  1. Introduction.

Greeting and Aim


The bell has rung

The lesson has begun

The teacher’s in the class

And she’s glad to see us

It’s time to study

It’s time to work hard

We want to know English

And that is our task.


Good morning, guys.

Today we are going to have quite an unusual lesson. We are going to talk about Math. I’m not going to teach you Math, I’m not so good at it to teach you. But I can teach you how to talk about it.

Also we will practice saying and understanding big numbers a lot of pupils have problems with.

Warming-up

Foreigners often confuse such numbers as sixty and sixteen. Repeat after me paying attention to the difference

Thirty-thirteen, nineteen-ninety, seventeen-seventy, forty-fourteen, fifty – fifteen,

Eighteen- eighty

  1. Main Part.
  1. First of all, let’s revise the spelling of the following numbers

Now big numbers. You can see ones drawn on the board. Don’t forget about “and” (9 and 99)

9 – 99 – 999 – 9,999 – 99,999 – 999,999 – 9,999,999

• Choose nine of the big numbers and write them in a Bingo! grid :

 

 

 

 

 

 

 

 

 

 

• I read the numbers clearly in a random order, pausing between each number to give students time to find it on their Bingo! grid – but don’t make it too easy! Mark each number with a ‘x’ as you call it out.

 • Students listen and play Bingo! The student who calls Bingo! has to read out each of their numbers for you to check.

  1. Now let’s look at the next symbols and terms

+ add, plus         5+7=        ; 12+19=    ; 123+654=

-subtract, minus    22-3=     ; 33-9=    ; 38- 26=  

= equals, is

*multiply, times   9*8=     ;   12*13=    ; 36*2=

: divide by           42:2=     ; 121:11=     ; 81:9=

 

  1. Brainstorming.

Before we start solving the tasks answer the question: Do we need Math in our everyday life? – Incredibly! The laws of Math govern everything around us. So, let’s brainstorm some reasons why Math is a powerful and incredibly useful tool.

 

What ideas do you have?

  1. It helps you with your finances
  2. It helps you tell time
  3. Makes you a better cook ( you’d better know how much of something you need for many people)
  4. It’s used in practically every career in some way
  5. It’s good for your brain ( as sport for your body- builds up muscles, math does the same for your brains)
  6. It trains our ability to think analytically and solve problems
  7. Nobody can fool you around when you’re shopping
  8. Can make you more popular. Let’s say you go to dinner with your friends and need to split the bill. And it’s really cool when you can divide a check in your mind to know how much each person needs to pay. For me a person who can do mental math quickly is COOL!
  9. Math is the universal language: 2+2=4 in every single place on planet Earth

 

  1. Listening and solving the tasks.

It is time to see how good you are at math and logical thinking.

 

Q.1 If there are 4 apples and you take away 3, how many do you have?

Q.2 Mr. Smith has four daughters. Each of them has a brother.

       How many children does Mr. Smith have?

Q.3 A farmer has 17 sheep and all but 9 died.

       How many are left alive?

Q.4 When my father was 31, I was 8. Now he is twice as old as me. How old   

       am I?

Q.5 Joe is turning 17 this year, yet, he turned 16 only yesterday. How is this

       possible?

Q.6 Which three numbers have the same answer whether they are added or

       multiplied?

Q.7 A book costs 1$ plus half its price. How much does it cost?

Q.8 If cats kill 7 rats in 7 minutes. How many cats would be needed to kill one hundred rats in 50 minutes?

Q.9 A is a father of B. But B is not the son of A. How is that possible?

Q.10 If it took eight men ten hours to build a wall, how long would it take four men to build it?

 

 

6. Pair work.

Now we are going to apply your knowledge in practice. You have to work together in pairs. We’ll revise some food vocabulary and the names of shops.

 

Dear daughter,

I have to work on Saturday, that’s why you should do the shopping and make a dinner. You have to make borsch and some salad. Here is 150 hryvnias. You may leave the change.

You must go to the baker’s and buy one loaf of bread (12 UAH) and four buns ( 5 per 1)

At the greengrocer you must buy half a kilo of potatoes ( 10 UAH per kilo), half a kilo of cabbage (8 UAH per kilo), 3 carrots (6 UAH), 2 onions (8 UAH), half a kilo of beet ( 12 UAH per kilo)

At the butcher’s, buy half a kilo of meat (120 per kilo)

 

So, how much is left for yourselves?

 

 

  1. Home Assignment.

 

There are two more tasks for your home assignment. If there are any problems with solving the tasks, translate them and ask your Math teacher for help.

 

  1. Tom and Mary had the same sum of money. When Tom bought a book for 14 pounds and Mary bought a doll for 6 pounds, then the girl had the money three times more than the boy.

How much money did everyone have at the beginning?

 

  1. There are 7 times more oranges in the first box than in the second one. When someone took 38 oranges from the first box, and 14 oranges from the second one, then there were 78 oranges less than in the first one. How many oranges were there in every box at the beginning?
