Mathematics Lesson Plan

Grade Level:

3rd Grade

Duration:

30 Minutes

Learning Objectives:

• Students will be able to understand and apply the concept of addition and subtraction within 100.
• Students will demonstrate problem-solving skills by working through word problems.

Materials Needed:

• Whiteboard and markers
• Worksheets with addition and subtraction problems
• Counters or blocks for hands-on practice
• Timer

Lesson Outline:

1. Introduction (5 minutes)

• Begin with a brief review of addition and subtraction.
• Ask students to share strategies they use for adding and subtracting numbers.
• Introduce the day's focus: solving multi-step word problems that involve addition and subtraction.

2. Direct Instruction (10 minutes)

• Explain the process of solving a word problem:

  1. Read the problem carefully.
  2. Identify the numbers involved.
  3. Determine what is being asked.
  4. Decide whether to add or subtract.
  5. Solve the problem and check your work.

• Write a sample word problem on the board. For example: "Tom has 47 apples and picks 26 more. How many apples does he have now?"

• Solve the problem step-by-step with the students, emphasizing vocabulary and operations used.

3. Guided Practice (10 minutes)

• Distribute the worksheets that contain five word problems for students to work on.
• Allow students to work in pairs to encourage collaboration.
• While students work, circulate around the room to provide support and answer questions.

4. Independent Practice (5 minutes)

• Give students a new word problem to solve individually, such as: "Sara has 78 pencils. She gave 20 to her friend. How many pencils does she have now?"
• Ask students to show their work as they solve the problem.

5. Conclusion and Reflection (5 minutes)

• Gather the students for a brief discussion on what they learned.
• Ask a few students to share their answers to the final problem and explain their thought process.
• Review any common mistakes and clarify any misunderstandings.
• Wrap up by highlighting the importance of understanding the context of word problems for effective problem-solving.

Assessment:

• Collect the worksheets for evaluation.
• Observe student participation during pair and class discussions.

Homework:

• Assign a simple worksheet with three additional word problems for students to complete at home.

Standards Addressed:

• [CCSS.MATH.CONTENT.3.OA.A.1]: Interpret products of whole numbers.
• [CCSS.MATH.CONTENT.3.NBT.A.2]: Fluently add and subtract within 100.
