### 5.NF.1

 Standard(s) Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum ordifference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)Rubric:Assessment:Curriculum Lessons:Do the Math: Fractions C *Used in the Gap plan 2012Adding and Subtracting With Like Denominators (5 Lessons)*These lessons do not include all of the standard but most likely will be needed preceding the adding and subtraction of unlike denominators.Adding and Subtracting With Unlike Denominators (5 Lessons)Practice Adding and Subtracting Using Sequences of Equivalent Fractions (5 Lessons)Compute and CompareFraction IslandsImproper Fractions and Mixed Numeral Equivalents 6-2 * not actually adding and subtracting fractions but exploring the meaning of fractions and mixed numbersFraction Islands 10-1Fraction Islands 10-2Subtraction Modeled as Comparing 11-1Additional LessonsExit Tickets/TasksWebsites:Adding FractionsRogers School District (scroll down to Single day lessons.
