Lesson Plan | Technical Methodology | Size Comparison by Terms

Objectives

Duration: 10 to 15 minutes

The purpose of this stage of the lesson plan is to introduce students to the concept of size comparison of objects, fundamental for the development of practical skills. By learning to compare objects, students develop critical analysis and observation abilities, essential skills for everyday activities and for the job market. In addition, the practice of comparing weights and measures prepares students to understand more complex concepts in mathematics and sciences.

Main Objectives

1. Teach students to compare the size of distinct objects, identifying which is the largest, smallest, longest, narrowest, heaviest, and lightest.

2. Develop students' observation and analysis skills through practical and interactive activities.

Side Objectives

1. Encourage teamwork and communication among students.

Introduction

Duration: 10 to 15 minutes

The purpose of this stage of the lesson plan is to introduce students to the concept of size comparison of objects, fundamental for the development of practical skills. By learning to compare objects, students develop critical analysis and observation abilities, essential skills for everyday activities and for the job market. In addition, the practice of comparing weights and measures prepares students to understand more complex concepts in mathematics and sciences.

Contextualization

Comparing sizes is something we do daily, often without realizing it. From choosing the largest apple in the fruit bowl to deciding which backpack to take to school, these decisions are based on comparing sizes, weights, and lengths. Understanding how to compare objects is essential for both everyday life and various professions, such as engineering and design, where measuring and comparing are fundamental skills.

Curiosities and Market Connection

Did you know that civil engineers use size comparison concepts to design bridges and buildings? They need to ensure that the parts of constructions are proportional and safe. In the fashion world, designers constantly compare sizes of fabrics and accessories to create clothes that fit people perfectly. These skills are essential in many careers, showing the importance of learning to compare sizes from an early age.

Initial Activity

Start the lesson with a provoking question: 'Who here has helped set the table for dinner? How did you decide where to place each plate and cutlery?' After a few minutes of discussion, show a short video that illustrates the importance of comparing sizes in real life, such as in construction or creating a work of art.

Development

Duration: 40 to 45 minutes

The purpose of this stage of the lesson plan is to deepen students' understanding of size, weight, and measure comparisons through practical and collaborative activities. These exercises and challenges allow students to apply the concepts learned in a concrete and visual way, reinforcing learning in a significant and fun manner.

Covered Topics

1. Compare the sizes of objects (larger, smaller)
2. Identify longer and shorter objects
3. Distinguish narrower and wider objects
4. Compare the weights of objects (heavier, lighter)

Reflections on the Theme

Guide students to reflect on how size comparison is a skill they use daily, even without realizing it. Ask them to think about situations where they had to choose between objects of different sizes, such as selecting the largest toy or the lightest one to carry in their backpack. This reflection helps to contextualize the importance of the theme and connect it with their personal experiences.

Mini Challenge

Object Challenge

Students will be divided into groups and receive a box with different objects (pencils, erasers, rulers, balls, etc.). They will need to compare the objects and classify them according to size, length, width, and weight criteria.

Instructions

1. Divide the students into groups of 4 to 5 members.
2. Distribute a box with a variety of objects to each group.
3. Ask the groups to discuss and compare the objects, classifying them into categories: largest, smallest, longest, shortest, narrowest, widest, heaviest, and lightest.
4. Each group must create a table or poster to present their conclusions.
5. Facilitate the presentation of each group's results to the class, promoting discussion and collective correction.

Objective: Develop the ability to compare sizes and weights of objects in a practical and collaborative manner, encouraging teamwork and communication.

Duration: 30 to 35 minutes

Evaluation Exercises

1. Provide a sheet with images of different objects. Ask students to circle the largest object in each group of images.
2. Ask students to draw two objects and write next to them which is the lightest and which is the heaviest.
3. Propose an exercise where students must connect similar-sized objects with lines.
4. Create a game where students must sort a series of drawn objects from shortest to longest and from widest to narrowest.

Conclusion

Duration: 10 to 15 minutes

The purpose of this stage of the lesson plan is to consolidate students' learning, ensuring they understand the relevance and practical application of the concepts discussed. Through guided reflection and a recap of the main points, students have the opportunity to internalize the knowledge significantly, connecting it with their daily experiences and future academic and professional needs.

Discussion

 Discussion: Guide students to reflect on the lesson, discussing how each activity helped them better understand the comparison of sizes, weights, and measures. Ask how the experience of working in a group was and how they applied the concepts learned. Encourage them to share examples of everyday situations where they use these skills, such as choosing a fruit at the market, organizing a backpack, or selecting toys to play with.

Summary

 Summary: Review the main points covered in the lesson: the importance of comparing sizes, weights, and measures, and how this applies in various situations in daily life and different professions. Reinforce the concepts of larger, smaller, longer, shorter, narrower, wider, heavier, and lighter.

Closing

 Closing: Explain how the lesson integrated theory and practice through interactive activities, promoting the application of acquired knowledge in a concrete manner. Emphasize the importance of continuing to practice these skills at home and at school, highlighting how they are fundamental for everyday life and for developing future academic and professional skills.
