Activity Suggestions

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

Activity 1 - 🕵️ Mathematical Mission: Equality Detectives 🕵️

> Duration: 60 - 70 minutes

- Objective: Encourage creativity and critical thinking through the creation of stories that involve solving problems with mathematical equalities.

- Description: In this activity, students will turn into mathematical detectives to solve a mystery. Using a storytelling app, such as 'Storyboard That', students will create a story where each clue is associated with an addition or subtraction that needs to be equalized to find the final solution.

- Instructions:

• Divide the students into groups of no more than 5 people.

• Each group will use the 'Storyboard That' app to create a story involving a mystery where the clues are combinations of equal additions and subtractions.

• The stories must include at least 5 different situations with mathematical sentences, such as 3+5=4+4, that need to be solved to continue the narrative.

• Students must insert images and texts to illustrate each situation and clue discovered by the detectives.

• At the end, each group will present their story to the rest of the class, explaining how they reached the mathematical equalities.

Activity 2 - 🎮 Game On: Equality Challenge in Minecraft 🎮

> Duration: 60 - 70 minutes

- Objective: Incorporate gamification into the learning of mathematical equalities, promoting collaboration and logical reasoning.

- Description: In this activity, students will use Minecraft Education Edition to create challenges where different combinations of blocks must result in the same addition or subtraction. They will create worlds with mathematical puzzles that must be solved by other groups.

- Instructions:

• Divide the students into groups of no more than 5 people.

• Each group will have access to Minecraft Education Edition to create a world with 5 mathematical puzzles.

• For each puzzle, students must build structures where the solution involves the equality of additions or subtractions, such as 3+5=4+4, using different types and amounts of blocks.

• After creating the puzzles, groups will swap the worlds they created and try to solve the challenges proposed by another group.

• Students must document their solutions and justify them mathematically, explaining how they reached the equalities.

Activity 3 - 📱 Equality Influencers 📱

> Duration: 60 - 70 minutes

- Objective: Integrate social media into mathematical learning, promoting engagement and communication through digital platforms.

- Description: In this activity, students will become digital influencers on Instagram, creating educational posts and stories that teach their followers about mathematical equalities in addition and subtraction. They will use their cell phones to create content that can be shared on social media.

- Instructions:

• Divide the students into groups of no more than 5 people.

• Each group must think of a creative way to explain mathematical equalities in addition and subtraction, such as 3+5=4+4.

• Using their cell phones, students will create posts and stories for Instagram using tools like Canva or directly through the Instagram app.

• The content must include simple explanations and visually appealing elements to teach the concept of mathematical equalities.

• After creation, students will share their content with the class, explaining the mathematical logic behind each presented example.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to consolidate learning, allowing students to reflect on their experiences, share knowledge, and receive constructive feedback. This promotes a deeper understanding of the content worked on, develops communication and collaboration skills, and reinforces the importance of feedback in continuous improvement.

Group Discussion

Promote a group discussion where each group shares their experiences and conclusions while carrying out the activities. Use the following script to introduce the discussion:

1. Ask students how their experience of working in groups during the proposed activities was.
2. Ask each group to describe one of the mathematical equalities they created and how they arrived at it.
3. Encourage students to share if they encountered any difficulty and how they overcame it.
4. Ask students about the effectiveness of the technologies used and how they helped in the learning process.

Reflections

1. What were the most effective strategies your group used to find mathematical equalities? 2. How did the use of technology (such as storytelling apps, Minecraft, or social media) influence your understanding of mathematical equalities? 3. What did you learn about collaboration and teamwork while carrying out these activities?

360° Feedback

Instruct students to perform a 360° feedback step, where each group member provides constructive feedback to the others. Guide them to be specific, mentioning positive aspects and areas for improvement. Use the following guide to assist with this activity:

1. Each student should list a positive quality they noticed in another group member during the activities.
2. Each student should suggest an area where the other member can improve, always in a respectful and constructive manner.
3. Ensure that all students have a chance to speak and receive feedback.
