In Year 5, the third year in KS2, children will be exposed to negative, or minus, numbers in Maths. They should be able to count up and down in negative numbers, possibly with the aid of number lines, which will enable them to fill in gaps in a number sequence. They should also be able to perform some basic addition and subtraction problems involving negative numbers.
Negative numbers are shown with a minus sign directly before the number. For instance 10. Negative numbers are used for measuring temperature and also to denote a loss, such as a debt. On negative number lines, the sequence of numbers goes the opposite way to that on positive number lines. For example, in this sequence: 5, 6, 7, 8... etc.
See how much you know about negative, or minus, numbers by playing this quiz.














Negative numbers are the opposite of positive numbers therefore 1 is larger than all the other negative numbers

Remember, the higher the negative number the lower its value


Negative numbers go down in the same sequence that positive numbers go up in

The symbol < means less than. The smaller part of the symbol is next to the smallest number


The symbol > means greater than. The larger part of the symbol is next to the largest number

This sequence is going down by 1 each time


5  2= 7

8 + 3 = 5


One way to work this out is to split the 8 into 4 and 4 like this:
4  4 = 0 0  4  = 4 
3 + 12 is the same as 12  3
