Adding and subtracting fractions with like denominators lesson plan
- 1. Tuesday, October 1, 2013 Adding and Subtracting Fractions with Like Denominators Student Expectation: Use addition, subtraction, multiplication and division to solve problems involving fractions and decimals Language Objective: Connect modeling addition and subtraction of fractions to the algorithm in our Miller Math Notes. Opening: Quick Start: Students will complete the worksheet on matching adding fraction equations to the visual representation. They will be given 5 minutes to solve as many problems as they can. We will review the answers as a class for 2 minutes. Teacher Instructions: We will begin by reviewing modeling addition and subtraction of fractions. We will discuss ways that we can create our own models when not given one to start with. We will then move into adding and subtracting fractions with simple fractions that require us to simplify at the end using the I DO, We DO, You DO method. After practicing with naked numbers, we will solve word problems using text coding and strategies taught. Key Vocabulary: Synonyms for adding and subtracting, sum, difference, common denominator, simplest terms, equivalence; perimeter, simplify, regroup Transitions/Processing Breaks: Ask students (Stop and Jots, Think-Pair-Share, Non-Volunteer Response Questioning) Process It: What is your tips list for solving these kinds of problems? Stop and Jot: Compare and contrast adding and subtracting fractions. How are they similar? Different? Guided Practice: Students will complete the Miller Math Notes guided by the teacher and with a partner. Independent Practice: Students will complete the Adding and Subtracting Fractions – Measurement Connection. Closing: Exit Ticket: Give an example of a real world situation where you would have to add or subtract fractions. How would you explain how to do it to your parents? Assessment: Questioning; teacher circulation during practice; quick write at closing
