Goal of the lesson:
To know the days of the week /
months in a year/ ordinal numbers in the correct order and spelling.

#### Slide 1 -Tekstslide

Rule over days/months:
Always with a capital letter!
(Altijd met een hoofdletter!)

#### Slide 2 -Tekstslide

Rules over ordinal numbers:
* Difference formal/informal writing.
1st=informal
first=formal

#### Slide 3 -Tekstslide

Single digit numbers:
Look at these and notice the last two letters of the words
1st = first
2nd = second
3rd = third
4th = fourth
5th =fifth

#### Slide 4 -Tekstslide

Last two letters of the words= make up the ordinal number
first - last two letters are 'st' so put after 1 = 1st
second - last two letters are 'nd' put after 2 = 2nd
third - last two letters are 'rd' so put after 3 = 3rd
4th - last two letters are 'th' so put after 4 = 4th

#### Slide 5 -Tekstslide

Teen numbers:
14th = fourteenth (fourteen + th)
15th = fifteenth (It's her fifteenth birthday.)
16th = sixteenth
17th = seventeenth
18th = eighteenth
19th = nineteenth.

#### Slide 6 -Tekstslide

Long numbers:
'th' is added to the last number:
106th = one hundred and sixth
242nd = two hundred and forty-secondth
2018th = two thousand and eighteenth

#### Slide 7 -Tekstslide

Spelling rules:
4th - We have four, fourteen, forty(drop the u), fourth (don't drop the 'u')
5th - We have five, but then the 'v' become 'f' in fifteen, fifty, fifth ( the 'f' helps pronunciation)
9th - We have nine, nineteen, ninety, but ninth (drop the 'e')
12th - twelve, twelfth (Notice the 'v' becomes 'f')

#### Slide 8 -Tekstslide

Numbers from 21 upwards:
We need a hyphen when we write cardinal numbers from 21 upwards. There's no space between the letters and hyphen:
twenty-one
twenty-two
thirty-three
sixty-seven
one hundred and twenty-nine

#### Slide 9 -Tekstslide

Using a hyphen also applies to ordinal numbers from 21st.
twenty-first = 21st (It's her 21st on Sunday.)
twenty-second
twenty-third = 23rd
thirty-second = 32nd
thirty-third = 33rd
forty-third = 43rd
forty-fourth = 44th
fifty-third = 53rd
fifty-fifth = 55th
