This stage aims to contextualize learning, connecting it to the students' daily lives and making the content more meaningful and applicable.

Warming Up

To start the lesson, briefly explain that today students will work on multiplication and division problems using technology and everyday situations. Next, ask everyone to access their phones and look for an interesting fact about multiplication or division that is relevant to their daily lives. For example, they might search for how division is used in recipes or how multiplication is useful for calculating total points in a game. Give a few minutes for everyone to share their findings with the class.

Initial Reflections

1. How do you see multiplication and division being used in everyday life?

2. What are some examples of situations where we would need to multiply or divide?

3. Why is it important to know when to use multiplication and when to use division?

4. Did anyone find any interesting facts that they would like to share?

Development

Duration: 70 - 80 minutes

The purpose of this stage of the lesson plan is to give students the opportunity to apply their multiplication and division skills in real and meaningful situations. By collaboratively working on practical problems, students can deepen their understanding of mathematical concepts and develop logical reasoning and management skills. This playful and contextualized approach aims to make learning more engaging and relevant to students' daily lives.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Digital Influencers: Planning a Giveaway 🎁📱

> Duration: 60 - 70 minutes

- Objective: Apply multiplication and division operations in planning a giveaway, encouraging an understanding of quantities and proportions in a practical and contextualized manner.

- Description: In this activity, students will put themselves in the role of digital influencers. They will plan a giveaway on Instagram that involves multiplication and division of prizes. Students will have to determine the number of prizes needed for a given number of followers and how to divide these prizes among different winners.

- Instructions:

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

• Each group should choose a theme for the giveaway (for example, books, toys, video games).

• Students should access Instagram and research giveaways conducted by real influencers, noting important details like giveaway rules and the number of prizes distributed.

• Students will create a detailed plan for their giveaway, including the total number of prizes and how many prizes each winning follower will receive.

• Using multiplication and division, students will calculate the total number of prizes needed and how those prizes will be distributed among the winners.

• They should create a fictitious Instagram post using templates available in image editing apps like Canva and share their plan with the class.

• Each group will present their giveaway plan to the class, explaining the calculations made.

Activity 2 - Calculating the Recipe: Digital Chef 👩‍🍳👨‍🍳

> Duration: 60 - 70 minutes

- Objective: Develop practical mathematical skills related to multiplication and division, applying them in a relevant everyday context, such as preparing culinary recipes.

- Description: Students will transform into chefs and will have to recalculate a recipe for different group sizes using multiplication and division. They will use recipe apps or websites to find a recipe and adapt it.

- Instructions:

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

• Each group must choose a recipe using popular cooking apps or websites (like TudoGostoso or CyberCook).

• Students should determine how many servings are needed based on different scenarios (for example, a dinner for 3 people, a birthday party for 20 people).

• Using multiplication and division, students will recalculate the amount of each ingredient needed for the different scenarios.

• They can also use online calculators and unit conversion apps to facilitate the calculations.

• Groups should create a digital presentation (using tools like Google Slides) to show the calculations made and the new quantity of ingredients needed for each scenario.

• Each group will present their recalculated recipe to the class, explaining the mathematical procedures used.

Activity 3 - Virtual Market: Shopping for a Party 🛒🎉

> Duration: 60 - 70 minutes

- Objective: Apply multiplication and division operations in a realistic and practical context, teaching budget and financial management concepts in a playful way.

- Description: In this activity, students will simulate shopping for a party using online shopping sites. They will have a set budget and will need to calculate how many items they can buy using multiplication and division.

- Instructions:

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

• Establish a fictitious budget for each group, for example, R$100.00.

• Students should access online shopping sites (like Americanas or Submarino) and choose the necessary items for the party (for example, balloons, sodas, snacks).

• Using multiplication, students will calculate how many units of each item they can buy within the budget.

• They will also need to use division to calculate the unit price of items sold in packages or bulk.

• Each group will create a digital table (using tools like Google Sheets) showing the chosen items, quantity, and total cost.

• Groups will present their simulated purchases to the class, explaining how they arrived at the calculations and if they managed to stay within the set budget.

Feedback

Duration: 15 - 20 minutes

The purpose of this stage of the lesson plan is to consolidate students' learning through reflection and sharing experiences. By discussing in groups and receiving constructive feedback, students can gain new perspectives on their own skills and identify areas for improvement, as well as reinforce collaboration and communication within the class.

Group Discussion

Promote a group discussion with all students, where groups share what they learned while doing the activities and their conclusions. Suggest the following script to introduce the discussion:

1. Start by asking each group to briefly present the activity they did.
2. Ask what the main challenges were and how they solved them.
3. Have the students reflect on the usefulness of multiplication and division operations in the tasks performed.
4. Encourage students to share how these skills can be applied in other everyday situations.

Reflections

1. What were the main learnings you had while doing the activities? 2. How do you think multiplication and division can be useful in your daily lives outside of school? 3. Was there any surprise or discovery during the activities that you would like to share?

360° Feedback

Conduct a 360° feedback session, where each student must receive feedback from other members of the group they worked with on the activity. Guide students to be constructive and respectful, using phrases that start with 'I liked...', 'I think you could improve on...', and 'One thing that surprised me was...'. Emphasize the importance of focusing on the behavior and skills demonstrated during the activities rather than personal characteristics.

Conclusion
