Even Numbers & Odd Numbers  By Aashish Gupta Sir              Class 1 & 2          Even Numbers Numbers which are exactly divisible by 2 , are called Even Numbers.  Even numbers have 0, 2, 4, 6 or 8 at their ONE'S place. Example -   1 8   , 4 0 , 5 4 , 7 2 , 5 6 etc. Odd Numbers Numbers which are not  exactly divisible by 2 , are called Odd  Numbers.  Odd numbers have 1, 3, 5, 7 or 9 at their ONE'S place. Example -  1 9 , 2 7 , 3 3 , 4 5 ,  7 1 etc. How to check a numbers for Even or Odd Example 1. Check whether 57 is even or odd. Step 1 : One's digit in 57 is 7. Step 2 : We know that  one's digit in odd number should be 1,3,5,7 or 9. Step 3 : Here one's digit is 7. So we can say that 57 is an odd number. Example 2. Check whether 56 is even or odd. Step 1 : One's digit in 56 is 6. Step 2 : We know that  one's digit in even number should be 0,2,4,6 or 8. Step 3 : Here one's digit is 6.  So we can say that 56

Bigger Number & Smaller Number By Aashish Gupta Sir                Class 1 &  2           Bigger Number How to Find Bigger Number in 2- digit numbers Example 1 :  Which is Bigger  - 34  or 67 Step 1 :  Put given numbers in a Place Value Chart                Tens      Ones            3              4            6              7     Step 2 : Check Tens digit of both the numbers. Number having bigger Tens digit is bigger. Step 3 :Here Tens digit are  3 &  6. We know 6 is bigger than 3. So 67 is bigger than 34. Example 2 :  Which is Bigger  33 or 36 Step 1 :Put given numbers in a Place Value Chart         Tens      Ones            3              3            3              6     Step 2 : Check Tens digit of both the numbers. Number having bigger Tens digit is bigger. Step 3 :Here Tens digit are  3  &  3. Both have same Tens digit 3. So we proceed to next step. Step 4 : Since Tens digits are same, so we now compare Ones digits. Here ones digit are 3

Place Value & Face Value By Aashish Gupta Sir               Class   4             Places and Place Values of   5 -Digit Numbers There are five places in a 5 -Digit Number    Ten    Thousands  Hundreds  Tens  Ones Thousands  T Th           Th               H              T        O ×10,000    ×1000          ×100        ×10      ×1     9                 5                 7             8         6 (9×10000)+( 5×1000)+(7×100)+(8×10)+ (6×1) Here in 5-digit no. there are five places -   Ones , Tens , Hundreds ,  Thousands and  Ten Thousands. Value at a Place Value of digit at Ones place is 1 times. Value of digit at Tens Place is 10 times. Value of digit at  Hundreds Place is 100 times. Value of digit at  Thousands Place is 1000 times. Value of digit at  Ten Thousands Place is 10,000 times. How to find Place Value of Digit at Ones Place Digit at Ones place  is multiplied by 1 to get its place Value .  Here in this case digit at ones place is 6 ,  so we multiply 6 by 1 to

Place value &  Face Value By Aashish Gupta Sir                 Class   3            Places and Place Values of 4 -Digit Numbers There are four places in a 4 -Digit Number   Thousands     Hundreds      Tens     Ones        Th                     H                  T            O     ×1000               ×100              ×10        ×1         5                        7                   8           6 =( 5× 1000)  +   (7 ×100) +    (8× 10) + ( 6× 1) Here in 4-digit no. there are four places -   Ones , Tens , Hundreds and Thousands . Value of digit at Ones place is 1 times. Value of digit at Tens Place is 10 times. Value of digit at  Hundreds Place is 100 times. Value of digit at  Thousands Place is 1000 times. How to find Place Value of Digit at Ones Place Digit at Ones place  is multiplied by 1 to get its place Value .  Here in this case digit at ones place is 6 ,  so we multiply 6 by 1 to get place value of 6  i.e. 6×1 = 6.
