[L3] Recycling in Fractions!
Practice
Lesson 3 to practice generating equivalent fractions using recycling fractions from different states in the United States. CC Standard: 4.NF.A.1: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. Practice Lesson 3 Context: Recycling in Fractions! Graphs: Bar graph Number of questions: 15 Difficulty level: Medium Estimated time: 15 mins
Recycling in Fractions! Every day, people put paper, plastic, and metal into recycling bins to help care for the Earth. When the materials are collected, each state recycles a different portion of its waste, and this amount is measured out of 100%. In this lesson, you will use fractions to represent these recycling amounts and discover equivalent fractions — different fractions that describe the same amount of recycling. Click Next to begin!
