Step 1: Let's Learn

Read it, or press Listen and follow the words.

Three apples and two apples. Push them together and count them all.

That is what adding is

Adding is putting groups together and asking how many there are now. Nothing appears or disappears.

The plus sign

We write it 3 + 2. The + means put together. It saves saying the whole sentence every time.

The equals sign

3 + 2 = 5 says both sides are the same amount. It does not mean "here comes the answer".

Equals means balanced

You could write 5 = 3 + 2 and it would still be true. Both sides name the same amount, whichever way round you put them.

Step 2: Try It Yourself

Tap and try it out.

Put in three, then two more. Count them all.

How many5

5 more would make 10.
