and 4, children learn around equivalence. They will look at diagrams prefer the complying with fractions equivalence wall: and also begin to understand also how fractions have the right to be the same, even if they are break-up up right into different numbers of components, which give them various denominators.They likewise must look at the relationship between the numerator and also denominator in tantamount fractions; for example, in the diagram listed below, they might alert that 2 is a 3rd of 6 and 4 is a third of 12. In Years 4, 5 and also 6 children have to relate fractions to their decimal equivalents. To understand this, it is advantageous for them to understand also that decimals resolve whole numbers being separation into one hundred equal parts, so a decimal number have the right to be compared to a portion with 100 as the denominator. The number that occurs after the decimal point in a decimal number then forms the numerator of an tantamount fractivity, for example: 0.41 is 41/100. Children then need to have the ability to simplify fractions by splitting the numerator and denominator by the exact same number.They may additionally be given a list of fractions via various denominators and asked to convert them so that they all have the exact same denominator. This entails either multiplying or dividing both the numerator and also denominator by the exact same number.
