Let us think about the number 78. It has two digits 7 and 8. Tens Ones

In the number, the digit 8 is in the ones place, so its place 7 8

value is 8 ones or 8. The digit 7 is in the tens place, so its Place value
8 ones = 8
place value is 7 tens or 70. 7 tens = 70

The place value of a digit depends upon its
position in a given number. The face value of Challenge Question

a digit is the value of the digit itself. Aman claims, “When you add 60 +
7, that is 6 tens and 7 ones.” Ayesha
ExPANdEd foRM ANd ShoRT foRM argues, “No, it is 7 tens and 6 ones.”
Who is correct?

Š When we write a number as a sum of the
place values of its digits, the number is said to be in expanded form.

Š When we write a number using digits, the number is said 24 is the short form
to be in short form. of 2 tens + 4 ones

65 = 6 tens + 5 ones or 60 + 5 is the expanded form of 65.

65 is the short form of the number sixty-five.
Similarly,

(a) 68 = 6 tens + 8 ones = 60 + 8 www
68 is the short form. MAths connect

(b) 35 = 3 tens + 5 ones = 30 + 5 Name the bird that expands Cross-Curricular Learning

35 is the short form. its feathers and dances when it rains. Is
this a special bird? Why?

1. Write the place value of the highlighted digit in each number.

(a) 52 = ______ (b) 84 = ______ (c) 70 = ______ (d) 15 = ______

2. Write these numbers in the expanded form. One has been done for you.
40
7
(a) 47 = ___ + ___ (b) 73 = ___ + ___ (c) 34 = ___ + ___ (d) 75 = ___ + ___
(e) 90 = ___ + ___ (f) 79 = ___ + ___ (g) 94 = ___ + ___ (h) 38 = ___ + ___

3. Write these numbers in the short form. One has been done for you.
(a) 3 tens + 4 ones = 34 (b) 6 tens + 9 ones =

(c) 6 tens + 6 ones = (d) 5 tens + 5 ones =

(e) 9 tens + 8 ones = (f) 8 tens + 1 one =
