Constructing Triangles
Students will construct triangles given specific conditions for side lengths and angle measures.
Key Questions
- What conditions are necessary to form a unique triangle?
- Why can some sets of side lengths not form a triangle at all?
- How can we use cross sections to visualize three dimensional objects in two dimensions?

About This Topic
Pastimes and Hobbies allows students to explore their personal interests while discovering how people around the world spend their free time. For 7th graders, this topic is a great way to build presentational speaking skills as they describe their own hobbies and learn about new ones. It aligns with ACTFL standards for presentational communication and making connections. Students learn that hobbies are often influenced by geography, tradition, and social trends.
This unit also emphasizes the social aspect of hobbies. Students discuss how sharing a common interest can help them make friends in a new country and build community. This topic comes alive when students can physically model their hobbies through peer teaching and collaborative investigations into the diverse ways people find joy and relaxation.
Active Learning Ideas
Peer Teaching: Hobby Workshop
Students choose a hobby they are passionate about and teach a small group one basic skill or term related to it in the target language. This could be a drawing technique, a dance move, or a game rule.
Inquiry Circle: Hobby Matchmaker
Groups are given profiles of students from different countries with specific interests. They must research and suggest a new hobby from the target culture that would appeal to each student, explaining why.
Think-Pair-Share: The Impact of Technology on Hobbies
Students think about how their hobbies have changed with technology (e.g., gaming, social media). They pair up to discuss if they think these changes are the same for students in other countries and share with the class.
Watch Out for These Misconceptions
Common MisconceptionEveryone has the same hobbies I do.
What to Teach Instead
While some hobbies are global, many are unique to a specific region or culture. Peer teaching and investigations help students discover a wider range of activities they might never have considered.
Common MisconceptionHobbies are just a waste of time.
What to Teach Instead
Hobbies are essential for mental health, skill-building, and social connection. Discussing the benefits of different pastimes helps students see their value beyond just 'killing time.'
