Lesson Plan: Determine Whether Number Sentences Are True or False

Subject: Mathematics

Grade: 1

Duration: 30 Minutes

Topic: Determining the Truth of Number Sentences

---

Objective

Students will learn how to determine whether a number sentence is true or false. By the end of the lesson, students will be able to evaluate simple number sentences involving addition and subtraction.

Common Core Standards

• CCSS.MATH.CONTENT.1.OA.D.7: Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false.

---

Materials Needed

• Whiteboard and markers
• Number sentence cards (true and false)
• Worksheet for practice
• Markers or crayons for student use

---

Introduction (5 minutes)

• Begin with a brief discussion on what a number sentence is.
• Explain that a number sentence is like a math statement that can be either true or false.
• Introduce the concept of the equals sign (“=”) and explain that it shows balance between two sides.

Direct Instruction (10 minutes)

1. Explaining True vs. False:

   • Write a simple number sentence on the board: 2 + 2 = 4.
   • Ask students if this statement is true or false.
   • Confirm that it is true.
   • Write another number sentence: 3 + 1 = 5.
   • Discuss whether this number sentence is true or false and explain.

2. Demonstration:

   • Show several more examples on the board:
     • 5 - 2 = 3
     • 4 + 3 = 8
     • 6 - 6 = 0
   • For each, involve students in determining if it is true or false, asking them to explain their reasoning.

Guided Practice (10 minutes)

• Using number sentence cards, divide the class into small groups.
• Each group will receive a mix of true and false number sentences.
• Ask them to work together to evaluate each sentence and determine whether it's true or false.
• Walk around to provide support and guidance as needed.

Independent Practice (5 minutes)

• Hand out a worksheet with a mix of number sentences similar to those discussed in class.
• Students will circle "T" for True or "F" for False next to each sentence.
• Monitor students as they complete the worksheet and provide assistance where necessary.

Closure (5 minutes)

• Review the main points of the lesson by asking students what they learned about number sentences being true or false.
• Encourage students to practice by creating their own number sentences at home.

Reflection

At the end of the lesson, reflect on students' understanding of the true or false concepts through observation and their answers on the worksheet and homework. Adjust future lessons as needed based on this feedback.
