Vocabulary - Fractions, decimals and percentages

The vocabulary list provided is a comprehensive collection of terms related to fractions, decimals, and percentages, essential for KS2 mathematics. The list starts with the basics, introducing 'fraction' as a part of a whole, and terms like 'equal' and 'equal parts' that are fundamental in understanding the equal division of a whole. This is followed by terms representing specific fractions such as 'one half', 'two halves', 'one quarter', and so on, illustrating the concept of dividing a whole into several parts. The list also includes fractions such as 'one third', 'two thirds', and 'three thirds', which are crucial in understanding how a whole can be split into three equal parts.

As the list continues, it delves into more complex terms such as 'proportion', 'decimal', and 'decimal fraction', which are important in understanding the relationship between parts and wholes in different numerical forms. The terms 'decimal point' and 'decimal place' are introduced, which are key in representing fractions as decimals. The list also distinguishes between 'proper fraction' and 'improper fraction', and introduces the concept of a 'mixed number', which combines a whole number with a fraction. It further explains the components of a fraction: the 'numerator' and 'denominator', and the concept of 'equivalent' fractions, which are different fractions that represent the same value. The vocabulary set concludes with terms related to converting between fractions, decimals, and percentages, such as 'convert', 'round to the nearest whole number', and 'number of parts per 100', which is the basis for understanding percentages.
