Tens to 100
The fastest way to count to 100 is to count in tens. Listen how it sounds:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
Just ten numbers and you are at one hundred. That is the trick everyone uses to count crowds, candies in a jar or pages in a book.
The names
Each one has a name that ends with -ty:
- 20 = twenty
- 30 = thirty
- 40 = forty (no "u" in this one!)
- 50 = fifty
- 60 = sixty
- 70 = seventy
- 80 = eighty
- 90 = ninety
The number 100 is called "one hundred". You can also say "a hundred".
How they look written
The pattern is simple — every full ten ends with a 0:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100.
The first digit is "how many bags". The 0 means "no loose marbles".
Practice tip
Say the tens out loud while you walk: "ten" (step), "twenty" (step), "thirty" (step). By the time you say "one hundred" you have walked ten steps. Easy.
