Š When we write a number as a sum of place value of its digits, the number is said

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

to be in short form.

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. Name the bird that expands

(b) 35 = 3 tens + 5 ones = 30 + 5 its feathers for dancing when it rains.

35 is the short form. Is this a special bird? Why?
