**This page is to help parents understand terms and how they can help.**

The guidance in interpreting the criteria is to help teachers and parents understand the expectation of the national standard at each key stage so that a partnership is established in helping the child progress to their potential. Some of the terms used in the standards are technical and these are explained below.

**Integer** – An integer is any whole number such as 1, 23, 54. The word integer is used a lot in mathematics and computer science and so it is a good word to use whenever you mean a whole number. Children will then pick this up as a natural part of their vocabulary.

**Numeral** – A numeral is a number written as a number eg 1, 5, 9

**Place value** – Place value is a way of using the same numerals to represent different numbers. 5 by itself means five objects. 50 means fifty objects. In an integer, the right most digit is the number represented by the numeral. Where two numerals are written as a pair eg 51, the left numeral is ten times the value of the numeral in that place and so in the case of fifty one, the 5 means fifty. The right digit is one and so writing the number 51 means fifty plus one or fifty one. Each place shifted to the left multiplies the numeral by another 10. This means 100 is one hundred and 1000 is one thousand and 20000 is twenty thousand. For decimal numbers, the digit to the right of the decimal number is tenths and two places to the right, hundredths. Place value determines the size of numbers from the numerals and their positions in relation to each other.
