Jump the Hoops With Powers of Ten

We laid six hoops on the floor, and in each hoop with put a card with one of the powers of ten, including ten to the zero power. Then the girls would read a number, and translate it into scientific notation while stepping in the correct hoop. For example, if they read the number 3526, this is how they would do it:
They would first determine which hoop to start in--in this case it would be the one with the card that says 10 to the 3rd power. They would jump in that hoop and say "three times 10 to the third power plus", then they would jump into the next hoop and say "five times ten to the 2nd power (then jump to the next hoop) plus two times ten to the 1st power (then jump) plus six times ten to the zero power.
