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	Details
1	Introduction	5 minutes	Briefly introduce rational numbers and their relevance in everyday life. Provide examples.
2	Definition and Forms	10 minutes	Discuss the definition of rational numbers. Show examples in fraction and decimal forms. Engage students by asking for more examples.
3	Operations Overview	5 minutes	Introduce addition and subtraction of rational numbers. Use simple examples to illustrate concepts.
4	Guided Practice	5 minutes	Distribute worksheets. Work through the first problem as a class. Provide support as students work on the next few problems independently or in pairs.
5	Independent Practice	5 minutes	Allow students to complete remaining problems on their own. Circulate to provide assistance as needed.
6	Review and Closure	5 minutes	Go over some solutions together without calling on students to present. Ensure understanding by answering any remaining questions.

Homework

• Assign students to complete a worksheet on rational numbers focusing on identifying and performing operations with rational numbers.
• Collect the homework the next day without requiring students to present it in front of the class.

Additional Notes

• Encourage student participation by asking questions and prompting discussions throughout the lesson.
• Ensure that all students are included in the practice activities, catering to different learning paces.
• Adjust the complexity of problems based on the students’ understanding during guided practice.
