Introduction (10  15 minutes)

Review of Prerequisite Knowledge: The teacher will begin by revisiting the concept of threedimensional 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.

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.

RealWorld Applications: The teacher will stress the importance of understanding the volume of a prism in reallife situations, such as architecture, engineering, and even in everyday tasks like packing a suitcase or stacking boxes.

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 threedimensional object, and in the case of prisms, it can be calculated using a simple formula.

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?

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.

Interactive Online Activity: After watching the video and reading the material, students will be asked to complete an interactive online activity where they will have to calculate the volume of different prisms. The activity will allow students to apply the formula they've learned and practice their skills in a fun and engaging way. (Link to activity: https://www.mathplayground.com/measuringvolume.html)
InClass Activities (25  30 minutes)
Activity 1: "Prism Making Day"

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.

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.

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.

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.

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.

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: "RealWorld Prism Problems"

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

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

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.

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 problemsolving abilities.
By the end of these inclass activities, students should have a clear understanding of the volume of prisms and be able to apply this knowledge to solve problems in realworld contexts. The handson, collaborative nature of the activities will not only make learning fun but also enhance students' spatial reasoning and problemsolving skills.
Feedback (8  10 minutes)

Group Discussions: The teacher will facilitate a group discussion, where each group will share their solutions and the process they used to calculate the volume of their prisms in "Prism Making Day" activity. The teacher will encourage other groups to ask questions and provide feedback. The purpose of this discussion is to promote peer learning and to give students an opportunity to learn from each other's approaches.

Connection to Theory: The teacher will then help students to connect the solutions found in the group activities with the theoretical knowledge they gained from the video and reading materials. They will highlight how the formula for the volume of a prism (base area x height) was applied practically in the creation of prisms and the solution of realworld problems. This step will reinforce the understanding of the concept and its application.

Reflection on Learning: The teacher will then ask students to take a moment to reflect on their learning. They will be asked to consider the following questions:
a. What was the most important concept learned today? This question will help students identify the key learning points from the lesson, ensuring that they have a clear understanding of the volume of prisms.
b. Which questions have not yet been answered? By identifying any remaining doubts or questions, this reflection will allow students to articulate what they still need to learn. The teacher can then address these questions in the next lesson or provide additional resources for students to explore independently.
c. How can you apply what you learned today in real life? This question will prompt students to consider the practical applications of their learning, reinforcing the idea that math is not just an abstract concept but a tool that can be used in everyday life.

Assessment of Learning: Based on the group discussions and the students' reflections, the teacher will assess the students' understanding of the volume of prisms and their ability to apply this knowledge in solving problems. This assessment will guide the teacher in determining whether the learning objectives have been met or if any further intervention is required.
