Transcript of Equivalent Fractions

Equivalent Fractions... Equivalent Fractions Key Vocabulary a NUMERATOR is the top number in a fraction. It describes how many pieces of the whole are left. are fractions that show the same amount of the whole, BUT the form of the fraction changes. Common Core Standard 3.NF.3 Number & Operations - Fractions Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
a. Understand two fractions as equivalent (equal) if they are thesame size, or the same point on a number line.
b. Recognize and generate simple equivalent fractions, e.g., 1/2 =2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., byusing a visual fraction model.
c. Express whole numbers as fractions, and recognize fractions thatare equivalent to whole numbers. Examples: Express 3 in the form3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same pointof a number line diagram.
d. Compare two fractions with the same numerator or the samedenominator by reasoning about their size. Recognize thatcomparisons are valid only when the two fractions refer to thesame whole. Record the results of comparisons with the symbols>, =, or <, and justify the conclusions, e.g., by using a visualfraction model. Develop an understanding of fractions as numbers Learning Targets I will be able to define equivalent fractions. I will be able to solve equivalent fractions. A fraction is a number that can
represent a part of a whole. Remember... a DENOMINATOR is the top number in a fraction. It describes how many pieces are in the whole. Review numerator denominator 1 2 1/4 = 2/8 = 4/16 The word equivalent begins like the word equal. Did you notice? Equivalent fractions are equal to each other. They show the same amount even if they have different number of pieces. Always Remember The key to equivalent fractions is to multiply the both the numerator and the denominator by the same number. Let's Work Some
Problems Create 5 of your own equivalent fractions and
swap with your
neighbor. Extend
the equivalent
fractions 3 times by
solving. Time: 10 minutes Practice equivalent fractions on your iPad
with one of these games!
