#DECOMPOSE FRACTIONS USING AREA MODELS TO SHOW EQUIVALENCE. HOW TO#
Decompose the shaded unit fractions as the sum of smaller unit fractions in at least two different ways. VDOMDHTMLtml> Grade 4 Common Core Eureka Math: Decompose unit fractions using area model Module 5 Lesson 5 - YouTube This video breaks down how to decompose unit fractions using. The total length of each tape diagram represents 1. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. Eureka Math 4th Grade Module 5 Lesson 4 Homework Answer Key. Problem 3: Decompose to create equivalent fractions by drawing an area model and then dividing the area model into smaller parts. Their work is justified using area models and tape diagrams and, conversely, multiplication is used to test for and/or verify equivalence.
Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. Problem 1: Use an area model to show that 3/4 6/8 Problem 2: Draw an area model to represent the equivalence of two fractions and express the equivalence as the sum and product of unit fractions. Fraction Equivalence, Ordering, and Operations OVERVIEW. Topic B Fraction Equivalence Using Multiplication and Division 4.NF.1, 4.NF. Lesson 6 Decompose fractions using area models to show equivalence. Lesson 5 Decompose unit fractions using area models to show equivalence. 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. Decompose fractions into sums of smaller unit fractions using tape diagrams. Understand a fraction a/ b as a multiple of 1/ b.
