A mixed pile of bills and coins is lined up from the largest to the smallest and counted on, 20, 40, 60, 70, 72, 74, 75, then checked: $60 + $10 + $4 + $1 = $75. The same $75 is then made a second way with a $50, a $20 and a $5, showing that one amount can be made in different ways.

What the lesson says

How much money is in this pile?

Line them up, starting with the largest.

Count the twenty-dollar bills by twenties: 20, 40, 60.

Count on 10 for the ten-dollar bill: 70.

Count on by twos for the two-dollar coins: 72, 74.

Count on 1 for the one-dollar coin: 75.

So there are 75 dollars in the pile.

Let's check what each kind makes: 60, 10, 4 and 1.

60 plus 10 plus 4 plus 1 is 75.

Now make 75 dollars a different way.

Start with the largest, a fifty-dollar bill: 50.

Count on 20 for a twenty-dollar bill: 70.

Count on 5 for a five-dollar bill: 75.

Both ways make 75 dollars.

Start with the largest, then count on.
