Divide Unit Fractions in Context

Learners discover that a fraction is a division (3 ÷ 4 = 3/4) by sharing pizzas and granola bars, then divide a unit fraction by a whole number and a whole number by a unit fraction with bars and number lines. Every quotient is checked with multiplication, and the final lesson asks learners to decide which division a story describes.

  • 4 lessons
  • About 80 minutes
  • Unit-fraction division check: 10 questions
  • Ways to answer: choose an answer, type a fraction, match pairs, type a number, place on a number line and sort into groups

What learners will discover

  • Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b) in sharing situations.
  • Divide a unit fraction by a whole number using models, and check the quotient with multiplication.
  • Divide a whole number by a unit fraction using models, and explain why the quotient is greater than the whole number.
  • Decide which division a story describes and solve real-world problems with unit fractions.
