slide1. KNOWING OUR NUMBERS Place value
Face value
Ascending and Descending order
Greatest and Smallest numbers<br>
slide2. KNOWING OUR NUMBERS Place value : Place value of a digit in a number depends upon the position of the or the place it occupies in the place value chart.
For example - place value of 5 in 4578 is 500 as 5 is in the hundreds place so place value of 5 in 4578 is 5 X 100 = 500.
Face value : Face value of any digit in a number is the digit itself , it independent of its position in the number. It is always the digit itself.
For example – Face value of 3 in 3456 is 3 and also face value of 3 in 5637 is 3.<br>
slide3. KNOWING OUR NUMBERS 1. Write the place value and the face value of the underlined digits in the following numerals :
a. 328740531
b. 317432
c. 81273
d. 4031652<br>

slide5. KNOWING OUR NUMBERS ASCENDING AND DESCENDING ORDER
Ascending order : - Ascending order means arrangement from the smallest to the greatest.
Descending order :- Descending order means arrangement from the greatest to the smallest.<br>
slide6. KNOWING OUR NUMBERS 1. Arrange the following numbers in ascending order :
a. 8287642; 8278642; 8287462; 8287362;
b. 910000003; 9100003; 9103; 910003im<br>
slide7. KNOWING OUR NUMBERS 2. Arrange the following numbers in descending order :
a. 330033033; 333300033; 330033330; 330003033
b. 321397642; 3412976; 9317624; 321679<br>
slide8. KNOWING OUR NUMBERS Greatest and Smallest Numbers –
To form the greatest number from a given set of digits , we write the digits in the descending order.
To form the smallest number from a given set of digits , we write the digits in the ascending order, however we never start a number with the digit 0.<br>
slide9. KNOWING OUR NUMBERS 3. Form the smallest and the greatest 4 – digit numbers using the digits given below ( Without repetition ) :
a. 2, 0, 1, 3
b. 6, 4, 9, 3
c. 3,2,1,6<br>
slide10. KNOWING OUR NUMBERS 4. Form the smallest and the greatest 5 – digit numbers using the digits given below (repetition of digits is allowed and all the digits should used ) :
a. 6, 3, 8
9, 0, 4
3, 1, 4
7, 5, 2<br>
slide11. KNOWING OUR NUMBERS 5. Write the greatest 9 – digit number using four different digits.<br>
slide12. KNOWING OUR NUMBERS 6. Make the greatest and the smallest 4 – digit numbers using any four different digits with the condition given below.
a. 8 is always in the ones place
b. 3 is always in the tens place
c. 4 is always in the thousand place
d. 6 is always in the thousand place<br>
