Grade 4 Math Lesson on Addition With Regrouping and Word Problems. Uses Manipulatives and Differentiated Instruction. Duration: 45 Minutes.

Lesson Plan: Addition (Grade 4)

Subject: Mathematics Topic: Addition Grade Level: 4th Grade Duration: 45 minutes

Learning Objectives:

1. Students will be able to add two-digit numbers with regrouping.
2. Students will be able to solve word problems involving addition.
3. Students will be able to apply addition strategies to real-life situations.

Materials:

• Whiteboard or blackboard
• Markers or chalk
• Addition flashcards
• Worksheets with addition problems
• Word problem cards
• Manipulatives (e.g., base-ten blocks, counters)

Procedure:

Introduction (10 minutes):

1. Begin the lesson by reviewing the concept of addition and its importance in everyday life.
2. Ask students to share examples of situations where addition is used (e.g., buying groceries, calculating time, sharing items).
3. Explain that today's lesson will focus on adding two-digit numbers with regrouping and solving word problems using addition.

Instruction (15 minutes):

1. Introduce the concept of regrouping in addition by writing a two-digit addition problem on the board (e.g., 34 + 28).
2. Model the regrouping process step-by-step, explaining how to carry over the tens place value.
3. Use manipulatives (e.g., base-ten blocks) to demonstrate the regrouping process visually.
4. Provide additional examples on the board, allowing students to practice regrouping with your guidance.
5. Use flashcards to practice adding two-digit numbers without regrouping.

Guided Practice (10 minutes):

1. Distribute worksheets with addition problems to each student.
2. Assign students to work in pairs or small groups.
3. Circulate the classroom, providing support and guidance as needed.
4. Encourage students to use manipulatives or drawings to help them solve the problems.
5. After completing the worksheets, review the answers as a class, discussing any challenges or misconceptions.

Differentiated Instruction (10 minutes):

1. Divide the class into three groups based on their readiness levels: below grade level, on grade level, and above grade level.
2. Provide additional support to the below-grade-level group by working with them in a small group setting, using manipulatives and providing step-by-step guidance.
3. Assign the on-grade-level group to complete word problem cards, which require them to apply addition strategies to real-life situations.
4. Challenge the above-grade-level group with more complex addition problems or multi-step word problems.

Conclusion (5 minutes):

1. Review the key concepts covered in the lesson, including regrouping in addition and solving word problems using addition.
2. Ask students to share any new strategies or insights they gained during the lesson.
3. Provide positive feedback and reinforce the importance of practicing addition skills in everyday life.

Assessment:

1. Monitor students' progress during the guided practice and differentiated instruction activities.
2. Collect and review the completed worksheets and word problem cards to assess individual understanding.
3. Use informal observation and questioning to assess students' ability to apply addition strategies and solve word problems accurately.
4. Provide feedback and offer additional support or enrichment activities as needed.
