Sort numbers to 100 small to large
for 1st grade

1st grade : Ordering numbers :
Order numbers from smallest to largest up to 100

In this topic you are asked to look at a mixed up list of numbers and sort them so that the first number is the smallest, the next number is the second smallest and so on. There are 4 numbers in each list, and the numbers can be as small as 1 and as big as 100. In the first question, you have the list :

14, 8, 99, 87

You can see that one of the numbers has only got one digit but the others have two. That number (8) must be the smallest number in that list. Look at the remaining three numbers - one of them starts with a 1 (the 14) but the others start with bigger numbers, so that must be the next smallest number. Two numbers left... one of them starts with an 8 but the other one starts with a 9, so the one starting with an 8 (the 87) must be smaller than the one starting with a 9 (the 99). So the sorted list has to be :

8, 14, 87, 99

In a different question from the topic you are asked to sort the following list :

33, 45, 23, 30

So you do the same thing and look for the smallest number in that list. Look at the first digit of each number and you will see that one of them is a 2, and the others are bigger numbers, so that 23 has to be the smallest number. There are two numbers in the list that start with a 3, so compare their second digit. One of them is a 0 and the other is a 3, so the one with the 0 is next smallest. The biggest number must be the one that starts with a 4, that is 45. So the sorted list is :

23, 30, 33, 45
