Count Forward - Up to 100

Do this: Read the concept below, then try the quiz or activity.

Lesson 101 of 180

Concept

Do you know the trick to counting into big numbers? You just have to know your tens!

🎯 The 0-9 Pattern: Every single group of tens does exactly the same thing. They all count up from 0 to 9 in the "ones" place. * Twenty-1, Twenty-2, Twenty-3... Twenty-9! * Fifty-1, Fifty-2, Fifty-3... Fifty-9!

🎯 Turning the Corner: The only tricky part is knowing what word comes AFTER the number that ends in 9. You have to "turn the corner"! * What is after 29? Thirty (30). * What is after 39? Forty (40). * What is after 49? Fifty (50)... followed by 60, 70, 80, 90, 100!

If you know the order of those big "Tens" words, you can easily count all the way to 100.
