Rolling Quarter Puzzle

As the quarter on the right rolls completely around the quarter on the left one time, how many times will the rolling quarter rotate fully around its own center during its journey? Visualize the quarter rolling without moving the slider and make a conjecture. Use two real quarters to test your conjecture and then use the model below to explain your observations.
