Task statements for students to write on. Unit: 5.3 Multiplying and Dividing Fractions (Grade 5). 5.3 Multiplying and Dividing Fractions Unit Goals Students extend multiplication and division of whole numbers to multiply fractions by fractions and divide a whole number and a unit fraction. Section A Goals Recognize that $\frac{a}{b} \times \frac{c}{d}=\frac{a \ \times \ c}{b \ \times \ d}$ and use this generalization to multiply fractions numerically. Represent and describe multiplication of a fraction by a fraction using area concepts. Section B Goals Divide a unit fraction by a whole number using whole-number division concepts. Divide a whole number by a unit fraction using whole-number
