  The temperature is 4o. If it falls 8o it will become -4o.

# Negative Numbers (Year 5)

In Year 5, the third year of KS2 Maths, you'll explore special numbers called negatives. Imagine counting backwards on a number line! With these minus numbers, like -10, you can fill in gaps and solve tricky problems. It's like a cool maths adventure!

Negative numbers have a special sign (it's a minus!). They're used for things like measuring temperature and showing when something is lost, like owing money. On number lines, they go the other way - like a secret code: -5, -6, -7, -8... How cool is that?

1.
The temperature is -5o. If it falls 2o what is the temperature now?
7o
-3o
-7o
3o
-5 - 2= -7
2.
Which is the next number in the following sequence? 0, -1, -2, -3, -4
5
-4
-5
-6
Negative numbers go down in the same sequence that positive numbers go up in
3.
The temperature is 4o. If it falls 8o what is the temperature now?
0o
-3o
-4o
-8o
One way to work this out is to split the 8 into 4 and 4 like this:
4 - 4 = 0
0 - 4 - = -4
4.
Which of these statements is true?
-1 < -4
-2 < -6
2 < -2
-5 < -3
The symbol < means less than. The smaller part of the symbol is next to the smallest number
5.
Which of these is the largest number?
-1
-2
-3
-4
Negative numbers are the opposite of positive numbers therefore -1 is larger than all the other negative numbers
6.
Which of these is the smallest number?
0
-1
-3
-5
Remember, the higher the negative number the lower its value
7.
Which are the missing numbers -1, -2, __, -4, -5, __?
-3 and -6
3 and 6
-3 and 6
3 and -6
This sequence is going down by 1 each time
8.
The temperature is -3o. If it rises 12o what is the temperature now?
9o
-9o
-15o
3o
-3 + 12 is the same as 12 - 3
9.
The temperature is -8o. If it rises 3o what is the temperature now?
-11o
11o
-5o
5o
-8 + 3 = -5
10.
Which of these statements is true?
-3 > 3
-1 > -7
-5 > -2
-4 > -3
The symbol > means greater than. The larger part of the symbol is next to the largest number
