1. KNOWING OUR NUMBERS

•  Number: A number is a mathematical object used to count and measure.1,2,3…….etc.

Comparing numbers:

• We can compare the numbers by counting the digits in the numbers.

• Now Compare   5432 and 4678…

5432 is greater as the digits at the ten thousand place in 5432 is greater than that in  4678.

Order of numbers:

• Ascending Order: –

arrange the numbers from smallest to the greatest; this order is called Ascending order.

 Ex:- 23, 44, 65, 79, 100

• Descending Order: –

arrange the numbers from greatest to the smallest, this order is called Ascending order.

 Ex:- 100,79, 65, 33, 23

Formations of numbers

• Form the largest and smallest possible numbers using the digits 3, 2, 4, 1 without repetition

• Largest number formed by arranging the given digits in descending order _ 4321. 

• Smallest number formed by arranging the given digits in ascending order _ 1234.

• Greatest two-digit number is 99.

• Greatest three-digit number is 999.

• Greatest four-digit number is 9999.

 Place value

• Place value is the positional notation, which defines the position of a digit.

  Ex:- 3458     

8 is one place, 5 is tens place, 4 is hundreds place and 3 is thousands place.

Expanded form

• It refers to expand the numbers to see the value of each digit.

Ex :- 3458 = 3000 + 400 + 50 + 8

                    = 3×1000 + 4×100 + 5×10 + 8×1

• Note:-

        1 hundred = 10 tens

       1 thousand = 10 hundreds

      1 lakh = 100 thousands = 1000 hundreds
