Lesson Plan on Developing Number Sense

Lesson Title:Developing Number Sense

Lesson Objective: Students will understand the concept of number sense and be able to apply it to solve problems involving place value, addition, subtraction, multiplication, and division.

Materials:

Chart paper and markers

Base ten blocks or other manipulatives

Worksheets with number sense problems

Introduction (5 minutes):

Begin by asking the students if they know what number sense is. Allow them to share their ideas and write them on the board.

Next, explain that number sense is the ability to understand and work with numbers in a flexible and efficient way. It is the foundation for understanding and solving mathematical problems involving place value, addition, subtraction, multiplication, and division.

Direct Instruction (15 minutes):

Using manipulatives (such as base ten blocks), demonstrate how to use number sense to solve problems involving place value, addition, subtraction, multiplication, and division. For example, use base ten blocks to show how to break down a number into its place value components and then use that to solve a subtraction problem.

Next, have the students work in pairs to practice using number sense with manipulatives.

As they work, walk around to check for understanding and provide assistance as needed.

Guided Practice (15 minutes):

Provide the students with worksheets containing number sense problems.

Have them work in pairs to complete the worksheets, with one student solving the problem and the other student checking the work.

Monitor the student progress and provide assistance as needed.

Independent Practice (10 minutes):

Give the students more worksheets with number sense problems and have them work independently.

Circulate around the room to check for understanding and provide assistance as needed.

Closure (5 minutes):

Have students share one way they used number sense to solve a problem today.

Review the main concept of number sense and remind the students that number sense is the ability to understand and work with numbers in a flexible and efficient way, and it is the foundation for understanding and solving mathematical problems involving place value, addition, subtraction, multiplication, and division.

Assessment: Observe the students during independent practice and check their worksheets for accuracy.

Extension:

Have the students create their own number sense problems and have them share it with the class.

Allow them to play math games that involve number sense, such as “Number Sense Match”

Note:

Remember to differentiate instruction to meet the needs of all the students in your class.

Encourage students to use number sense in real-life situations, such as shopping and budgeting.

Overall, the goal of this lesson is to introduce the concept of number sense and provide students with hands-on practice using it to solve problems involving place value, addition, subtraction, multiplication, and division. Through the use of manipulatives, worksheets, and interactive activities, students will develop a better understanding of number sense and be able to apply it in various situations.
