Feedback

Duration: 15 - 20 minutes

This phase of the lesson plan consolidates learning through reflection and shared experiences. The group discussion offers students a chance to revisit concepts, highlight areas for growth, and value teamwork. The 360° feedback fosters an atmosphere of respect and collaboration, encouraging self-evaluation and ongoing improvement.

Group Discussion

Guide a group discussion where students share their experiences from the activities and the conclusions they drew. You might introduce the conversation with: 'Having completed our interactive activities on triangles and their classifications, let’s exchange our thoughts. Each group should briefly present their main learnings, any challenges they faced, and how they tackled those issues. After each presentation, we'll open the floor for questions and comments.'

Reflections

1. What were the biggest challenges you encountered during the activities, and what strategies did you use to overcome them? 2. How did using digital tools enhance or complicate your learning about triangles and their classifications? 3. How might the knowledge about triangles apply in other subjects or in everyday situations?

Feedback 360º

Instruct the students to engage in a 360° feedback session, where each member receives input from their group mates. Stress the importance of providing constructive and respectful feedback. Each student should comment on: (1) What their peer did well; (2) Areas for improvement; (3) A suggestion for future projects.

Summary

🎉 Exciting Summary of Triangles 🎉 To wrap up our lesson, let's do a quick overview with a Top 5 Facts about triangles! 🏆

1. Equilateral Triangle: All sides and angles are equal! It’s the favourite for symmetry lovers. 🎨
2. Isosceles Triangle: Features two equal sides and one different side, along with two equal angles. It’s the triangle of pairs. 👯
3. Scalene Triangle: All sides and angles differ; it’s the 'every triangle for itself' type. 🔀
4. Angles: These can be acute (less than 90°), right (equal to 90°), or obtuse (greater than 90°). 🎯
5. Architectural Use: Triangles are crucial in architecture due to their stability and how they distribute force. 🏛️
