English Learning: Numbers (1–100)

Dialogue

Current Situation

Numbers from 1 to 100 are foundational for everyday communication in English. They are used constantly for a wide range of purposes, including:

• Counting: “There are five apples.”
• Age: “She is twenty-three years old.”
• Money: “That costs fifty dollars.”
• Time: “Meet me at seven o’clock.” (Often combined with other time expressions)
• Quantities: “We need a hundred pages.”
• Addresses and Phone Numbers: “My address is seventy-four Oak Street.” (Though phone numbers are often read digit by digit).

Mastering these numbers not only helps in practical situations but also builds confidence in understanding and speaking English in various contexts, from shopping to travel to social interactions. While the basic numbers (one to ten) are simple, numbers from eleven to nineteen and the “tens” (twenty, thirty, etc.) have specific patterns that are crucial to learn.

Key Phrases

• Way off: Far from the correct answer or estimate. Example: “Your guess of ten thousand was way off; the actual number was only one hundred.”
• Twenty-twenty eyesight: Perfect vision. Example: “The pilot had twenty-twenty eyesight, so he could see the runway clearly.”
• Don’t be dramatic: Don’t exaggerate or overreact. Example: “It’s just a small scratch, don’t be dramatic!”
• Snack allocation: The process of distributing or assigning snacks. Example: “The teacher was in charge of snack allocation for the field trip.”
• Bankrupt me: To make someone lose all their money; to cause financial ruin. Often used humorously for something expensive. Example: “Buying that new car will practically bankrupt me.”
• My bad: My mistake, my fault. An informal way to apologize. Example: “Oh, I forgot to send that email. My bad!”
• Fifty-fifty: Having an equal chance; an even split. In the dialogue, used humorously to describe inconsistent memory. Example: “It’s a fifty-fifty chance whether it will rain today.”
• Bargain hunter: Someone who actively looks for products at reduced prices or good deals. Example: “My aunt is a real bargain hunter; she always finds the best deals at sales.”

Grammar Points

1. Cardinal Numbers (1-100)

Cardinal numbers are used for counting and indicating quantity. Here’s how they are generally formed:

• Numbers 1-10: Each has a unique word (one, two, three, four, five, six, seven, eight, nine, ten).
• Numbers 11-19 (the “teens”): These also have unique words, often ending in “-teen” (eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen). Note the irregular spellings of eleven, twelve, thirteen, and fifteen.
• Numbers 20-90 (the “tens”): These are formed by adding “-ty” to the base number (twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety). Note the spelling changes for forty and fifty.
• Numbers 21-99: These are formed by combining the “tens” number with a single digit number, separated by a hyphen.
  • Example: twenty-one, thirty-five, seventy-eight, ninety-nine.
• Number 100: Expressed as one hundred or a hundred.

Key takeaway: Remember the unique words for 1-19, the “-ty” endings for multiples of ten, and the hyphen for numbers between 21 and 99.

2. Using Numbers in Context

Numbers often accompany nouns to indicate quantity. You’ll typically use the plural form of the noun with numbers greater than one.

• Example: “five people“, “two sodas“, “twelve bags of chips”, “forty-seven dollars“.
• When referring to a single item, use the singular noun: “one bag“, “one dollar“.
