Teacher: Let’s try this another way! If I give you two apples and two apples and another two apples, how many apples have you got? Paddy: Six.
Teacher: Good. Now if I give you two rabbits and two rabbits and another two rabbits, how many rabbits have you got? Paddy: Seven.
Teacher: How on earth do you work out that three lots of two rabbits is seven? Paddy: I’ve already got one rabbit at home.
