Lesson Plan | Active Learning | Basic Addition Facts

Assumptions: This Active Lesson Plan assumes: a 100-minute class, prior student study with both the Book and the start of Project development, and that only one activity (among the three suggested) will be chosen to be conducted during the class, as each activity is designed to take up a significant portion of the available time.

Objectives

Duration: (5 - 10 minutes)

This stage of the lesson plan is crucial for establishing a solid understanding of the fundamentals of addition, essential for the students' mathematical development. By clearly defining the objectives, the teacher aligns learning expectations and prepares the ground for interactive and applied activities, facilitating the transition to in-class practice. This clarity helps students focus on the key aspects of learning addition and effectively apply the knowledge acquired during the lesson.

Main Objectives:

1. Ensure that students understand the basic facts of addition as simple sums that form the foundation for all other addition operations.

2. Develop the ability to perform basic addition operations, such as 2 + 4 = 6, independently and correctly.

Side Objectives:

1. Encourage active participation of students during the discussion of pre-taught concepts at home.
2. Promote students' confidence in their mathematical skills through positive feedback and continuous support.

Introduction

Duration: (20 - 25 minutes)

The introduction of the lesson, through problem situations, aims to engage students in active reflection on their prior knowledge of addition, encouraging them to apply this knowledge in practical scenarios. The contextualization of the theme, with everyday examples, helps reinforce the relevance of learning addition in daily life, facilitating students' understanding and interest in the subject.

Problem-Based Situations

1. Imagine you have 3 apples and your friend gives you 2 more apples. How many apples do you have now? Discuss with your classmates how you arrived at the answer.

2. If at a birthday party there were 4 balloons hanging on the wall and 3 more were added, how many balloons are decorating the wall now? Use drawings to represent the balloons and sum them.

Contextualization

Addition is a fundamental mathematical skill that we use in our daily lives. For example, when we go to the market and buy items, we need to sum the prices to know how much we will pay. Or when we are sharing candies among friends, we need to calculate to ensure everyone receives the same amount. Understanding addition is essential for many everyday activities, making learning this concept very practical and necessary.

Development

Duration: (70 - 75 minutes)

The development stage is designed to allow students to apply the addition concepts they studied at home in an interactive and practical environment. By working in groups, students have the opportunity to discuss strategies, solve problems together, and learn from each other, consolidating their understanding of the basic facts of addition in creative and engaging ways. Each proposed activity here is developed to maximize student participation and apply mathematical knowledge in practical and enjoyable contexts, thus ensuring effective and meaningful learning.

Activity Suggestions

It is recommended to carry out only one of the suggested activities

Activity 1 - Math Mini-Market

> Duration: (60 - 70 minutes)

- Objective: Practice the addition of numbers in a shopping context, developing calculation and estimation skills.

- Description: In this activity, the classroom will be transformed into a small market, where each group of students will receive a basket and the task of 'buying' items labeled with simple prices. Each item will have a tag with a number representing its cost, and students will need to sum the values to determine the total spent.

- Instructions:

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

• Give each group an empty shopping basket.

• Spread labeled items with prices around the classroom.

• Each group must choose items that, when summed, do not exceed a limit set by the teacher.

• Students must calculate the total cost of the chosen items.

• Each group presents their choices and explains how they performed the sums.

Activity 2 - Number Builders

> Duration: (60 - 70 minutes)

- Objective: Develop cooperation and teamwork problem-solving skills by applying addition concepts to achieve a common goal.

- Description: Students will be challenged to build numbers using building blocks, where each block has a number. The goal is to form a structure whose sum of the numbers on the blocks equals a target number given by the teacher.

- Instructions:

• Each group receives a set of numbered blocks.

• The teacher announces a target number.

• Groups must use the blocks to build a structure whose sum of the numbers equals the target number.

• Students should discuss and test various combinations of blocks to reach the target number.

• Present the final structure and explain the addition process used.

Activity 3 - Number Picnic

> Duration: (60 - 70 minutes)

- Objective: Stimulate the practical use of addition in financial planning situations, promoting calculation and decision-making skills.

- Description: Students plan a picnic by choosing items from a menu with prices, where they must calculate the total cost of their picnic without exceeding a defined budget.

- Instructions:

• Organize students into groups of up to 5.

• Distribute a picnic 'menu' with items and prices.

• Set a maximum budget for each group.

• Students select items from the menu that they would like to include in their picnic, summing the prices to ensure they do not exceed the budget.

• Each group presents the result of their planning, explaining the choices and sums made.

Feedback

Duration: (15 - 20 minutes)

This stage of the lesson plan is essential for students to verbalize and reflect on what they have learned, allowing the teacher to assess each student's understanding of the fundamental concepts of addition. The group discussion also strengthens social and communication skills as students share different perspectives and learnings, enriching everyone's educational experience.

Group Discussion

Start the group discussion by asking each group to share their experiences during the activities. Encourage students to explain how they arrived at the solutions to the proposed problems and which strategies were most effective. Reinforce the importance of discussing and reflecting on the methods used, as this helps consolidate learning.

Key Questions

1. What strategies did you use to solve the addition problems during the activities?

2. Was there any moment you found difficult? How did you overcome that challenge?

3. What did you learn about addition that you didn't know before the activities?

Conclusion

Duration: (5 - 10 minutes)

The purpose of this stage is to consolidate students' learning, ensuring that they can connect mathematical concepts with their practical applications. Summarizing the key points helps in retaining knowledge and provides a clear view of how addition is used in daily life. This final reflection is vital for students to realize the relevance of what they learned and how they can apply this knowledge in various situations.

Summary

In this lesson, we explored the fundamentals of addition through practical activities that simulate everyday situations, such as shopping and event planning. Students practiced adding simple numbers, reinforcing the understanding that addition is an essential tool in daily life.

Theory Connection

The flipped classroom methodology allowed students to apply the theory studied at home, using it in practical activities during the lesson. This not only facilitated conceptual understanding but also showed how addition applies in various practical contexts.

Closing

Understanding and applying addition is crucial as it is a fundamental skill in solving everyday problems and in developing logical and mathematical reasoning. By integrating addition into practical activities, students were able to see the real value of this mathematical operation in their lives.
