5th Grade Addition And Subtraction Of Fractions Lesson Plan (Math)

Topic: Adding and Subtracting Fractions with like Denominators

Objectives & Outcomes

• By the end of this lesson, students will be able to add and subtract fractions with like denominators.

Materials

• Fraction strips or other manipulatives for modeling fractions (optional)
• Whiteboard and markers
• Fraction strips or other manipulatives for modeling fractions (optional)

Warm-up

• Review what fractions are and their parts (numerator and denominator). Ask students to give examples of fractions they have seen before, such as half, third, and two-thirds.
• Show the students a fraction strip or set of manipulatives and have them construct a fraction using the parts shown (numerator = 1, denominator = 3).
• Ask the students to explain their reasoning for each step they take.

Direct Instruction

• Review the definition of a fraction as a part of a whole.
• Introduce the concept of a like denominator, which is when two or more fractions have the same denominator.
• Show the students more fraction strips or manipulatives and have them identify fractions with like denominators.
• Demonstrate how to add or subtract fractions with like denominators using the Addition and Subtraction of Like Fractions worksheet.
• Have the students work through a few examples using the worksheet or manipulatives to practice adding and subtracting fractions with like denominators.

Guided Practice

• Divide the class into pairs or small groups and give each group a set of fraction strips or manipulatives.
• Have the students work together to add or subtract fractions with like denominators using the Addition and Subtraction of Like Fractions worksheet.
• Monitor the students as they work and provide assistance as needed.

Independent Practice

• Provide the students with a set of fraction strips or manipulatives and a worksheet similar to the Addition and Subtraction of Like Fractions worksheet.
• Have the students work independently to add or subtract fractions with like denominators using the fraction strips or manipulatives.
• Monitor the students as they work and provide assistance as needed.

Closure

• Review the key steps for adding and subtracting fractions with like denominators using fraction strips or manipulatives.
• Ask the students to share any questions or challenges they encountered while practicing adding and subtracting fractions with like denominators.

Assessment

• Observe the students during the guided and independent practice to assess their understanding of adding and subtracting fractions with like denominators.
• Collect and review the students' completed worksheets to assess their ability to add and subtract fractions with like denominators.
