2. What is the difference between an equation and an inequality?

3. How can first-degree inequalities be applied in real-life situations?

4. What are the main steps to solve a first-degree inequality?

5. Have you ever faced a situation where you needed to solve an inequality in real life? How did you solve it?

Development

Duration: 70 - 80 minutes

This stage aims to stimulate active and participatory learning among students, using digital technologies to make the educational process more engaging and contextualized with their reality. By solving practical problems and creating digital content, students develop a deeper understanding of first-degree inequalities and their application in daily life.

Activity Suggestions

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

Activity 1 - 📱 Mathematical Influencer!

> Duration: 60 - 70 minutes

- Objective: Develop communication skills and use digital technologies to explain mathematical concepts clearly and creatively.

- Description: In this activity, students take on the role of digital influencers and create a video for Instagram or TikTok explaining the concept of first-degree inequalities and solving a practical problem.

- Instructions:

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

• Each group should choose a daily situation that can be solved with a first-degree inequality (for example, budgeting, scheduling, etc.).

• Students must create a script for a video of up to 2 minutes explaining the concept of first-degree inequalities and demonstrating the solution to the chosen problem.

• Use phones to record and edit the video, using apps like Instagram, TikTok, or other available video editing applications.

• Encourage creativity: students can use scenarios, animations, graphics, and any available digital resource to make the video more interesting and educational.

• In the end, the videos will be shared with the class, and the best examples will be highlighted.

Activity 2 - 🕹️ Gamification: Inequality Challenge

> Duration: 60 - 70 minutes

- Objective: Encourage problem solving and logical reasoning through a playful and competitive activity, using digital tools for engagement.

- Description: Students will participate in a gamified competition where they will solve a series of challenges involving first-degree inequalities. Each group will face increasing levels of difficulty to reach the top of the ranking.

- Instructions:

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

• Use a gamification platform (like Kahoot! or Quizizz) to create a series of questions and challenges about first-degree inequalities.

• The challenges will include solving inequalities and applying those inequalities to everyday problems.

• Each group should access the platform via phones or computers and participate in the challenge in real-time.

• The competition is divided into increasing levels of difficulty, with points accumulated for each correct answer.

• At the end, the three groups with the highest scores will receive symbolic prizes or certificates of recognition.

Activity 3 - 📝 Mathematical Storytelling

> Duration: 60 - 70 minutes

- Objective: Foster students' creativity and their ability to apply mathematical concepts in narrative contexts, using digital tools for creating interactive content.

- Description: In this activity, students will create an interactive digital story that involves solving first-degree inequalities. The story should include a practical problem that the characters need to solve.

- Instructions:

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

• Each group should create a story that includes characters, a plot, and a problem that can be solved using first-degree inequalities.

• Students can use digital platforms like Google Slides, Canva or Microsoft PowerPoint to create an interactive presentation or a digital book.

• The story must contain at least three moments where the characters face challenges that require solving first-degree inequalities.

• Each group must present their interactive story to the class, explaining the solutions found for the inequalities within the plot.

• Encourage students to include visual elements, graphics, and interactivity to make the story more engaging.

Feedback

Duration: 20 - 25 minutes

🎯 Purpose: This stage aims to promote reflection, consolidate learning, and strengthen communication and teamwork skills. By sharing experiences and receiving feedback, students gain a broader perspective on their own skills and areas for improvement, as well as enriching their understanding through the contributions of their peers.

Group Discussion

💬 Group Discussion: Promote a group discussion where students share what they learned by completing the activities and their conclusions. Use the following script to introduce the discussion:

Introduction: 'Let's share our experiences about the activities we did today. Each group will have 3-4 minutes to present what they learned, the challenges they faced, and the solutions they found.' Sharing: 'Group 1, please start sharing your work and conclusions.' Questions: 'Does anyone want to ask or comment on Group 1's presentation?' (Repeat for other groups) Closing: 'It was very interesting to hear the different approaches and solutions from each group. Let's reflect on what we've learned and how we can apply this in our daily lives.'

Reflections
