ADICION (FRACCION) (Español) ADDITION (FRACTION) (Français) From Wikieducator...a teaching approaches for addition of fractions From Wikipedia " ... Imagine a pocket containing two quarters, and another pocket containing three quarters; in total, there are five quarters....." From Wikibook reference 1 "Before we go into fractions, let's think about what addition is. Answer these questions: *What is 1 bird + 5 birds? *What is 3 elephants + 9 elephants? *What is 6 birds + 2 elephants? Hopefully you could answer the first two, but you might have had trouble with the third. Why? Because we can't add up two different things! ......" From Wikibook reference 2 [a method for additing fractions] From Wikiversity"Fractions that have the same or "Common" denominator are called "Like" fractions. 1/3, 2/3 (one-third, two-thirds) To add Like fractions together such as these: 1/3 + 2/3 = ? (one-third plus two-thirds equals what?) 1. Add the numerators (the top numbers): 1 + 2 = 3 (one plus two equals three) 2. Use the common denominator (the bottom numbers): /3 All together it looks like this: 1/3 + 2/3 = 3/3 (one-third plus two-thirds equals three-thirds)..... " |
