You should already be able to count up to 1000 in English. The ordinary "cardinal" numbers were covered in Lessons 5, 15 and 20.
Cardinal numbers express quantity: two (2), thirty-five (35) etc...
Ordinal numbers indicate order or rank: first (1st), second (2nd), third (3rd) etc...
The definite article "the" normally goes in front of an ordinal number: e.g. "Queen Elizabeth the second."
For most ordinal numbers, the ending '-th' is used, with one or two exceptions for those inevitable irregular numbers:-
