![]() ![]() Model the decomposition of a fraction in multiple ways, using models and pictures.Įx: 3/4 may be decomposed as 1/4, 1/4, 1/4, or 2/4 and 1/4. Addition & Subtraction Assessment - This lesson includes an awesome review game for the entire class, as well as an assessment of fraction composition/decomposition understandings.Fraction Game -In this interactive app, students apply their knowledge of fraction decomposition and equivalence to compose various fractions equivalent to one.The task and exit ticket both involve decomposition fractions having a denominator of 4 depending on the degree of challenge desired, these fractions could be adjusted so that the students were working with larger-digit. Teresa’s Pizza- This task-based lesson provides opportunities for students to demonstrate their understanding of fraction decomposition.Decomposing and Composing Fractions- In this lesson, students identify real-world situations when it would be helpful to know how to decompose and compose with fractions, then gives discussion guidance and student practice opportunities.When presented as written, this lesson will take at least 2 class periods. The lesson author explains her reasoning very thoroughly, and provides a wealth of resources, including pics of student work and videos of students explaining their thinking. Decomposing a Submarine Sandwich - In this introductory task, students will focus on decomposing a whole into a sum of unit fractions in a variety of ways, using paper models of a submarine sandwich.Planting a Garden - This hands-on task is designed to encourage students to think about the different ways a fraction can be decomposed.īig Ideas for Development Lessons 2 Weeks (approximately 1 week per big idea)īig Idea 1: We can use a variety of manipulatives and pictorial models to decompose fractions and record the results with symbolic representations. We can use models to add and subtract fractions with like denominators in real world and mathematical situations.We can use a variety of manipulatives and pictorial models to decompose fractions and record the results with symbolic representations.How can we communicate a fraction sum which is greater than one? What is the relationship between fraction operations and whole number operations? How can non-unit fractions be decomposed? How does adding and subtracting fractions help you solve real world problems?
