Graphing Rational Functions: Vertical Asymptotes
Students will identify and graph vertical asymptotes of rational functions based on their denominators.
Key Questions
- Explain what causes a vertical asymptote in a rational function.
- Predict the behavior of a rational function as it approaches a vertical asymptote.
- Compare the graphical representation of a vertical asymptote to a hole in the graph.

About This Topic
Environmental stewardship examines how different cultures approach the protection of the planet and the management of natural resources. For 11th graders, this topic bridges the gap between science and social studies, focusing on the human element of climate change. Students analyze how language shapes our perception of nature and how cultural priorities influence environmental policy. This topic aligns with ACTFL standards by connecting language learning to global issues and community responsibility.
Environmental issues are inherently collaborative and global. Teaching this through active learning allows students to simulate the real-world negotiations that take place between nations and organizations. When students take on the roles of different stakeholders, they begin to understand the complex trade-offs between economic growth and ecological health. This hands-on approach makes the scale of global environmental challenges feel more manageable and highlights the importance of individual and collective action.
Active Learning Ideas
Simulation Game: Global Climate Summit
Students represent different countries at a mock climate summit. They must negotiate a treaty to reduce carbon emissions while considering their country's specific economic needs and cultural values.
Inquiry Circle: Local vs. Global Solutions
Small groups research a specific environmental problem (e.g., plastic waste) and compare how it is addressed in a target language country versus their own community. They create a digital presentation of their findings.
Think-Pair-Share: The Language of Nature
Pairs look at idioms or proverbs related to nature in the target language. They discuss what these phrases reveal about that culture's historical relationship with the environment.
Watch Out for These Misconceptions
Common MisconceptionStudents often think that environmentalism is a modern, Western concept.
What to Teach Instead
Teachers can introduce indigenous practices and historical conservation efforts from various cultures. Using a gallery walk of ancient agricultural techniques helps students see the long history of stewardship.
Common MisconceptionThere is a belief that individual actions don't matter in the face of large-scale pollution.
What to Teach Instead
By calculating the collective impact of small changes within the classroom, students can visualize how individual choices scale up. Active problem-solving tasks help them identify actionable steps they can take.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
