Learning goals: Unit at a Glance Sub-Unit 1: Fraction Multiplication (Lessons 1–10) • Recognize `\frac{a}{b}\times\frac{c}{d}=\frac{a\times c}{b\times d}` and use this generalization to multiply fractions numerically. • Represent and describe multiplication of a fraction by a fraction using area concepts. • Make generalizations about multiplying a whole number by a fraction greater than, less than, and equal to `1`. Sub-Unit 2: Fraction Division (Lessons 11–15) • Divide a unit fraction by a whole number using whole-number division concepts. • Divide a whole number by a unit fraction using whole-number division concepts. • Use the relationship between multiplication and division to represent multiplicative situations involving fractions with equivalent multiplication and division equations.
