Properties of Triangles
Classifying triangles by sides and angles, and understanding the sum of interior angles.
Key Questions
- Differentiate between various types of triangles based on their side lengths and angle measures.
- Justify why the sum of angles in any triangle is always 180 degrees.
- Design a method to determine if three given side lengths can form a valid triangle.

About This Topic
Volunteerism and Giving Back explores the importance of community service and the values of empathy and compassion. In the S1 curriculum, this topic covers the different ways students can contribute to society, from formal volunteering to simple acts of kindness. They learn the language of service, focusing on how to offer help respectfully and how to describe the impact of their actions.
This unit encourages students to reflect on their own motivations for giving back and the personal growth that comes from helping others. They explore the diverse needs within the Singaporean community and the role of various social service organizations. This topic comes alive when students can engage in real or simulated service experiences, practicing their communication skills in a meaningful and impactful way.
Active Learning Ideas
Simulation Game: The Volunteer Fair
Students role play as representatives of different charities or as potential volunteers. They must discuss the mission of the organization and how volunteers can help, using Mother Tongue.
Role Play: Offering Help with Dignity
Students practice scenarios where they offer help to someone in need (e.g., an elderly person with heavy bags). Focus on using polite and respectful Mother Tongue phrases.
Think-Pair-Share: The Impact of Giving
Students reflect on a time they helped someone or were helped by others. They share the experience and the feelings it evoked with a partner, using descriptive language.
Watch Out for These Misconceptions
Common MisconceptionVolunteering is only for people with a lot of free time or money.
What to Teach Instead
Students often think of service as a grand gesture. Use brainstorming to identify small, everyday ways they can contribute to their community.
Common MisconceptionHelping someone means you are 'superior' to them.
What to Teach Instead
Students may unintentionally adopt a patronizing tone. Role plays help them practice offering help in a way that respects the dignity and autonomy of the other person.
