In KS2 Maths, you'll learn about negative or minus numbers. In Year Six, it's important to feel comfortable counting up and down in negative numbers and filling in missing numbers in a sequence. You'll also tackle addition and subtraction problems with 2 and 3 figure negative numbers.
Negative numbers are whole numbers below zero. Think about temperatures – if it's colder than 0oC, we say it's a minus temperature. Adding and subtracting with negatives can be tricky, but one trick is to rearrange the problem. For example:
14 - 8 = 6, so 6 - 14 = -8. It gets easier with practice!
Now, have some fun and test your skills with addition and subtraction of negative numbers in this quiz.
