Mathematics Lesson Plan: Addition and Subtraction Real-World Problems

Grade Level

• Year 1 (Grade 1)

Duration

• 50 Minutes

Lesson Topic

• MA.1.AR.1.2: Solve addition and subtraction real-world problems using objects, drawings, or equations to represent the problem.

Objectives

By the end of this lesson, students will be able to:

1. Understand how to apply addition and subtraction to real-world situations.
2. Represent problems using objects, drawings, or equations.
3. Solve word problems involving addition and subtraction.

Materials Needed

• Counting objects (counters, blocks, or any small items)
• Whiteboard and markers
• Paper and crayons
• Homework sheets (attached at the end of the lesson)
• Example word problem cards

Lesson Outline

Introduction (10 minutes)

• Begin the lesson with a short discussion on addition and subtraction.
• Ask students to share examples of when they use these skills in real life (e.g., counting toys, sharing snacks).
• Introduce the learning objective: solving real-world problems using addition and subtraction.

Direct Instruction (15 minutes)

• Present a few simple word problems on the whiteboard.

• Example Problem: "Anna has 3 apples. She picks 2 more apples from the tree. How many apples does she have now?"

  • Break down the problem together:
    1. Identify the numbers in the problem.
    2. Ask students what operation (addition or subtraction) to use.
    3. Solve the problem as a class using counting objects.

• Explain how to represent these problems using drawings or equations. Show an equation for the example problem: 3 + 2 = 5.

Guided Practice (15 minutes)

• Provide each student with a set of word problem cards.
• Students will work in pairs to solve the problems using objects or drawings.
• Walk around the classroom to assist and encourage students to discuss their thought processes with their partners.

Independent Practice (5 minutes)

• Distribute a worksheet containing a few addition and subtraction word problems.
• Students will solve these problems on their own using drawings or equations.

Closure (5 minutes)

• Bring the class back together and ask a few students to share their solutions with the class.
• Discuss different ways to solve the problems.
• Reinforce the importance of addition and subtraction in everyday life.

Homework

Provide students with the following tasks to complete at home:

Homework Sheet

1. David has 4 toy cars. His friend gives him 3 more cars. How many cars does David have now?
   Answer: 4 + 3 = 7 toy cars.

2. Lisa has 10 candies. She eats 2 of them. How many candies does she have left?
   Answer: 10 - 2 = 8 candies.

3. There are 5 birds on a tree and 3 more birds come to join them. How many birds are there in total?
   Answer: 5 + 3 = 8 birds.

Optional Activity

• Draw a picture of your favorite real-world problem involving addition or subtraction, and write an equation to match your drawing.

Assessment

• Monitor students during guided practice and independent work.
• Review completed homework sheets to assess understanding.

Reflection

• After the lesson, reflect on what strategies worked well and which concepts need more reinforcement in future lessons.

This lesson plan will help engage Grade 1 students with practical applications of addition and subtraction, reinforcing their mathematical understanding through real-world scenarios.
