1. Enable learners to classify flat shapes based on the number of sides and vertices each has.

2. Enhance the ability to compare flat shapes by identifying their unique characteristics.

Tujuan Tambahan:

1. Encourage learners to actively engage in discussions around practical examples of flat shapes, fostering a collaborative and interactive learning environment.

Pengantar

Durasi: (15 - 20 minutes)

The introduction is geared towards engaging students with content they may have encountered at home. It presents problem situations that challenge their ability to apply theoretical knowledge to practical scenarios. Additionally, contextualizing the topic underlines its relevance in everyday life, boosting interest and the perceived value of learning, encouraging students to view mathematics as something vibrant and relevant to their lives.

Situasi Berbasis Masalah

1. Show students a drawing of a park featuring various geometric structures like slides, swings, and fences. Ask them to identify the flat shapes in this setting and discuss how many sides and vertices each shape possesses.

2. Present a series of cards displaying different flat shapes, such as triangles, squares, and circles, and ask students to sort them according to their number of sides and vertices. This activity can be conducted in small groups to encourage discussion and teamwork.

Kontekstualisasi

Discuss the significance of recognizing and understanding flat shapes in our daily lives, from the architecture of buildings to product designs, and even in games like Tangram, which is a traditional Chinese puzzle made up of seven pieces forming a square and five triangles. Emphasize how understanding flat shapes can aid in solving real-world problems and help appreciate the beauty and logic of geometry in the environment around us.

Pengembangan

Durasi: (65 - 75 minutes)

The development stage is designed for learners to apply the knowledge about flat shapes they've acquired in a hands-on and enjoyable way. Working in teams allows them not only to solidify their understanding of sides and vertices but also to develop skills in collaboration, communication, and problem-solving. Each activity aims to reinforce learning in an engaging and meaningful way, ensuring the concepts are understood through practice and interaction with peers.

Saran Kegiatan

Disarankan hanya satu dari kegiatan yang disarankan yang dilaksanakan

Kegiatan 1 - Shape Builders

> Durasi: (60 - 70 minutes)

- Tujuan: Utilise knowledge about the classification of flat shapes in a fun and collaborative manner, reinforcing the identification of sides and vertices.

- Deskripsi: Students will be grouped into teams of up to 5. Each group will receive large cards featuring various shapes (triangles, squares, rectangles, pentagons, etc.). Their challenge is to build a 'city' on a base of craft paper using the shapes provided. They will need to classify the shapes according to their number of sides and vertices, creating distinct neighbourhoods (for example, a neighbourhood made entirely of triangles).

- Instruksi:

• Split the class into groups of up to 5 pupils.

• Distribute the cards with flat shapes to each group.

• Provide a large piece of craft paper as a foundation for the 'city'.

• Students should classify the shapes based on the number of sides and vertices before building their 'city'.

• Each group presents their 'city' to the class, explaining how they organised and classified the shapes.

Kegiatan 2 - Geometric Detectives

> Durasi: (60 - 70 minutes)

- Tujuan: Enhance observation and classification skills while promoting teamwork and collaboration.

- Deskripsi: In this activity, students will work in groups and receive a kit of cards featuring flat shapes hidden in envelopes. Each group must 'investigate' the cards, uncover the shapes, and classify them based on their sides and vertices, using an 'investigation sheet' to document their findings.

- Instruksi:

• Organise students into teams of up to 5.

• Give each group a kit with the hidden cards.

• Explain that they should use the 'investigation sheet' to note the characteristics of the shapes as they discover them.

• Allow them to explore the cards and classify the shapes.

• Afterward, each group presents their findings and conducts a class discussion to conclude the investigation.

Kegiatan 3 - The Shape Parade

> Durasi: (60 - 70 minutes)

- Tujuan: Encourage creativity and understanding of flat shape characteristics while reinforcing learning through a playful and visual activity.

- Deskripsi: Students will organise a fashion show where the 'models' will be flat shapes. Each group gets coloured cardstock of various colours and sizes representing different shapes. They must create a parade, with each shape walking while the group explains its classification based on sides and vertices.

- Instruksi:

• Divide the class into groups of up to 5 learners.

• Distribute the coloured cardstock in different sizes to each group.

• Clarify that each piece of cardstock represents a flat shape, and they must parade the shapes while classifying them by sides and vertices.

• Each group arranges their parade and presents it to the class, explaining each shape.

• Conclude with a discussion about the classifications made by each group, correcting any misconceptions if necessary.

Umpan Balik

Durasi: (15 - 20 minutes)

This stage enables students to reflect on their learning and articulate their understanding in a group setting. Discussing the activities not only reinforces their learning but also develops their communication and argumentation skills. Furthermore, this phase allows the teacher to evaluate student comprehension and identify any areas that require further attention.

Diskusi Kelompok

To start the group discussion, the teacher can invite each group to share what aspects surprised or challenged them during the activities. Then, students should describe the classification and building processes of the shapes, underscoring which strategies worked best and why. The teacher can facilitate the discussion so that everyone gets a chance to speak and share their classmates' ideas, promoting a collaborative learning atmosphere.

Pertanyaan Kunci

1. What were the main characteristics that helped you classify the flat shapes during the activities?

2. Was there any shape that you found particularly tricky to classify? How did you overcome this challenge?

3. How did working in groups enhance your understanding of the sides and vertices of flat shapes?

Kesimpulan

Durasi: (10 - 15 minutes)

The purpose of the conclusion is to reinforce learning, ensuring that students have a clear understanding of the discussed concepts and their practical applications. By summarising and linking theory to practice, this stage helps students internalise knowledge and appreciate its relevance in the real world, providing a great closing chapter to the lesson.

Ringkasan

In the final segment, the teacher should summarize and reinforce the key concepts concerning flat shapes, focusing on identification and classification based on the number of sides and vertices. It’s vital to revisit the hands-on activities undertaken, highlighting common figures like triangles, squares, and circles and their distinguishing properties.

Koneksi Teori

Today's lesson connected mathematical theory with practical activities through engaging tasks. By constructing a 'city' and taking part in parades and investigations, students were able to apply theoretical concepts to real-life situations, aiding solidification of their learning and fostering the view of mathematics as vibrant and applicable.

Penutupan

Finally, it is crucial to underscore the significance of studying flat shapes, as these concepts are fundamental in not just mathematics but also in a variety of everyday scenarios, such as architecture, design, and even games like Tangram.
