First, I wrote the question and drew the 3 oranges, 2 pears and the banana.
Then, I drew my bar and coloured 1 for banana, 2 for pears and 3 for oranges.
After that, I added 1,2 and 3. My answer was 6.
I know that double 6 is 12 and doubling is the opposite of a half.
So 6 more cubes makes 12, that is how many apples there will be.
