Phase:
After/Explain/Elaborate
Activity:
Once students have investigated and explored the concept of decomposing a fraction as a sum of fractions with the same denominator in more than one way using equations, this activity can be used to give the students an opportunity to explain their thinking and elaborate on the concept.
Students will complete the Decomposing Fractions Assessment Activity. Allow students to complete this activity individually then share their thinking with a partner or group of students. Students should explain their reasoning.
This activity can be used as an assessment or the teacher can lead a class discussion to allow students to share their reasoning with their classmates.
Assessment Strategies:
Student recordings on the Decomposing Fractions Assessment Activity sheet will be used as a formative or summative assessment to make sure students decompose a fraction using an equation as a representation.
Advanced Preparation:
Students should have prior knowledge of decomposing a fraction as a sum of fractions with the same denominator in more than one way using equations.
Variation Tips (optional):
Notes or Recommendations (optional):
15. Model and justify decompositions of fractions and explain the addition and subtraction of fractions as joining or separating parts referring to the same whole. a. Decompose a fraction as a sum of unit fractions and as a sum of fractions with the same denominator in more than one way using area models, length models, and equations. b. Add and subtract fractions and mixed numbers with like denominators using fraction equivalence, properties of operations, and the relationship between addition and subtraction. c. Solve word problems involving addition and subtraction of fractions and mixed numbers having like denominators, using drawings, visual fraction models, and equations to represent the problem.
