Adding and Subtracting Fractions
Students will:
MAFS.5.NF.1.1: 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.)LT 3.11: Create equivalent fractions with common denominators (including mixed numbers). (MAFS.5.NF.1.1)
MAFS.5.NF.1.2: 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.LT 3.13: Solve word problems involving addition and subtraction of fractions, with unlike denominators. (MAFS.5.NF.1.2)
MAFS.5.MD.2.2: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally.

Study those Math FACTS!!!
Please spend 10-15 minutes per night working on your basic multiplication facts. Students who do not have a ready recall of the basic facts will struggle to complete assignments in 5th grade. Invest now to make math easier later.
