Lesson Plan: Addition and Subtraction with 10

Subject: Mathematics Topic: Number, Money, and Measure Grade Level: First Level (Scottish Curriculum)

Desired Outcome: I can use addition, subtraction, multiplication, and division when solving problems, making the best use of the mental strategies and written skills I have developed.

Learning Objectives: 1. Understand the concept of addition and subtraction with 10. 2. Apply mental strategies and written skills to solve addition and subtraction problems involving numbers up to 10. 3. Develop fluency in using addition and subtraction with 10 to solve real-life problems.

Resources: - Whiteboard or blackboard - Markers or chalk - Number cards (0-10) - Counters or small objects - Worksheets (optional)

Introduction (10 minutes): 1. Begin the lesson by reviewing the concept of addition and subtraction. 2. Ask the students to recall what they know about addition and subtraction. 3. Introduce the concept of addition and subtraction with 10, explaining that we will focus on adding or subtracting numbers up to 10. 4. Write the following examples on the board: - Addition: 5 + 3 = ? - Subtraction: 8 - 2 = ? 5. Discuss the examples and ask the students to share their strategies for solving them.

Development (20 minutes): 1. Divide the class into pairs or small groups. 2. Distribute number cards (0-10) and counters or small objects to each group. 3. Instruct the students to take turns picking a number card and placing the corresponding number of counters on the table. 4. Ask the students to work together to solve addition and subtraction problems using the counters. - For addition: “If I have 5 counters and I add 3 more, how many do I have in total?” - For subtraction: “If I have 8 counters and I take away 2, how many do I have left?” 5. Encourage the students to use mental strategies and written skills to solve the problems. 6. Circulate around the classroom, providing support and guidance as needed.

Consolidation (15 minutes): 1. Bring the class back together and discuss the strategies used by different groups to solve the problems. 2. Write a few addition and subtraction problems on the board, involving numbers up to 10. 3. Ask individual students to come to the board and solve the problems using mental strategies and written skills. 4. Provide feedback and praise for correct answers and effective problem-solving strategies. 5. If time permits, distribute worksheets for additional practice or assign them as homework.

Conclusion (5 minutes): 1. Summarize the key points covered in the lesson, emphasizing the importance of using mental strategies and written skills in solving addition and subtraction problems. 2. Encourage the students to practice addition and subtraction with 10 in their daily lives, such as counting money or solving simple word problems. 3. Remind the students of the desired outcome: to use addition, subtraction, multiplication, and division when solving problems, making the best use of their mental strategies and written skills.

Note: The lesson plan can be adjusted based on the specific needs and abilities of the students.
