CKMath Unit 2: Fractions as Quotients and Fraction Multiplication
Focus:
In this unit, students learn to interpret a fraction as a quotient and extend their understanding of multiplication of a whole number and a fraction. In grade 3, students made sense of multiplication and division of whole numbers in terms of equal-size groups. In grade 4, they used multiplication to represent equal-size groups with a fractional amount in each group and to express comparison. Here, students learn that a fraction can also represent a division situation or a fraction of a group. Students also interpret the product of a whole number and a fraction in terms of the side lengths of a rectangle. Using diagrams, the commutative and associative properties become evident as students connect different expressions to the same diagram.
