What will you learn in this lesson?

Students round fractions to 0, 1/2, or 1 by comparing the numerator with the denominator, so they can estimate amounts quickly, as in measuring and cooking.

  • Rounds fractions to 0, 1/2, or 1
  • Uses a number line to round fractions
  • Rounds mixed numbers to the nearest half

💡 Tip: Compare the numerator with half the denominator: if it is close to zero, round to 0; if it is close to half the denominator, round to 1/2; if it is close to the denominator, round to 1.
