Lesson Plan for Reception - Mathematics - Simple Addition and Subtraction

### Lesson Plan: Simple Addition and Subtraction #### Grade Level: Reception #### Duration: 45 minutes #### Topic: Simple Addition and Subtraction #### Objective: - Students will learn the basic concepts of addition and subtraction. - Students will be able to perform simple addition and subtraction using numbers up to 10. - Students will understand and use the vocabulary associated with addition and subtraction (e.g., add, subtract, equals, more, less). #### Materials Needed: - Number flashcards (1-10) - Small counting objects (e.g., buttons, blocks, counters) - Whiteboard and markers - Worksheets with addition and subtraction problems - Visual aids (e.g., number line) #### Lesson Outline: **1. Introduction (5 minutes)** - Greet the students and introduce the topic of the lesson: "Today, we are going to learn about adding and taking away numbers." - Show the number flashcards and count together from 1 to 10 to refresh number recognition. **2. Whole Group Instruction (10 minutes)** - **Addition:** - Use counting objects to demonstrate an addition problem. E.g., "If we have 2 buttons and we add 3 more buttons, how many buttons do we have in total?" - Show the equation on the whiteboard: 2 + 3 = 5. - Emphasise the vocabulary: "Add" means to bring more, and "equals" means the total. - **Subtraction:** - Use counting objects to demonstrate a subtraction problem. E.g., "If we have 5 buttons and we take away 2 buttons, how many buttons are left?" - Show the equation on the whiteboard: 5 - 2 = 3. - Emphasise the vocabulary: "Subtract" means to take away, and "equals" means what is left. **3. Guided Practice (10 minutes)** - Hand out small counting objects to each student. - Give simple addition and subtraction problems for the students to solve with their counting objects. E.g., "Can you show me 4 + 2 using your counters? Now, can you show me 6 - 1?" - Walk around and assist where needed. Reinforce the use of mathematical vocabulary. **4. Independent Activity (10 minutes)** - Provide each student with a worksheet containing simple addition and subtraction problems (numbers up to 10). - Instruct students to use their counting objects to help solve the problems if they need to. **5. Review and Closure (5 minutes)** - Gather the students on the carpet and review a few problems from the worksheet as a group. - Ask questions about the problems: "How did we solve 3 + 2? What does subtract mean again?" - Praise their hard work and encourage them to practise adding and taking away numbers at home with their parents. **6. Extension (for Early Finishers)** - Provide extra worksheets with slightly more challenging problems or encourage them to create their own addition and subtraction stories. **Assessment:** - Observe students during guided practice to see if they understand the concepts of addition and subtraction. - Review completed worksheets to assess individual understanding. - Ask questions during the review to gauge comprehension and correct any misunderstandings. ### Notes for Teachers: - Be patient and provide lots of positive reinforcement. - Use a variety of examples to ensure all students grasp the concepts. - Adapt the pace of the lesson based on the students’ responses and engagement.
