Biggest number: 50 - 100
for 1st grade

1st grade : Comparing numbers :
Choose the biggest number from 50 to 100

In this topic you are asked to look at a group of numbers and decide which number is the biggest. There are 6 numbers in each group, and each number is between 50 and 100. In the first question, you have the following group of numbers :

66, 71, 79, 86, 77, 69

Start by looking at the first digit of each number - they are 6, 7, 7, 8, 7 and 6. So, if numbers have the same number of digits, then the number with the biggest first digit is the biggest number. We can see that we have a number with an 8 as the first digit, the 86, and the other numbers have smaller first digits so that has to be the biggest number in the group. So in this group the biggest number has to be :

Biggest number = 86

In another question from the topic you are asked to find the biggest number from the following group of numbers :

99, 56, 80, 60, 96, 77

So we use the same technique as last time and look at the first digit of each number in that list. You will see that one of them is a 5, and the others are all bigger numbers, so that 56 cannot be the biggest number.

There are two numbers in the list that start with a 9, so compare their second digit. They are 9 and 6. We know that 9 is bigger than 6 so the biggest number in the list has to be :

Biggest number = 99
