Introduction: The lesson will begin with a brief introduction to oxidation number, which is a measure of the number of electrons that an atom has gained or lost in a chemical reaction. The teacher will explain that oxidation number is an important concept in chemistry, as it helps to predict the reactivity of elements and the formation of chemical compounds.

Lesson Outline: 1. Definition of oxidation number 2. Rules for assigning oxidation numbers 3. Examples of assigning oxidation numbers 4. Applications of oxidation numbers in predicting chemical reactions

Questioning: The teacher will ask the following questions to assess students’ understanding of the topic: 1. What is oxidation number? 2. How do you assign oxidation numbers to elements in a compound? 3. What is the significance of oxidation numbers in predicting chemical reactions?

Assessment: The teacher will assess students’ understanding of the topic through a worksheet that includes questions on assigning oxidation numbers and predicting chemical reactions based on oxidation numbers.

Differentiation: To cater to the different learning needs of students, the teacher will provide additional resources such as videos and interactive quizzes to reinforce the concept of oxidation number.

Plenary: The lesson will conclude with a plenary session where students will be asked to summarize the key points of the lesson and share their understanding of oxidation number.
