In this lesson, the third of a seven-part unit from Illuminations titled “Fun with Fractions: A Unit on Developing the Set Model,” students use twelve eggs to identify equivalent fractions. Construction paper cutouts are used as a physical model to represent various fractions of the set of eggs. Students investigate relationships among fractions that are equivalent.

Grade 3
- Goal 1: Number and Operations - The learner will model, identify, and compute with whole numbers through 9,999.
- Objective 1.05: Use area or region models and set models of fractions to explore part-whole relationships.
- Represent fractions concretely and symbolically (halves, fourths, thirds, sixths, eighths).
- Compare and order fractions (halves, fourths, thirds, sixths, eighths) using models and benchmark numbers (zero, one-half, one); describe comparisons.
- Model and describe common equivalents, especially relationships among halves, fourths, and eighths, and thirds and sixths.
- Understand that the fractional relationships that occur between zero and one also occur between every two consecutive whole numbers.
- Understand and use mixed numbers and their equivalent fraction forms.
- Objective 1.06: Develop flexibility in solving problems by selecting strategies and using mental computation, estimation, calculators or computers, and paper and pencil.
- Objective 1.05: Use area or region models and set models of fractions to explore part-whole relationships.
