5.CE.2

The student will estimate, represent, solve, and justify solutions to single-step and multistep problems, including those in context, using addition and subtraction of fractions with like and unlike denominators (with and without models), and solve single-step contextual problems involving multiplication of a whole number and a proper fraction, with models.

5.CE.2.aDetermine the least common multiple of two numbers to find the least common denominator for two fractions.5.CE.2.bEstimate and determine the sum or difference of two fractions (proper or improper) and/or mixed numbers, having like and unlike denominators limited to 2, 3, 4, 5, 6, 8, 10, and 12 (e.g., 5/8 + 1/4, 4/5 – 2/3, 3 3/4 + 2 5/12), and simplify the resulting fraction.5.CE.2.cEstimate and solve single-step and multistep contextual problems involving addition and subtraction with fractions (proper or improper) and/or mixed numbers having like and unlike denominators, with and without models. Denominators should be limited to 2, 3, 4, 5, 6, 8, 10, and 12. Answers should be expressed in simplest form.5.CE.2.dSolve single-step contextual problems involving multiplication of a whole number, limited to 12 or less, and a proper fraction (e.g., 9 × 2/3, 8 × 3/4), with models. The denominator will be a factor of the whole number and answers should be expressed in simplest form.
