Learning goals

  • Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts
  • Identify shaded fractional parts of bar models
  • Differentiate numerator (shaded pieces) and denominator (total pieces)

Before you begin

Recognize one whole divided into equal parts.

Teaching and response guide

  1. Model the target skill: understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts. Use the first task as a guided example before asking for an independent response.
  2. Check readiness first: Recognize one whole divided into equal parts.
  3. Discuss an incorrect response using this distinction: Count all equal parts for the denominator and shaded parts for the numerator; unequal parts do not support the same fraction model.

Watch for: Count all equal parts for the denominator and shaded parts for the numerator; unequal parts do not support the same fraction model.

Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
