Step 1: Let's Learn

Read it, or press Listen and follow the words.

Count the toys. The last number you say is how many toys there are.

The number is about the whole group

Six is not the name of the last toy. Six is how big the pile is. It belongs to all of them together.

Count again the other way

Start at the other end and count again. You still get the same number.

Why it comes out the same

The toys did not change. Only your finger went a different way. How many there are cannot depend on where you started.

That is how you check

Two counts, two different directions, same answer. Now you can be sure.

Step 2: Try It Yourself

Tap and try it out.

Count the balls. Then count them backwards. Same answer.
