Lesson 6: Using Equivalent Fractions to Add Fractions with Unlike Denominators Numerically 2 Students will know… Adding and subtracting fractions with unlike denominators; Culminating Task: 2 Cindy’s Cats the numerator tells the number of parts and the denominator (Post-Assessment) tells the size of the parts Mixed numbers represent a whole number plus a fraction less than one Students will be able to… Use models to represent fractions and solve addition and subtraction problems with unlike denominators. Use benchmark fractions to reason about fractions. Identify the whole in a fraction context Write fractions in measures of a specific unit. Subtract mixed numbers and fractions with unlike denominators without regrouping Culminating Task: 2 Cindy’s Cats On-line Resources Text Resources Georgia Department of Education California Mathematics: Concepts, Skills, and Problem Solving: Grade 5.
