Teen numbers come before twenty.

Each next number is one more.

Read it: Count by ones on the line

After 37 comes 38: 1 tick on. After 59 comes 60: the ones run out, and a new ten starts.

  1. Find the number you are on: 37.
  2. Move 1 tick on.
  3. Say the next number: 38.

Each tick on the line is 1 more.

After a number that ends in 9, the ones start again at 0 and the tens go up: 59, then 60.

The same rule works all the way to 100: after 99 comes 100.

Counting by ones is 1 tick on. After a 9, a new ten starts.

Saying 50 after 59, as if the tens went back.

The tens go up: 59, then 60.

After 24 comes ___? — 25. 1 more than 24 is 25.

Counting from 1 to 30

Today we're going to count all the way up to thirty! Ready? Let's go.

First, let's count from one to ten. One, two, three, four, five, six, seven, eight, nine, ten!

After ten comes a tricky name — eleven.

Then another tricky one — twelve.

Now the rest of the teens: thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen.

After nineteen comes a brand new ten — twenty!

Now the twenties are easy: twenty-one, twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine.

And finally… thirty!

We counted all the way to thirty. Awesome counting!
