Free Add And Subtract Fractions Lesson Plan for 4th Grade Students

Topic: Add and Subtract fractions

Objectives & Outcomes

• Students will be able to add and subtract fractions with different denominators and numerators.

Materials

• Fraction strips or equivalent manipulatives (optional)
• Whiteboard and markers
• Handouts with fraction problems for students to solve

Warm-up

• Review what fractions are and what they represent.
• Ask students to give examples of fractions they have seen in everyday life, such as half, a third, and a quarter.
• Ask students to share their experiences adding and subtracting fractions.

Direct Instruction

• Introduce the concept of adding fractions with different denominators.
• Show students an example of a fraction with a different denominator, such as 1/2 and 3/4, and ask them to try to picture what the resulting fraction would look like.
• Explain that to add the fractions, we need to find a common denominator: the denominator that is the same for both fractions.
• Using the common denominator, we can then add the numerators: the top numbers.
• Show students how to write the resulting fraction, with the common denominator, and add the numerators.
• Repeat this process with more examples, asking students to try to visualize the resulting fraction before writing it down.

Guided Practice

• Provide students with a worksheet with fraction problems to solve, with different denominators.
• Go through the problems with the class, starting with easy problems and building up to more challenging problems.
• As students work, circulate the room to provide support and guidance as needed.

Independent Practice

• Provide students with a worksheet with mixed fraction problems to solve, with different denominators.
• Have students work on the problems individually or in small groups.
• Encourage students to check their work and correct any errors they find.

Closure

• Review the steps for adding and subtracting fractions with the same denominator.
• Ask students to share any questions or problems they had while working on the project.

Assessment

• Observe students during independent practice to assess their understanding of adding and subtracting fractions with the same denominator.
• Collect and review their completed projects to assess their ability to add and subtract fractions with the same denominator.
