Teens and tens

Teens are numbers like thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, and nineteen. Tens are numbers like thirty, forty, fifty, sixty, seventy, eighty, and ninety.

Also, pay close attention when contrasting teens and tens and listen carefully to understand the difference in pronunciation between 14, 15, 16, etc. and 40, 50, 60, etc.

These are usually the most difficult pairs:
12 - 20  /  13 - 30  /  14 - 40  /  15 - 50
16 - 60  /  17 - 70  /  18 - 80  /  19 - 90

In some statements on Part A, you will have to hear the difference between a teen and a ten in order to answer problems correctly.

When you hear a statement, you must decide whether the number is a teen or a ten. For example, thirteen or thirty.

EXAMPLE:
Statement: Take the number seventeen bus to the shopping center and transfer to the ten.
Restatement: The 17 bus goes to the shopping center.
