When we count things, we say "one, two, three ..."
When we talk about dates, birthdays etc. in English, we need to use ordinal numbers.
Cardinal numbers = one, two, ... ten 代表個數
Ordinal numbers = first, second, ... tenth 表示順序、等第、等觀念
Practice these numbers with a memory game for two players here:

More practice with a spelling game here (這個遊戲很刺激,看到 "one" 要趕快拼 "first," 看到 "two" 要趕快拼 "second"。玩玩看吧!)

Have fun practicing!
