 The temperature is -13o. If it rises 39o it will be 26o.

# Negative Numbers (Year 6)

In KS2 Maths children will come to understand negative or minus numbers. In Year Six children should be confident when counting up and down in negative numbers and filling in the gaps in a number sequence. They should also be able to perform addition and subtraction problems with negative numbers and will now be given problems involving 2 and 3 figure negative numbers.

Negative or minus numbers are whole numbers below zero. You may wonder where on earth a negative number would be used. An example of how negative numbers are used would be measuring temperatures. If its colder than the freezing point of water (0oC) we say it is a minus temperature. Addition and subtraction can be tricky with negative numbers. One method that might help is to rearrange the problem. For example:

14 - 8 = 6 so 6 - 14 = -8 It all becomes easier with practise!

Take this quiz to test yours skills at addition and subtraction with negative numbers.

1.
The temperature is -13o. If it rises 39o what is the temperature now?
26o
39o
13o
-26o
39 - 13 = 26 so -13 + 39 = 26
2.
Which of these statements is true?
-1 < -58
-23 < -1
2 < -99
-15 < -20
The symbol < means smaller than
3.
Which is the largest of these numbers?
2
-35
-3
-14
Even the lowest positive number is higher than all the negative numbers
4.
The temperature is -15o. If it falls 8o what is the temperature now?
23o
-7o
-23o
7o
15 + 8 = 23 so -15 - 8 = -23
5.
Which are the missing numbers in this sequence? -33, -35, ___, -39, -41, ___?
-36 and -43
-37 and -42
-37 and -43
-37 and -40
The numbers in this sequence are decreasing by 2 each time
6.
Which of these is the lowest number?
-1
0
-28
-15
Remember that the higher the negative number the less its value
7.
Which of these statements is true?
-33 > -3
-29 > -28
-7 > -17
-44 > -34
The symbol > means greater than
8.
The temperature is -28o. If it rises 13o what is the temperature now?
-41o
-15o
15o
41o
28 - 13 = 15 so -28 + 13 = -15
9.
The temperature is 6o. If it falls 18o what is the temperature now?
24o
-24o
-8o
-12o
18 - 6 = 12 so 6 - 18 = -12
10.
Which is the next number in the following sequence? 10, 5, 0, -5
10
-1
-10
-15
The numbers are decreasing by 5
