 LESSON -3   (NUMBERS FROM 11-20 )                                                   29.04.2020



LEARNING OUTCOME

• define the  place value of a number
• write the place value of the numbers 10 to 20.
• tell what is a digit .

 Dear children

Now lets understand what is a digit.  

A digit is a part of a number.It can be any number from 0 to 9 and is a single digit number.For
example 4 is a single digit number. The digits 0,1,2,3,4,5,6,7,8 and 9 are used to form different numbers.

Number 12 consists of two digits :1 and 2
Number 18  also consists of two digits :1 and 8
 
 Now quickly tell me how many digits are there in number 14?

Absolutely Correct !! It has 2 digits (1 and 4 )

What is a place value?

The place value of a digit is the value of the digit because of its position or place in a number,whether it is in ones or tens place.
When a number is a single digit number, the number is in the ones place

Look at the digits 1 and 4.When we use 1 and 4 to write the number 14, we need two places.We write '4'  in the ones place and '1' in the tens place.

So the place value of 4 is 4 ones or 4
The place value of 1 is 1 ten or 10

So if I expand number 14 it will be-
14= 1 ten + 4 ones or 10 + 4

Now lets try number 16

So the place value of 6 is 6 ones or 6
The place value of 1 is 1 ten or 10

So if I expand number 16 it will be- 
16=1 ten +6 ones or 10 + 6
