A1 COURSE · CLASS 7

Is It Cheap or Expensive?

Thirteen or thirty? One tomato or two tomatoes? How much is or how much are? Three small decisions, and every one of them happens at a supermarket checkout.

EXERCISE 01Speaking

Warm-up

Guess the prices — nobody knows them. Tap a card when you have answered it.

Teacher Alvaro

Numbers are the last thing to become automatic. You can talk about your life in English and still freeze at a price. Today we fix the two hard parts: thirteen against thirty, and one thing against two things.

EXERCISE 04Reading

How to say a price

Short paragraphs with a lot of numbers. Read each one out loud — the numbers are the point.

In England people pay in pounds and pence. One pound has a hundred pence. The symbol for the pound is £, and pence is often written as a small p.

A British twenty-pound note with the pound symbol and the number 20
A twenty-pound note

A price like £2.45 has two parts. The formal way is: two pounds and forty-five pence. Nobody says all of that in a store.

The normal way is short: two pounds forty-five. The words and and pence disappear. In dollars it is the same: $45.78 is forty-five seventy-eight.

A price under one pound has no pounds in it. 89p is eighty-nine pence, or just eighty-nine p. Everybody in England says the letter.

Now the hard part: 13 and 30. The difference is where the voice goes up. ThirTEEN is strong at the end. THIRty is strong at the beginning.

This happens with all of them: fourteen and forty, fifteen and fifty, sixteen and sixty. If you do not hear the price, ask again — even English speakers do.

And one more question, in two shapes. One thing: How much is the chocolate? It's two pounds forty-five. Two or more: How much are the peaches? They're eighty-nine pence.

EXERCISE 05Comprehension

Multiple choice

Click an answer and you get the result right away, with the reason.

Teacher Alvaro
  • How many pence are there in one pound?

    The same as cents in a dollar or a euro.

  • What is the symbol for the pound?

    The other two are the dollar and the euro.

  • What is the formal way to say £2.45?

    Correct, but long. You will hear it in a bank, not in a store.

  • And the normal, short way?

    The words and and pence drop out. That is what you hear at a checkout.

  • How do you say $45.78 the short way?

    Two numbers, no words in the middle. Dollars work exactly like pounds here.

  • How do people say 89p?

    Or eighty-nine pence. Both are normal; the letter is faster.

  • Where is the strong part of the word "thirteen"?

    Thir-TEEN. The voice goes up on the second half.

  • And in "thirty"?

    THIR-ty. Strong first, then quiet. That one difference carries the whole meaning.

  • Which two numbers have the same problem?

    And 14 with 40, 16 with 60, 17 with 70, and so on to 19 and 90.

  • How much ___ the chocolate?

    One thing, so is. The answer starts with It's.

  • How much ___ the peaches?

    More than one, so are, and the answer starts with They're.

  • You do not hear the price. What do you say?

    The text says it: even English speakers ask again with these numbers.

EXERCISE 06Grammar point

One tomato, two tomatoes

Teacher Alvaro

Three rules, and the third one is the only difficult one. Look at the last letter of the word — that letter decides everything.

Almost every plural in English is just + s. The other two rules exist because of sound.
  • Normal: + s — a pineapple → two pineapples · a phone → two phones
  • After s, sh, ch, x or z: + es — a bus → two buses · a dish → two dishes · a pouch → two pouches · a glass → two glasses
  • Consonant + y: remove the y, add ies — a cherry → two cherries · a city → two cities · a baby → two babies
  • Careful: vowel + y is normal — a boy → two boys · a spray → two sprays. Look at the letter before the y.
  • The verb changes too: the tomato is … but the tomatoes are …
  • one phone → two ___

    The normal rule, and it covers most words in English.

  • one bus → two ___

    After an s sound you need the extra e, or you cannot say the word.

  • one dish → two ___

    Same reason as buses: sh, ch, x and z all take es.

  • one city → two ___

    The letter before the y is t, a consonant, so the y becomes ies.

  • one boy → two ___

    Here the letter before the y is o, a vowel — so nothing special happens.

  • one glass → two ___

    It already ends in ss, so it takes es.

  • Which one is WRONG?

    Consonant + y, so country becomes countries.

  • The tomatoes ___ very red today.

    Plural noun, plural verb. The -s on the noun changes the verb too.

EXERCISE 07Grammar point

How much is…? and How much are…?

Teacher Alvaro
The question changes with the thing you are pointing at, and so does the answer.
  • One thing: How much is the milk? — It's one pound.
  • Two or more: How much are the snacks? — They're three dollars.
  • Things you cannot count take is: How much is the bread / the cheese / the water? There is no two breads.
  • The whole answer is short: It's £1. · They're 89p. You do not repeat the word price.
  • To say what you think: I think it's about two pounds. Very useful when you are guessing.
  • How much ___ the wallet?

    One wallet, so is.

  • How much ___ the eggs?

    Six of them in the box, so plural.

  • How much is the bread? — ___ one pound.

    The answer copies the question: is in, it's out.

  • How much are the snacks? — ___ three dollars.

    Plural question, plural answer.

  • How much ___ the cheese?

    You cannot count cheese, so it works like one thing.

  • Which question is WRONG?

    Milk is not countable — there is no two milks — so it never takes are.

  • You are not sure of the price. You say:

    Two small words — I think and about — and the sentence stops promising anything.

  • How much are the tomatoes? — They're ___ .

    More than one pound, so the word pound takes an -s too.

EXERCISE 08Writing practice

Write the plural

Look at the last letter first. Write only the plural word.

Teacher Alvaro

Two of these are traps. Spray and boy end in y, but the letter before the y is a vowel — so they take a normal s.

  • aavocado

  • bsteak

  • cbaby

  • dbus

  • eplane

  • fspray

  • gcountry

  • hdish

  • iglass

  • jcity

  • kpouch

  • lboy

EXERCISE 09Writing practice

Ask the price

Write the whole question with is or are. Example: the milk → How much is the milk?

Teacher Alvaro
  • athe eggs

  • bthe salmon

  • cthe tomatoes

  • dthe bread

  • ethe apples

  • fthe cheese

  • gthe peaches

  • hthe pineapple

EXERCISE 10Speaking

Guess the price

Ask, guess, then say if it is cheap or expensive. Full questions, please — not only the number.

Useful language
How much is / are …?It's … / They're … I think it's about …That's cheap! That's very expensive. Could you repeat, please?
Guess and check. Before you play the video, guess the price of each thing out loud: I think the milk is about one pound. Then watch and see who was closest.

One job for this week. Every time you pay for something, say the price in English in your head. Twice a day, five seconds. Numbers only become automatic with repetition — there is no other way.
