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 Structure

Step Number	Step Title	Length (Minutes)	Details
1	Introduction to Inverse Operations	5	Explain what inverse operations are, providing examples of addition and subtraction. Introduce the terminology.
2	Guided Practice	10	Work through addition and subtraction problems as a class. Demonstrate how to apply inverse operations using examples on the whiteboard. Use counters for visual representation.
3	Independent Practice	10	Distribute worksheets with addition and subtraction problems. Allow students to work independently on these problems while providing support as needed.
4	Review and Discuss	3	Review the answers to the worksheet in an open discussion. Encourage students to share their strategies without needing any formal presentations.
5	Conclusion and Homework	2	Summarise key concepts learned during the lesson. Assign homework that reinforces the use of inverse operations with a variety of addition and subtraction tasks. Check understanding by collecting worksheets at the end of class.

Homework

• Complete a worksheet with 10 problems involving addition and subtraction that reinforces the concept of inverse operations, to be submitted in the next class. No presentations required; just a simple submission for feedback.

Assessment

• Informal assessment through observation during guided and independent practice.
• Homework will be checked to ensure understanding without requiring presentations.

Notes for Teacher

• Be prepared to adjust the pace based on students' understanding of concepts.
• Utilize manipulatives to cater to different learning styles and provide visual aids for students who may need additional support.
