Video Learning Notes

In this lesson, students learned to compose and decompose fractions a/b with numerator greater than zero and less than or equal to the denominator as sums of unit fractions 1/b. They practiced solving partitioning problems using pictorial fraction models and explored equivalent fractions using fraction strips and number lines. These skills build a strong foundation for understanding fractions and their relationships in real-world contexts.

Learning Goals

  • Compose a fraction a/b with numerator > 0 and ≤ b as a sum of unit fractions 1/b.
  • Decompose a fraction a/b with numerator > 0 and ≤ b as a sum of unit fractions 1/b.
  • Solve problems involving partitioning objects or sets among two or more recipients using pictorial fraction models with denominators 2, 3, 4, 6, and 8.
  • Represent equivalent fractions with denominators 2, 3, 4, 6, and 8 using objects, pictorial models, and number lines.
