Learning Intention: To understand the concept of fractions and be able to add and subtract fractions with like denominators.
Success Criteria: 1. Students will be able to identify the numerator and denominator of a fraction. 2. Students will be able to add and subtract fractions with like denominators. 3. Students will be able to solve word problems involving fractions.
Guided Practice: 1. Begin the lesson by reviewing the concept of fractions. Ask students to define a fraction and identify the numerator and denominator of a given fraction. 2. Provide examples of fractions with like denominators and guide students through the process of adding and subtracting them. Use visual aids, such as fraction bars or circles, to help students visualize the operations. 3. Model the steps involved in solving word problems involving fractions. Emphasize the importance of understanding the context and identifying the operation required (addition or subtraction).
Independent Practice: 1. Distribute a worksheet with a variety of fraction addition and subtraction problems. Include word problems to assess students’ ability to apply the concept in real-life situations. 2. Encourage students to show their work and explain their reasoning for each problem. 3. Provide cues and prompts to support independent practice: - What is the denominator of the fractions given? - Are the denominators the same? If not, what do you need to do to make them the same? - Can you simplify the fraction before adding or subtracting? - What operation (addition or subtraction) should you use to solve the word problem? - Can you represent the problem using a visual aid, such as a diagram or fraction model?
Question: 1. What is the first step in adding or subtracting fractions with like denominators? 2. How can you simplify a fraction before performing addition or subtraction? 3. How can you represent a word problem involving fractions using a visual aid? 4. Can you explain the difference between the numerator and denominator of a fraction? 5. Can you solve the following word problem: “John had 3/4 of a pizza and ate 1/4 of it. How much pizza does he have left?”
Cues and Prompts: - Remember to find a common denominator when adding or subtracting fractions. - Think about whether the fraction can be simplified before performing the operation. - Use visual aids, such as fraction bars or circles, to help you understand and solve word problems. - Make sure to clearly label the numerator and denominator when representing a fraction.
