# Introduction (10 - 15 minutes)

• The teacher will begin by reminding the students of the basic geometric concepts they have already learned, such as the properties of triangles, quadrilaterals, and circles. This review is important as it will serve as a foundation for the new concepts of congruence and similarity. The teacher may use visual aids or quick problem-solving exercises to refresh the students' memory. (3 - 5 minutes)

• The teacher will then present two problem situations that will serve as starters for the development of the theory. For instance, the teacher could ask:

1. "If two triangles have the same shape and size, how can we prove that they are congruent?"
2. "If two squares have the same shape but different sizes, what concept of geometry can we use to describe their relationship?" These questions will stimulate the students' curiosity and prepare them for the new concepts. (3 - 4 minutes)
• The teacher will contextualize the importance of the subject by discussing its real-world applications. The teacher could mention how architects use the concept of similarity to design buildings, or how engineers rely on the concept of congruence to build bridges and roads. The teacher could also talk about how these concepts are used in art and design, such as in creating patterns and mosaics. By linking the concepts of congruence and similarity to real-world contexts, the teacher will help the students understand the relevance and practicality of what they are learning. (2 - 3 minutes)

• To grab the students' attention and make the introduction more engaging, the teacher could share two interesting facts or stories related to the subject. For instance, the teacher could share that the ancient Egyptians used the concept of similarity in their pyramid designs, or that the concept of congruence is fundamental in the field of computer graphics, where it is used to create 3D models and animations. The teacher could also show a short video clip or a slideshow with fun, visually appealing examples of congruent and similar figures, such as a series of Russian dolls. (2 - 3 minutes)

By the end of this stage, the students should have a clear understanding of what they will be learning, why it is important, and how it can be applied in real-world contexts. They should also be curious and excited to explore the topic further.

# Development (20 - 25 minutes)

• Activity 1: "Congruence and Similarity Matching Game" (8 - 10 minutes)

1. The teacher prepares a set of cards, each featuring a two-dimensional figure. In pairs, the figures on one card are either congruent or similar to those on another card. Each pair of cards features a different figure or pair of figures.

2. The teacher distributes the cards among the students and instructs them to match the cards into pairs of congruent or similar figures.

3. After all the students have completed the task, the teacher asks them to explain how they determined which figures were congruent and which were similar. This encourages the students to articulate their understanding of these concepts.

• Activity 2: "Build Your Own City" (10 - 12 minutes)

1. The teacher divides the students into small groups and provides each group with a large sheet of paper, colored pencils, and a set of pre-cut geometric figures of varying sizes.

2. The task is for each group to create a cityscape using the geometric figures, while ensuring that congruent figures are positioned identically and similar figures are positioned with the same proportions. For example, a group may use congruent triangles to create a row of buildings, and similar rectangles of various sizes to create streets.

3. As the students work, the teacher moves around the room, observing the groups and offering guidance as needed. This allows the teacher to assess the students' understanding of the concepts and their ability to apply them in a practical context.

4. Once the groups have finished, each group presents their cityscape to the class, explaining which figures are congruent and which are similar, and justifying their choices. This encourages the students to communicate their understanding of the concepts and their reasoning behind their city design.

5. The cityscapes can be displayed in the classroom, serving as a visual reminder of the concepts of congruence and similarity, and as a source of inspiration for further discussions and activities.

• Activity 3: "Shape Transformation Relay" (5 - 7 minutes)

1. The teacher divides the students into teams and sets up a relay race. At one end of the room, there is a table with a set of large, pre-cut geometric figures. At the other end of the room, there is an empty table.

2. The first student from each team runs to the table, picks up a figure, and runs back to their team, where the next student is waiting. The first student then explains whether the figure is congruent or similar to the corresponding figure already on their team's table. If it is, they place it on the table; if not, they put it back and return to the line.

3. This continues until one team has correctly identified and placed all their figures, making them the winners of the relay race.

4. This activity reinforces the students' understanding of congruence and similarity, and it also adds a fun, competitive element to the lesson, increasing the students' engagement and motivation.

By the end of this development stage, the students should have a solid understanding of the concepts of congruence and similarity, and they should be able to apply these concepts in a practical, real-world context. The hands-on, collaborative nature of the activities will have helped to engage the students and deepen their understanding in a fun and interactive way.

# Feedback (7 - 10 minutes)
