When dividing you are asking how much of the divisor or how many divisors fit into the dividend.
Division of fractions using models. When you are dividing the fraction ½ by ⅓ you take your dividend fraction or what is being divided ½ and then split it into thirds. Youll gain access to interventions extensions task implementation guides and more for this instructional video. Figure 2 shows Lamons 2012 area model for a division problem that addresses how many 23s there are in.
Model fractions as division using tape diagrams and solve word problems involving division of whole numbers with answers in the form of fractions or mixed numbers. Sentence and compute the answer using fractions when given a real-world situation. O Have students complete additional division-of-fractions problems using other representations such as arrays paper folding repeated addition repeated subtraction fraction strips or pattern blocks.
Collect and assess students understanding using Attachment B Division Assessment. The default example above pictures with circle models the division of 1 3 4 by 2 3.
It is both a hands-on activity as well as a digital activity. This product is a Google Slide Show. I Can Divide Fractions Using a Visual Model.
Use the relationship between multiplication and division to explain that 23 34. Understanding the Models to Teach Dividing Fractions. Explain how to use fraction strips to divide a fraction by a fraction.
Students then practice figuring out how many or what portion of the divisors fill the divi. Use the I Do We Do You Do model also known as a gradual release model of instruction to guide students through the process of using the strips. Dividing fractions with models is a great way to introduce your students to the concept of dividing by a fraction.
In this lesson you will learn how to divide fractions by fractions by using models. Interpret and compute quotients of fractions and solve word problems involving division of fractions by fractions eg by using visual fraction models and equations to represent the problem. One model used to conceptualise division of fractions is an area model.
For example create a story context for 23 34 and use a visual fraction model to show the quotient. In some division of fraction problems you can only make a partial group. Students divide fractions using models in this activity that reinforces visual understanding of this tricky topic.
Multiplying a Fraction by a Whole Number 3 5NFB4A. Use models for division of fractions by fractions. Student should be able to model write and solve division problems that involve fractional.
Give each student a copy of Attachment A Division Assessment. O Use index cards with a division of fractions problem written on one card eg 31 43. Each card has blank models on it that represent the fractions and their common denominators.
Involving division of fractions by fractions eg by using visual fraction models and equations to represent the problem. Dividing Fractions using fraction models. This video is an example on how to solve the division of fractions using an area model.
