Lesson Plan for Year 1 - Mathematics - Basic Addition and Subtraction

### Lesson Plan: Basic Addition and Subtraction **Class:** Year 1 **Subject:** Mathematics **Topic:** Basic Addition and Subtraction **Duration:** 60 minutes #### Learning Objectives: 1. Students will understand the concepts of addition and subtraction. 2. Students will be able to solve simple addition and subtraction problems with numbers up to 10. 3. Students will improve their number sense and ability to count. #### Materials Needed: - Whiteboard and markers - Number cards (0-10) - Counters (e.g., small blocks, buttons, or beans) - Addition and subtraction worksheets - Storybooks involving addition and subtraction (optional) - Interactive board or projector (optional) #### Introduction (10 minutes): 1. **Greeting and Warm-Up:** Start with a fun counting song to get students engaged. For example, "Ten Little Monkeys." 2. **Introduction to Topic:** Briefly explain that today we will be learning about addition (putting things together) and subtraction (taking things away). #### Direct Instruction (15 minutes): 1. **Addition:** - Write an addition problem on the board (e.g., 3 + 2). - Use counters to visually demonstrate the problem. Show how three counters added to two counters make five counters. - Repeat with a few more examples, encouraging students to count the total aloud with you. 2. **Subtraction:** - Write a subtraction problem on the board (e.g., 5 - 2). - Use counters to demonstrate the concept. Show five counters, take away two, and count how many are left. - Repeat with a few more examples, encourage students to count how many are left aloud with you. #### Guided Practice (15 minutes): 1. Distribute number cards and counters to small student groups. 2. **Addition Activity:** - Call out an addition problem (e.g., 4 + 3). - Have students use their counters to solve the problem and show their answers. 3. **Subtraction Activity:** - Call out a subtraction problem (e.g., 7 - 2). - Have students use their counters to solve the problem and show their answers. #### Independent Practice (10 minutes): 1. Distribute addition and subtraction worksheets. 2. Instruct students to complete the problems on their own. 3. Circulate around the room to provide assistance as needed. #### Closing (10 minutes): 1. **Review and Reinforcement:** - Gather students on the carpet or in a circle. - Review some of the problems from the worksheets, discussing how students arrived at their answers. - Reinforce key concepts by asking questions like "What does addition mean?" and "What does subtraction mean?" 2. **Interactive Game (if time permits):** - Play a simple addition and subtraction game such as ‘Addition Bowling’ where students knock down numbered pins and add or subtract the numbers to find a total. #### Assessment: - Observe student participation during guided practice. - Review completed worksheets to assess individual understanding. - Conduct quick, informal one-on-one assessments if necessary. #### Homework (optional): - Assign a simple worksheet with additional addition and subtraction problems for further practice at home. #### Differentiation: - Provide additional support for students struggling with the concepts by working with them in small groups or one-on-one. - Challenge advanced students with higher-number addition and subtraction problems or introduce the concept of “number bonds” as an extended activity. #### Reflection: - After the lesson, reflect on what went well and what could be improved. - Note any students who may need extra help or advanced activities in future lessons. --- This plan should be adjustable to fit the specific needs and dynamics of your classroom, providing a structured yet flexible approach to teaching basic addition and subtraction.
