Assuming this is math reference, it is a group of numbers like 5, 8 and 3 that relate to each other 5+3=8, 3+5=8, 8-5=3, 8-3=5. It is basically teaching the students the commutative law without teaching it to them.

I was surprised to find them emphasizing the number families in math this last year, they were supposed to memorize all the different families... Isn't it easier to learn basic addition and subtraction? I guess I am getting old, I am starting to sound like my parents ;-)
