3 6 10 33 Lesson 5 Decompose unit tractions using area models to show equivalence EUREKA MATH +. You can expect to see homework that asks your child to do the following: Decompose fractions as a sum of unit fractions (e.g. They show how fractions can be expressed as the sum of smaller fractions by using different models. Represent the decomposition as a sum of unit fractions and as a multiplication sentence. In these lessons, students explore fraction equivalence. Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. Transcribed image text: 2 Draw an area model to show the decomposition represented by the number sentence below. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. Engage NY Module 5 A-5 Decompose unit fractions using area models to show equivalence. Engage NY Module 5 A-4 - Decompose fractions into sums of smaller unit fractions using tape diagrams. Decompose Fractions Using Area Models Decompose fractions using area models to show equivalence. Engage NY Module 5 A-3 - Decompose non-unit fractions and represent them as a whole number times a unit fraction using tape diagrams. For example, use a visual fraction model to represent 5/4 as the product 5 × (1/4), recording the conclusion by the equation 5/4 = 5 × (1/4).ī. Apply understanding of unit fractions and specifying the whole to number line. Problem 3: Decompose to build equivalent fractions in drawing an zone model and then share the area model include smaller parts. Understand a fraction a/ b as a multiple of 1/ b. Problem 1: Use a area scale to show that 3/4 6/8 Problem 2: Draw an territory model to represent the equivalence of two fractional and express the equivalence as the sum and product of unit fractions. Adding and subtracting fractions with like denominators word problemsįraction word problems with unlike denominatorsĤ.NF.B.4, 4.NF.B.4a, 4.NF.B.4b, 4.NF.B.4cĪpply and extend previous understandings of multiplication to multiply a fraction by a whole number.Ī.
