Multiply Fractions

Lesson(s): 7.1–7.3, 7.6
Apply and extend previous understandings of multiplication and division to multiply and divide fractions. MAFS.5.NF.2.4 Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction. a. Interpret the product (a/b) 3 q as a parts of a partition of q into b equal parts; equivalently, as the result of a sequence of operations a 3 q 4 b.
Lesson(s): 7.4, 7.7
Apply and extend previous understandings of multiplication and division to multiply and divide fractions. MAFS.5.NF.2.4 Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction. b. Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to fi nd areas of rectangles, and represent fraction products as rectangular areas.
Lesson(s): 7.5, 7.8
Apply and extend previous understandings of multiplication and division to multiply and divide fractions. MAFS.5.NF.2.5 Interpret multiplication as scaling (resizing), by: a. Comparing the size of a product to the size of one factor on the basis of the size of the other factor, without performing the indicated multiplication.
Lesson(s): 7.5, 7.8, 7.10
Apply and extend previous understandings of multiplication and division to multiply and divide fractions. MAFS.5.NF.2.5 Interpret multiplication as scaling (resizing), by: b. Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number; and relating the principle of fraction equivalence a/b 5 (n 3 a)/(n 3 b) to the effect of multiplying a/b by 1.
Lesson(s): 7.9
Apply and extend previous understandings of multiplication and division to multiply and divide fractions. MAFS.5.NF.2.6 Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
