You will be shown fractions and decimals. You must use the mouse to drag them to the right place on the number line. If you are wrong, the fraction or decimal will explode and you must try again. You can change the number of pieces the distance between zero and one is divided into. Remember that the numerator of a fraction tells you how many pieces each whole is cut into. It will help you if you divide up the number line into as many pieces as the denominator. For decimals, it is usually easiest to convert the decimal to a fraction before trying to place it.
