Step 1: Let's Learn

Read it, or press Listen and follow the words.

The counting words always come in the same order. One to ten, every time, for everything.

Why the order can never change

If the words came in a different order each time, the last one would change too. Then it could not tell you how many.

One number each

Every object gets exactly one number, and every number gets exactly one object. Nothing counted twice, nothing skipped.

The two ways it goes wrong

Counting one thing twice makes your answer too big. Missing one makes it too small. Both happen when your finger and your voice get out of step.

How many altogether

The last number you say tells you how many there are. You do not count again to find out โ€” the counting already answered it.

The number belongs to the group

Seven is not the name of the last object. Seven is how big the whole set is.

Step 2: Try It Yourself

Tap to add. Count out loud each time.

Tap to add an apple. Say the number each time.

How many in all7

Step 3: Watch an Example

One step at a time.
