 Unit 4  Fractions

FractionsObjectives:
3.NF.1 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
3.NF.2 Understand a fraction as a number on the number line; represent fractions on a number line diagram.
a. Represent a fraction 1/b on a number line diagram by defining the interval from 01 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.
b. Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
3.NF.3 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 the same size or the same point on a number line.
b. Recognize and generate simple equivalent fractions. Explain why fractions are equivalent by using a fraction model.
c. Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.
d. Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, <, and justify conclusionsVocabulary Words:
Fraction  a number that represents part of a wholeDenominator  the bottom number in a fraction that tells what size the pieces areNumerator  the top number in a fraction that tells how many are shadedEquivalent Fraction  fractions that have the same valuePartition  to divideUnit Fraction  a fraction with a numerator of 1Whole Number  the numbers 0, 1, 2, 3, 4 ...Websites:I have listed several websites below that will be helpful to you during this unit. Some of the websites have online games, others have worksheets that may help you practice with these skills. Feel free to use as much or as little as you'd like.
