13. Match the ending sound 3. For numbers 21st to 100th - The pattern repeats every ten: Look at the last digit (like 21, 32, 43). If the last digit is 1, it ends in " st " (21st, 31st). If the last digit is 2, it ends in " nd " (22nd, 32nd). If the last digit is 3, it ends in " rd " (23rd, 33rd). If the last digit is 4-9 or 0, it ends in " th " (24th, 25th, 30th).
