  1. Critical thinking
  2. Critical thinking is a domain- general thinking skill. The ability to think clearly and rationally is important whatever we choose to do.
  3. It includes the ability to engage in reflective and independent thinking. Someone with critical thinking skills is able to do the following : • understand the logical connections between ideas • identify, construct and evaluate arguments • detect inconsistencies and common mistakes in reasoning • solve problems systematically • identify the relevance and importance of ideas • reflect on the justification of one’s own beliefs and values
  4. Critical thinking enhances language and presentation skills. Thinking clearly and systematically can improve the way we express our ideas. In learning how to analyse the logical structure of texts, critical thinking also improves comprehension abilities.
  5. Critical thinking promotes creativity .To come up with a creative solution to a problem involves not just having new ideas. It must also be the case that the new ideas being generated are useful and relevant to the task at hand. Critical thinking plays a crucial role in evaluating new ideas, selecting the best ones and modifying them if necessary.

  18. Numbers •1. Cardinal numbers •2. Ordinal numbers •3. Fractions and decimals
  19. Cardinal numbers • 379= three hundred and seventy nine 2,860=two thousand eight hundred and sixty 5,084=five thousand and eighty four 470,000=four hundred and seventy thousand 2,550,000=two million, five hundred and fifty thousand 3,000,000, 000=three billion NOTE: There is no plural ‘s’ after hundred, thousand, million and billion when they are part of a number. On their own, they can be plural, e.g. thousands of people, millions of insects
  20. Ordinal numbers and dates • One of the problems with dates is that we write them and say them in a different way: • We write 4 January (or 4th January), but say the fourth of January or January the fourth. We write 21 May (or 21st May), but say the twenty-first of May or May the twenty-first. 1997=nineteen ninety seven 1905=nineteen hundred and five or nineteen oh five • 2020 = two thousand and twenty • 2002 = two thousand and two
  21. Fractions and decimals • 1 ¼ = one and a quarter 1 ½ = one and a half 1 ¾ = one and three quarters 2/3 = two thirds 4/9 = four ninth 1.25= one point two five 1.5=one point five 1.75= one point seven five 1.33= one point three three
  22. Money • Currency symbols (€, £, $ etc) should be placed before the number, with no space, like this: He earned €30,000 last year (spoken – thirty-thousand euros). $5 = five dollars £99.99 = ninety-nine pounds ninety-nine pence $198.1 billion– one hundred and ninety-eight point one billion dollars. Thousands should be separated by commas, like this: €2,901 (spoken – two-thousand, nine-hundred and one euros). • Decimals (cents, pennies etc) should be separated by a dot/point/full-stop (whatever you want to call it), like this: €12.99 (spoken – twelve euros, ninety nine cents – or just – twelve ninety-nine).
  23. Arithmetic There are four basic processes for working out (=calculating) a problem: = addition e.g. 6+4 = 10 (six plus/and four equals/ is ten) = subtraction e.g. 6-3 = 2 (six minus four equals/is two) = multiplication e.g. 6 4= 24 (six times/mulpitlied by four equals/is twenty- four) = division e.g. 4 2 = 2 (four divided by two equals/is two).
  24. Percentages 26%=twenty –six per cent More than 50% is the majority; less than 50% is the minority. • Saying ‘ 0 ‘ This can be spoken in different ways in different contexts. Telephone number: 603 724 = six oh three, seven two four ( AmEng = six zero three) mathematics: 0.7 = nought point seven, 6.02 = six point oh two temperature: -10 degrees = ten degrees below zero / minus ten degrees football: 2-0 = two nil tennis: 40-0 = forty love
