Three numbers, 352 718, 98 640 and 357 104, go into a place value chart with the ones lined up on the right, and the digits are compared from the left. 98 640 has 0 hundred thousands, so it is the smallest even though it starts with a 9; the other two match until the thousands, where 2 is less than 7, giving 98 640 < 352 718 < 357 104.

What the lesson says
Let's put 352,718, 98,640 and 357,104 in order, from smallest to biggest.
Write them in a place value chart, with the ones lined up on the right.
98,640 has no hundred thousands, so that place is 0.
Compare the digits from the left, starting with the hundred thousands.
0 hundred thousands is less than 3 hundred thousands.
So 98,640 is the smallest.
Even with 9 ten thousands, 98,640 is less than 100,000.
352,718 and 357,104 both have 3 hundred thousands.
They both have 5 ten thousands as well.
Next, the thousands. 2 thousands is less than 7 thousands.
So 352,718 is less than 357,104.
The thousands decide it, so there is no need to check the other places.
From smallest to biggest, the order is 98,640, then 352,718, then 357,104.
Line up the places, then compare the digits from the left.
