2. ❓ How do you think inequalities can be applied in your daily life?

3. ❓ Can you think back to a time you (unknowingly) used an inequality to make a decision?

4. ❓ What are the main differences between an equation and an inequality?

5. ❓ What symbols represent inequalities and what does each mean?

Development

Duration: 60 - 70 minutes

This stage is all about giving students the chance to apply and deepen their understanding of inequalities in a practical context. These activities promote collaboration, creativity, and the use of digital tech, making learning dynamic and relevant to their realities.

Feedback

Duration: 20 - 25 minutes

📖 Purpose: This stage promotes reflection and sharing of knowledge, offering a space for constructive feedback among students. It helps consolidate learning, enables recognition of strengths and improvement areas, and fosters communication and collaboration skills.

Group Discussion

📬 Group Discussion: Kick off by having each group share their major discoveries and experiences from the activities. Guide the conversation using the following outline:

1. Introduction: 'Let's start by sharing what we learned today. Each group has a few minutes to present their key takeaways.'
2. Sharing: A representative from each group shares their conclusions.
3. General Discussion: 'As you listened to the presentations, what commonalities or differences stood out in the applications of inequalities?'
4. Conclusion: 'How can we use what we learned today in our studies or daily life?'

Reflections

1. ❓ How did today’s activities enhance your understanding of inequalities? 2. ❓ What was the biggest challenge your group faced, and how did you overcome it? 3. ❓ How did using technology and social media shape your learning about inequalities?

Feedback 360º

🔄 360° Feedback: Instruct students to have a 360° feedback session where every student gives and receives feedback from their peers. Encourage a focus on constructive and respectful feedback using these guidelines:
