In the classroom

Teaching tips & learning objectives

Learning objectives

  • Understand that rewriting a fraction with a common denominator changes its form, not its value.

Teaching tips

  • Have students explain why their rewritten fractions have the same value as the originals. A fraction model can help if they are applying the rule without understanding it.

  • Ask students to estimate the sum before calculating, then use the estimate to check whether their answer is reasonable.

Skills covered

  • Equivalent fractions — find a common denominator without changing the fractions’ values.

  • Adding fractions — combine fractional parts and whole numbers.

  • Regrouping — express sums greater than one whole in mixed-number form.

Standards

  • 5.NF.A.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.)
