Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson Plan: Addition and Subtraction Word Problems

Topic

Use addition and subtraction to solve word problems within 20 by using concrete objects, drawings, and equations with a symbol for the unknown number.

Objectives

• Students will be able to solve addition and subtraction word problems within 20.
• Students will demonstrate understanding of "add to," "take from," "put together/take apart," and "compare quantities."
• Students will apply properties of operations as strategies to solve problems.

Grade/Age Group

Year/Grade 1

Subject

Mathematics

Materials

• Concrete objects (e.g., counters, blocks)
• Whiteboard and markers
• Worksheets with word problems
• Drawing paper and crayons
• A chart for displaying addition and subtraction equations

Class Size

16 students

National Curriculum Alignment

• AL 1: Use addition and subtraction to solve word problems within 20.

  • a. Add to with change unknown.
  • b. Take from with change unknown.
  • c. Put together/take apart with addend unknown.
  • d. Compare quantities with difference unknown, bigger unknown, and smaller unknown.

• AL 3: Apply properties of operations as strategies to add.

Lesson Length

40 minutes

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction	5 min	Briefly introduce the topic and objectives. Explain importance of solving word problems in real-life contexts.
2	Concrete Object Activity	10 min	Use counters to demonstrate "add to" and "take from" concepts. Provide examples for students to practice.
3	Word Problem Worksheets	10 min	Distribute worksheets with various word problems. Students solve problems individually or in pairs using drawings and equations.
4	Group Discussion	5 min	Discuss different ways to solve the word problems. Encourage sharing of strategies and solutions.
5	Application of Properties	5 min	Introduce properties of operations. Model how properties can simplify solving addition and subtraction problems.
6	Guided Practice	5 min	Provide additional problems for students to practice in pairs, using both concrete objects and drawings.
7	Closing	5 min	Summarize key points. Assign homework with word problems. Remind students to check their work.

Homework

• Assign a worksheet with additional word problems for students to solve at home. Ensure students understand they will not be required to present their homework in front of the class.

Assessment

• Monitor student participation and understanding during activities.
• Review completed worksheets for accuracy and understanding of concepts.
• Provide feedback individually after homework submission.

Additional Notes

• Be mindful of diverse learning needs and adjust support as necessary.
• Encourage team collaboration and discussion to enhance problem-solving skills.
