Lesson Plan: Number Sense to 20

Subject: Mathematics

Grade: 1

Duration: 30 Minutes

Topic: Number Sense to 20

---

Objectives

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

1. Recognize and write numbers from 1 to 20.
2. Count objects up to 20.
3. Compare quantities using the terms "greater than," "less than," and "equal to."
4. Solve simple addition and subtraction problems within 20.

Materials Needed

• Number cards (1-20)
• Counting manipulatives (e.g., blocks, counting bears)
• Whiteboard and markers
• Worksheets for practice
• Homework handouts

---

Introduction (5 Minutes)

1. Greeting: Welcome students and take attendance.
2. Warm-Up Activity:
   • Count aloud from 1 to 20 as a class.
   • Use number cards to flash numbers and have students repeat them.
3. Objective Sharing: Explain what students will learn today and why number sense is important.

Direct Instruction (10 Minutes)

1. Number Recognition:

   • Show number cards one at a time.
   • Discuss how each number corresponds to a quantity.

2. Counting Objects:

   • Group students into pairs.
   • Give each pair a set of counting manipulatives and ask them to count out loud to 20 using the manipulatives.

3. Comparison of Quantities:

   • Use two different sets of objects (e.g., 5 blocks and 8 blocks).
   • Ask students which set has more and which has less, discussing the terms greater than, less than, and equal to.

---

Guided Practice (10 Minutes)

1. Number Matching Game:

   • Spread number cards on the floor.
   • Students take turns picking manipulatives and matching them to the corresponding number card.

2. Addition and Subtraction Practice:

   • On the whiteboard, write a simple addition problem (e.g., 3 + 2 = ?).
   • Solve the problem together as a class, asking students to raise their hands when they have the answer.
   • Repeat with a subtraction problem (e.g., 6 - 2 = ?).

---

Independent Practice (3 Minutes)

• Hand out a short worksheet that includes:
  1. Number Writing: Write the numbers from 1 to 10.
  2. Counting: Draw five stars, then count and write how many there are.
  3. Simple Problems: Solve 3 + 1 = ? and 5 - 1 = ?.

---

Closure (2 Minutes)

1. Review: Ask students to volunteer some numbers they learned today.
2. Recap: Highlight the importance of number sense and how we use numbers every day.
