Comparing Numbers

We have learned counting numbers. Now we will learn to compare numbers as smaller and bigger numbers.

G1_1_Comp Num_Ice cream

  • Here, we can easily see that number of 10 ice-creams is more than number of 5 ice-creams.
  • So, 5 is smaller number and 10 is bigger number.

Smaller number: The number which comes before another number is the smaller number among them.

Bigger number: The number which comes after another number is the bigger number among them

Example: Compare 13 and 56.

G1_2_Comp Num_Numbers

  • Count the numbers from 1 to 56.
  • From the number table, we can easily see that number 13 comes before 56. So, 13 is the smallest number.
  • 56 is comes after 13, so 56 is biggest number.

We can compare numbers by counting their digits.

One-digit numbers: 1 to 9

Two-digit numbers: 11 to 99

Three-digit numbers: 100

  1. Comparing one-digit numbers
  2. Smaller number: the number comes before

    Bigger number: the number comes before

    G1_4_Comp Num_Numbers

  3. Comparing one-digit numbers and two-digit numbers
  4. One-digit numbers come before two-digits number. So, while comparing one-digit and two-digit numbers;

    Smaller number: One-digit number

    Bigger number: Two-digit number


    G1_5_Comp Num_Monkey
  5. Comparing two-digit numbers
  6. Case 1: From the left side, compare the numbers at first digit.

    Smaller number: The number with the smaller first digit is the smaller number.

    Bigger number: The number with the bigger first digit is the bigger number.


    G1_6_Comp Num_Number block

    First digit numbers are 7 and 4, in which 4 is smaller than 7. So:

    Smaller number: 47

    Bigger number: 78

    Here, 47 comes before 78.

    Case 2: If the first digits are same, then compare the next digits.


    G1_7_Comp Num_Number block

    First digits are same the number 5. So, compare the next digits.

    second digits are 1 and 9, in which 1 is smaller than 9. So:

    Smaller number: 51

    Bigger number: 59

    Here, 51 comes before 59.

  7. Comparing one-digit/two-digit numbers and the number hundred.
  8. All one-digit and two-digit numbers come before the number 100. So:
    Smaller number: One-digit number/ two-digit number.

    Bigger number: Number 100.
