PrintThe Associative Property of Addition: When three or more numbers are added, the sum is the same, regardless of the order of addition. For example (2 + 3) + 1 = 2 + (3 + 1). Pretty simple. In other words: it doesn't matter how you add them, the totals are always same. (O O + O O O) + O is the same as O O + (O O O + O) because OOOOOO = OOOOOO and six equals six, (6 = 6) everyday of the week and twice on Sundays. This is so obvious with blocks kids may look at you funny when you explain it to them, math concepts are visually obvious when presented with manipulatives. Now just for fun (and this has very little to do with The Associative Property of Addition unless you set it up correctly) here is a problem that most little kids will find VERY difficult unless they have the blocks and some guidance from you.
