Objectives (5 - 7 minutes)

1. Understand the concept of Volume in Spatial Geometry: Students will be able to define what volume is in the context of spatial geometry. They will understand that volume is the amount of space occupied by a three-dimensional figure, such as a prism.

2. Learn the formula for calculating the Volume of a Prism: Students will be introduced to the formula for finding the volume of a prism, which is the product of the prism's base area and its height. They will understand how the concepts of area and height are applied to find the volume.

3. Apply the Volume formula to solve problems: Students will be able to apply the learned formula to solve real-world problems involving prisms. They will learn to identify the relevant dimensions of a prism, i.e., the height and the base area, and use these to calculate the volume.

Secondary Objectives:

• Develop problem-solving skills: Through the application of the volume formula in various problem scenarios, students will enhance their problem-solving abilities.
• Enhance spatial reasoning: The study of spatial geometry, including the calculation of volumes, will help students improve their spatial reasoning skills.

Introduction (10 - 15 minutes)

1. Review of Prerequisite Knowledge: The teacher will begin by revisiting the concept of three-dimensional shapes, specifically prisms, which have already been covered in previous lessons. The students will be asked to recall the characteristics of prisms and the methods for calculating their areas.

2. Problem Situations: The teacher will then present two problem situations that will serve as the basis for the development of the theory. The first problem could involve calculating the amount of water a rectangular fish tank can hold. The second problem could be about finding the volume of a package that a mailman needs to deliver.

3. Real-World Applications: The teacher will stress the importance of understanding the volume of a prism in real-life situations, such as architecture, engineering, and even in everyday tasks like packing a suitcase or stacking boxes.

4. Introduction of the Topic: The teacher will introduce the topic of the day - the volume of prisms. They will explain that volume is the amount of space occupied by a three-dimensional object, and in the case of prisms, it can be calculated using a simple formula.

5. Curiosity and Engagement: To grab the students' attention, the teacher will share two interesting facts related to the topic:

   • Fact 1: The Great Pyramid of Giza, one of the wonders of the ancient world, is actually a type of prism called a square pyramid. The volume of the pyramid is estimated to be about 2,500,000 cubic meters!
   • Fact 2: The world's largest building by volume is the Boeing Everett Factory in Washington, USA. It is so huge that it has its own weather inside! Can you imagine how much space it occupies?

6. Connection to Everyday Life: The teacher will emphasize that understanding the volume of prisms is not only important for passing exams but also for many practical purposes in everyday life. For instance, it can help us determine the amount of liquid a container can hold, the space required to store things, or even the capacity of a building.

In-Class Activities (25 - 30 minutes)

Activity 1: "Prism Making Day"

1. Group Formation: The teacher will divide the class into groups of four or five students each. The groups will be formed in a way that encourages diversity and ensures that each group has a mix of high, average, and low performing students.

2. Materials Distribution: The teacher will distribute construction paper, scissors, and glue to each group. The construction paper will be of various colors to make the activity more engaging and appealing.

3. Task Explanation: The teacher will explain that the students will create prisms using the construction paper. They will then be asked to calculate the volume of their prisms. The groups will be given a sample prism to use as a guide, but they will have the flexibility to choose the dimensions of their prisms.

4. Prism Creation: The students will work in their groups to create their prisms, using their understanding of prisms and the formula for volume to determine the dimensions of their prisms.

5. Volume Calculation: Once the prisms are ready, the groups will calculate the volume of their prisms using the formula: Volume = (Base Area) x Height. The teacher will walk around the classroom, providing support and guidance as needed.

6. Display and Reflection: Finally, each group will present their prisms to the class, explaining their thought process and the steps they took to calculate the volume. The teacher will facilitate a brief discussion, encouraging students to ask questions and provide constructive feedback.

Activity 2: "Real-World Prism Problems"

1. Task Explanation: Following the "Prism Making Day" activity, the teacher will assign another task to the students. They will be given a set of real-world problems involving prisms and asked to solve them using the formula for volume.

2. Problem Solving: The students will work individually on these problems, using their understanding of volume and the formula for prisms to arrive at solutions.

3. Group Discussion: After a given period of time, the students will be asked to discuss their solutions in their groups. This will provide an opportunity for them to learn from each other, clarify any doubts, and improve their understanding of the topic.

4. Solution Sharing: Finally, the teacher will ask a few students to share their solutions with the class, fostering peer learning and boosting students' confidence in their problem-solving abilities.

By the end of these in-class activities, students should have a clear understanding of the volume of prisms and be able to apply this knowledge to solve problems in real-world contexts. The hands-on, collaborative nature of the activities will not only make learning fun but also enhance students' spatial reasoning and problem-solving skills.
