. . . Parts of the whole Frankenstein's Fractions Fractions are parts of a whole! http://vimeo.com/31149799 Fractions can be different sized pieces of a whole… ½ of the pizza, 1/3 of the pizza, or ¼ of the pizza, Or, fractions can be different counts or beats of music as in the following video… http://www.tv411.org/math/fractions-decimalspercentages/whats-fraction/activity/1/1 Most of the time, fractions of the same item have the same denominator (the denominator is the number on the bottom of the fraction telling how many parts will make the whole). But sometimes two different items are put in the same group that have been divided differently and all the parts need to added together. For example, Suzi wants to add her ½ banana to the pie recipe and David wants to add ¼ of his banana to the pie. How much banana will be added in all? ½ + ¼ =? You need to find the common denominator. Using a visual model http://www.pbslearningmedia.org/resource/mgbh.math.nf.addfrac/additionof-fractions-using-a-visual-model/ Wrapping it up . . . Fractions are used in everyday life: To tell time- 12:30 is half past the hour to measure- 4 oz. of chocolate is ¼ lb. to cook – ½ cup of flour To calculate Money- 4 quarters are $1.00 Let’s practice! http://quizlet.com/6447606/flashcards http://lsintspl3.wgbh.org/en-us/lesson/mwnet-ilprobeco/1
