Grade 2 Math Place Value & Face Value
Place Value and Face Value
What is Place Value?
The value of a digit in a
number based on its position in the number is called its place value.
Example:
Place value of 6 in 360 = 6 tens = 60.
Understand place Value (Up to 3
digits):
(i) Know the place names:
Look at the below table and
read the names of three places for 3 digits in a number.
|
3
|
1
|
5
|
|
Hundreds Place
|
Tens Place
|
Ones Place
|
So, The place value name
of 1st digit from the right is Ones place.
The place value name of 2nd
digit from the right is Tens place.
The place value name of 3rd
digit from the right is Hundreds place.
(ii) Calculate Place Value:
Ones place digit value = 1×Ones
place digit.
Tens place digit value = 10×Tens
place digit.
Hundreds place digit value =
100×Hundreds place digit.
Suppose a number is 763.
For 763,
Ones place digit = 3
Tens Place digit = 6
Hundreds Place digit = 7
So,
Ones place digit value = 1×3
= 3.
Tens place digit value = 10×6
= 60.
Hundreds place digit value =
100×7 = 700.
What is Face Value?
Face value is the original value
of a digit as it is mentioned in a number. The actual digit value = its face
value, not its place value.
Suppose a number is 387.
Face value of 8 in 387 is 8.
1. Calculate the place
value of the following number's digits.
(a) 351
(b) 306
(c) 279
(d) 666
(e) 64
Solution:
(a) 351
Place value of Ones place digit
= 1×1 = 1.
Place value of Tens place
digit = 10×5 = 50.
Place value of Hundreds place
digit = 100×3 = 300.
(b) 306
Place value of Ones place digit
= 1×6 = 6.
Place value of Tens place
digit = 10×0 = 0
Place value of Hundreds place
digit = 100×3 = 300.
(c) 279
Place value of Ones place digit
= 1×9 = 9.
Place value of Tens place
digit = 10×7 = 70.
Place value of Hundreds place
digit = 100×2 = 200
(d) 666
Place value of Ones place digit
= 1×6 = 6.
Place value of Tens place
digit = 10×6 = 60.
Place value of Hundreds place
digit = 100×6 = 600.
(e) 64
Place value of Ones place digit
= 1×6 = 6.
Place value of Tens place
digit = 10×6 = 60.
2. Calculate the place
value of the digits in 636, 446, 908 and 999.
Solution:
636 = 6 hundreds 3 tens and 6
ones = 600 + 30 + 6
So, In the number 636, Place
value of 6, 3 and 6 = 600, 30 and 6.
446 = 4 hundreds 4 tens and 6
ones = 400 + 40 + 6
So, In the number 446, Place
value of 4, 4 and 6 = 400, 40 and 6.
908 = 9 hundreds 0 tens and 8
ones = 900 + 0 + 8
So, In the number 908, Place
value of 9, 0 and 8 = 900, 0 and 8.
999 = 9 hundreds 9 tens and 9
ones = 900 + 90 + 9
So, In the number 999, Place
value of 9, 9 and 9 = 900, 90 and 9.
3. What is the face value
of 6 in 363?
Answer: 6
4. What is the face
value of 3 in 321?
Answer: 3
