Introduction

Duration: (15 - 20 minutes)

The aim of this stage of the lesson plan is to introduce students to the topic of geometric algorithms in an engaging and relatable manner. By using everyday examples and linking them to the job market, students will see how relevant mathematical concepts are in practical situations. Additionally, this initial activity is geared towards stirring students' interest and curiosity, laying the groundwork for the practical activities that will follow.

Curiosities and Market Connection

 Did You Know: Geometric algorithms are instrumental in creating computer graphics and animations for films? They help position objects and simulate realistic movements.

️ Market Connection: In professions like engineering, architecture, and graphic design, geometric algorithms are used to plan constructions, develop projects, and design products. Grasping these algorithms is important for anyone aiming for a career in these fields.

Contextualization

Geometric algorithms are effective tools we use in our day-to-day lives, often without even knowing it. Whether it’s navigating with a map app or putting together artistic designs, these algorithms help us tackle problems and find effective solutions. Let’s dive into how these mathematical ideas can be useful in practical contexts and why they’re vital across a range of professions in our job market.

Initial Activity

 Initial Activity: Show a short video (3-4 minutes) illustrating the role of geometric algorithms in movie animations or video games. After the video, pose the thought-provoking question: 'How do you think the characters in a game know where to move in a scene?' Encourage learners to share their thoughts.

Development

Duration: 60 - 70 minutes

The purpose of this stage of the lesson plan is to deepen learners' comprehension of geometric algorithms through hands-on and collaborative activities. Constructing paper folds allows for direct application of learned concepts, while the exercises and assessments solidify knowledge and evaluate each student’s understanding.

Topics

1. Basic concepts of geometric algorithms

2. Applying geometric algorithms in paper fold construction

3. Indicating an object's movement on a plane using reference points

Thoughts on the Subject

Guide students to reflect on how geometric algorithms feature in their daily lives. Ask about times they’ve used geometric concepts without even realising it, like folding paper for origami or navigating a map. Encourage them to think about how understanding these concepts can help solve problems more efficiently.

Mini Challenge

Creating Geometric Folds

Students will use geometric algorithms to create a geometric figure through origami techniques. The activity will be done in small groups to encourage collaboration.

1. Split the class into groups of 3 to 4 students.

2. Hand out square sheets of paper to each group.

3. Explain and demonstrate how to fold the paper to create simple shapes, like triangles or squares.

4. Challenge students to follow a step-by-step guide to create a more complex geometric figure, such as a star or a cube.

5. Encourage groups to discuss and support each other in understanding the instructions.

6. After the construction, have each group present their figure and describe which geometric algorithms were applied.

Apply geometric algorithms practically through paper fold construction, enhancing understanding of concepts and encouraging teamwork among learners.

**Duration: 40 - 45 minutes

Evaluation Exercises

1. Draw a triangle and a square on a sheet of paper. Show how you could fold the paper to turn the triangle into a square.

2. Imagine you’re designing a map for a game. Describe how you’d use geometric algorithms to position objects on the map.

3. Solve the following problem: 'You have a square sheet of paper. How many folds are needed to create an equilateral triangle?' Explain your thought process.

Conclusion
