1. Finding multiples of a number.[br][list][br][*]Enter a number in the input box for the first denominator, for example 3.[br][/*][*]Click repeatedly on the Add Parts button. Notice what is the number of New Parts when the green light appears and try to predict when it will appear again[/*][/list]2. Common multiples and the least common multiple.[list][*]Enter numbers in the boxes for both denominators, for example 4 and 6.[br][/*][*]Click repeatedly on the Add Parts button. Notice what is the number of New Parts when both green lights are on.[br][/*][*]Continue to add new parts until both lights are on again.[br][/*][*]Discuss the significance of the first appearance of both green lights.[br][/*][*]Discuss the significance of the number of new parts in each original division when both green lights are on.[/*][/list]3. Writing fractions with common denominators. [list][*]Enter two fractions, for example, 3/4 and 1/6.[br][/*][*]Click repeatedly on the Add Parts button until you find the LCD.[br][/*][*]Enter two numbers in the input boxes for the numerators so that the two new fractions are equivalent to the original fractions and have the same denominators.[br][/*][*]Add more new parts until you find another common denominator.[br]Enter the numerators of the equivalent fractions using this new denominator.[br][/*][/list]
