Numbers on a computer screen

Talk about numbers and percentages

大きな数、パーセンテージ、比較といった数字に関する表現に取り組みます。

Introduction

Describe the graph below. Use numbers as much as possible. 

Your student should point out:

  • The incidence rate is per 100,000 persons employed.
  • Romania is the highest, at about 5.5 per 100,000 (five-point-five per hundred thousand).
Warm Up

How comfortable are you reading and using numbers?

Students should be able to deal with numbers effortlessly.

  • Thinking about how to say a number means you have to take attention away from something else.
    • If you use even just 10% of your attention figuring out how to say a number in English, that means the rest of your answer is going to be 10% worse. 
  • Numbers have to be right.
    • If you make even the slightest mistake with numbers, you will lose the trust of your client or colleagues. Some mistakes are easy to overlook. But numbers must be right.

Keep practicing until you can do it with zero effort.

Language

  • 1,700,000
  • 1,070,000,000
  • 10,912,094,809

2. 24% 
b. just under three-quarters 

3. 74%

  • How many ways can you describe this number: 25% 
  1. one in f________
  2. a q________
  3. one out of f________
  4. one out of every f________

C. Comparatives and superlatives

In lesson 17, we discussed the benefits of comparing two graphs. You can also compare information in one graph. Use the phrases below to complete the sentences, describing the graph in the Introduction.

  1. (by far) the most
    • In 2015, Romania had...
  2. (by far) the fewest
    • In 2014, Greece had...
  3. (far) more [A] than [B]
    • Latvia had...
  4. (far) fewer [A] than [B]
    • The Czech Republic had...
  5. nearly [number] times more
    • Compared with Greece, Romania had...

A. Big numbers

Read out the numbers below. 

  • 1,350 = one thousand, three hundred (and) fifty
  • 170,000 = one hundred seventy thousand
  • 1,700,000 = one million, seven hundred thousand.
  • 1,070,000,000 = one billion, seventy million.
  • 10,912,094,809 = ten billion, nine hundred (and) twelve million, ninety-four thousand, eight hundred (and) nine.

If your student has trouble, you can help them simply count commas:

B. Fractions/percentages

Match these percentages on the left (15), to the fractions on the right (ae).

1. 50% = (d) half

2. 24% = (a) nearly a/one quarter 

3. 74% = (b) just under three-quarters 

4. 33% = (c) approximately a/one third

5. 10% = (e) a/one tenth

How many ways can you describe this number? (25%

  • one in four
  • a quarter
  • one out of four
  • one out of every four

C. Comparatives and superlatives

In lesson 17, we discussed the benefits of comparing two graphs. You can also compare information in one graph. Use the phrases below to complete the sentences, describing the graph in the Introduction.

Sample answers:

  • (By far) the most
    • In 2015, Romania had by far the most accidents.
  • (By far) the fewest
    • In 2014, Greece had the fewest accidents.
  • (Far) more [A] than [B]
    • Latvia had more accidents in 2014 than in 2015.
  • (Far) fewer [A] than [B]
    • The Czech Republic had fewer accidents in 2014 than in 2015
  • Nearly [number] times more
    • Compared with Greece, Romania had nearly 5 times more accidents in both 2014 and 2015.
Practice

Present this graph to your teacher.

Make sure you give a clear overview using the skills and language you learned in lessons 17 and 18. Then describe the graph in detail using language from this lesson.
