Students may see the pattern and see that to multiply fractions, one may multiply the numerators and multiply the denominators. Students should be provided opportunities to work with real-life contexts and situations to model in order to give them experiences they need to develop understanding of what is happening when they multiply a fraction by a fraction. The goals of the standards are to build both understanding and computational fluency. When beginning with models to build understanding, students can make sense of the process as well as their answers. Students will use exploration with models and patterns to build towards understanding why when multiplying fractions, the numerators of the two fractions can be multiplied as well as the denominators.Īlthough memorizing rules may allow students to find the product, their understanding of multiplication of fractions allows them to solve real and mathematical problems that require this skill. In this Unit, students will build upon the understanding acquired from work with multiplying fractions of whole numbers and multiplying fractions with unit fractions. 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. MAFS.5.NF.2.5: Interpret multiplication as scaling (resizing), by:Ī. 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. By the definition of a fraction (in the case that the unit is the area of the unit square), its area is the. Multiply fractional side lengths to find area of rectangles and represent fraction products as rectangular areas. Consider the shaded rectangle in the picture. Therefore, 3 squares are required to cover the surface of the rectangle. Expert: Jimmy Chang Filmmaker: Christopher Rokosz Series Description: Fractions. 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 fractions to find the area of a rectangle with help from a mathematics educator in this free video clip. No later than third grade.7 Fractions Fractions have many interpretations. For example, use a visual fraction model to show, and create a story context for this equation. In other words, any triangle has half the area of an enclosing rectangle. Interpret the product as a parts of a partition of q into b equal parts equivalently, as the result of a sequence of operations a x q ÷ b. Celebrate our birthday with a 60 off present when you register for MrN 365- the subscription, ad-free, all-content, teacher-curated, enhanced feature version of. MAFS.5.NF.2.4: Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.Ī. Nussbaum - Area and Perimeter of a Rectangle with Fractions- Online.
