# Math – Oct. 16th -Oct. 27

Teacher Brittnee Zeak Math 5 11-12 Adding /Subtracting Fractions
Standard(s) Taught

*NEW*

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.)

Learning Targets and Learning Criteria

Students will:

• apply concepts of factors, multiples, equivalent fractions, and decomposition of fractions to find like denominators. (This is a 4 th grade skill.)
• represent addition and subtraction of fractions, including mixed numbers and fractions greater than 1, with unlike denominators using concrete models, graphical models, and equations (denominators are limited to 1-20).
• add up to three fractions including mixed numbers and fractions greater than 1.
• subtract fractions including mixed numbers and fractions greater than 1.
• solve for an unknown numerator or denominator in an addition or subtraction problem given the sum or difference.
