Adding and subtracting fractions 22/05/2014 Objective: I should be able to add and subtract fractions. (L5-6/Grades E-D) Keywords: numerator, denominator, simplify, equivalent By the end of the lesson: Must learn: to add and subtract fractions with a common denominator. (5c/E-) Should learn: to add and subtract fractions with different denominators. (one change) (5a/E+) Could learn: to add and subtract fractions with different denominators.(two change) (6c/D-) Real life link: You might need to add or subtract distances involving fractions.
