Rational Numbers: Fractions and Decimals
Students will define rational numbers and convert between fractions and terminating or repeating decimals.
Key Questions
- Differentiate between rational and irrational numbers.
- Explain the process for converting a fraction to a decimal and vice versa.
- Predict whether a fraction will result in a terminating or repeating decimal without performing division.
Common Core State Standards
About This Topic
Environmental Policy in Europe highlights the continent's role as a global leader in sustainability and green technology. Students examine how European nations cooperate to solve trans-boundary issues like acid rain and the pollution of the North Sea. The unit also explores the 'Green City' model, looking at how urban areas like Copenhagen and Amsterdam use bike-friendly infrastructure and renewable energy to reduce their carbon footprint.
This topic aligns with standards regarding the impact of human actions on the environment and the role of government policy in resource management. This topic comes alive when students can physically model the patterns of pollution and the effectiveness of different green solutions through collaborative problem-solving.
Active Learning Ideas
Inquiry Circle: Designing a Green City
Groups are given a map of a typical industrial city. They must 'retrofit' it with green technologies (wind turbines, bike lanes, green roofs) while staying within a budget and explaining how each change helps the environment.
Simulation Game: The Acid Rain Effect
Using a map of Europe and 'wind' (represented by fans or arrows), students track how pollution from one country's factories travels across borders to damage forests and lakes in another country.
Think-Pair-Share: Personal vs. Government Action
Students discuss whether it is more effective for individuals to change their habits or for governments to pass laws like the 'European Green Deal.' They share their conclusions with the class.
Watch Out for These Misconceptions
Common MisconceptionEnvironmental problems stay within the country where they start.
What to Teach Instead
Pollution is 'trans-boundary' and moves through air and water. The 'Acid Rain' simulation is a powerful way to show students that geography doesn't care about political borders.
Common MisconceptionGoing 'green' is too expensive for most cities.
What to Teach Instead
While there are upfront costs, green cities often save money in the long run through energy efficiency and better public health. The 'Green City' activity helps students analyze long-term benefits versus short-term costs.

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.
