Lesson Plan: Number Sense for Grade 2

Subject: Mathematics
Topic: Number Sense
Duration: 30 minutes
Grade Level: 2

---

Objective

Students will develop a better understanding of number sense including counting, place value, comparing numbers, and basic operations through engaging activities and collaboration. By the end of the lesson, students should be able to:

1. Count forwards and backwards within 100.
2. Compare and order numbers up to 100.
3. Demonstrate an understanding of place value.
4. Perform basic addition and subtraction with sums and differences within 20.

• Number cards (0-100)
• Base ten blocks
• Worksheets for practice
• Homework sheets
• Pencils

Lesson Outline

Introduction (5 minutes)

1. Warm-up Activity:
   Start the class with a brief counting exercise. Have students count from 1 to 100 together, both forwards and backwards. This will engage them and reinforce sequencing of numbers.

2. Discussion:
   Ask students what they understand by the term "number sense." Encourage them to share their thoughts on counting and comparing numbers.

Guided Practice (15 minutes)

1. Place Value Activity:

   • Introduce base ten blocks and explain how they represent numbers.
   • Have students group the blocks to form numbers (e.g., 23 can be represented with 2 tens and 3 ones).
   • Invite students to share their numbers with the class.

2. Comparing Numbers:

   • Write several pairs of numbers on the board (e.g., 45 and 54).
   • Ask students to identify which number is larger and discuss reasoning.
   • Hand out number cards for a quick "greater than, less than, or equal to" game. Students will hold up cards to compare numbers.

3. Addition and Subtraction Practice:

   • Write simple addition and subtraction problems on the board (e.g., 7 + 5, 14 - 6).
   • Solve the problems together as a class, encouraging students to explain their thought processes.

Independent Practice (5 minutes)

• Hand out a worksheet with number sense questions that includes:
  • Counting exercises
  • Place value questions
  • Comparison problems
  • Simple addition and subtraction problems

Students will complete the worksheet independently.

Closing (5 minutes)

1. Review Key Concepts:
   Summarize the day's lesson by reviewing key concepts of number sense, place value, and comparison.

2. Question Session:
   Offer a few minutes for students to ask questions for clarification or further understanding about the day's lesson.

Homework

For homework, students will complete the following tasks:

1. Counting Practice:
   Count and write the numbers from 1 to 50.

2. Place Value:
   Draw a number using base ten blocks for a number of your choice between 10 and 50. Write down the number and what each block represents.

3. Comparison Problems:
   Compare the following pairs of numbers:

   • 23 and 32 (Answer: 23 < 32)
   • 47 and 40 (Answer: 47 > 40)

4. Addition and Subtraction:
   Solve the following problems:

   • 9 + 8 = ___ (Answer: 17)
   • 15 - 7 = ___ (Answer: 8)

Assessment

At the end of the week, students will be assessed on their understanding of number sense through a brief quiz that covers counting, place value, and simple operations.

---

Reflection

After the lesson, reflect on what worked well and what can be improved. Consider student engagement, understanding, and any areas of difficulty that may need revisiting in future lessons.
