Grades: 4,5,6

Description: With this deck, students will practice adding and subtracting fractions with unlike denominators and simplify their answer to lowest terms. Students will also apply their computation skills to solve word problems that involve adding or subtracting fractions with unlike denominators. Common Core Standards: •CCSS.MATH.CONTENT.5.NF.A.1 - 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 or difference 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.) •CCSS.MATH.CONTENT.5.NF.A.2 - Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
