This is the second of our easy quizzes on comparing and ordering numbers. Like the previous quiz, it will give you a chance to practice arranging amounts in ascending or descending order, and test whether or not you understand what is meant by the magnitude of a number.
This is one of the simplest things in maths. The first part should be no problem at all – as long as you can count! The second part is really simple too – assuming that you know your times tables that is. Still not sure? Then just play this quiz and you’ll soon be a master of comparing and ordering numbers.
Once you are happy with your performance in these easy quizzes, have a go at our medium ones. As is true of most things, practice makes perfect in maths. Keep testing yourself until you always score 10 out of 10!

-17 + 17 = 0. Whenever you have two identical numbers that differ only in sign - they cancel each other out to give zero
|
72 is the only number greater than zero, so it is the largest

132 ÷ 12 = 11, so 132 is 11 times bigger than 12. That's because there are 11 lots of 12 in 132: 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 132

Remember that going RIGHT means positive numbers increasing. If you move LEFT starting from zero along the number line, the numbers become smaller and smaller negative numbers, not bigger and bigger

'Ascending order' means that the numbers increase in size as you read from left to right
|
Here's how you solve problems like this: add both numbers together THEN divide by two: (-128 + 126) = -2. So, -2 ÷ 2 = -1

32 ÷ 4= 8, so 32 is 8 times bigger than 4. That's because there are 8 lots of 4 in 32: 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 32
|
Here's how you solve problems like this: add both numbers together THEN divide by two: (21 + 75) = 96. So, 96÷ 2 = 48

'Descending order' means that the numbers decrease in size as you read from left to right
|
All the other numbers are negative, so zero is the biggest number. ZERO IS A NUMBER
