Then you can recognize numbers in four groups
1. TEEN group
There are numbers: 13 - 19
all of them finish with the expression TEEN
There are some examples:
TEEN is equal TEENager = Adolescente
There are some exceptions:
thirTEEN
fifTEEN
...............................................................................................................................................................................................
2. TY group
There are numbers 20 - 90
all of them finish with the expression TY
There are some examples:
There are some exceptions:
2 = two 12 = twelve
20 = twenTY
3 = three
13 = thirTEEN
30 = thirTY
4 = four
14 = fourTEEN
40 = forTY
5 = five
15 = fifTEEN
50 = fifTY
...............................................................................................................................................................................................
3. HUNDRED group
And here start the real combination, you only need numbers one to nine and the word HUNDRED
Example:
ONE HUNDRED
FOUR HUNDRED
SEVEN HUNDRED
LET'S TRY TO DO THIS EXERCISE
*Write numbers......
800
125
564
250
948
...............................................................................................................................................................................................
4. THOUSAND group
Taking into account HUNDRED explanation, with Thousand you follow the same logic process, you write number one to nine and the word THOUSAND
Example:
THREE THOUSAND
FIVE THOUSAND
EIGHT THOUSAND
LET'S TRY TO DO THIS EXERCISE: Write the number in letters or in symbol
Let's try with some additions
8 + 6 = 10 + 22 = 319 + 127 =
2 + 9 = 38 + 23 = 864 + 461 =
7 + 5 = 66 + 44 = 1752 + 5340 =
4 + 3 = 83 + 97 = 6851 + 2439 =
