Subtracting Integers
Students will subtract integers using the concept of adding the opposite.
Key Questions
- Explain why subtracting a negative number is equivalent to adding a positive number.
- Analyze how the distance between two integers on a number line relates to their difference.
- Construct a real-world problem that requires subtracting negative integers.
Common Core State Standards
About This Topic
The European Union: A Bold Experiment introduces students to the concept of supranationalism, where nations give up some sovereignty to achieve common goals. Students examine the EU's origins as a way to prevent war through economic interdependence and its evolution into a single market with a shared currency, the Euro. The unit also covers the challenges of this integration, including the tension between national identity and European unity.
This topic is crucial for understanding modern geopolitics and the global economy. It aligns with standards regarding the functions of international organizations and the impact of open borders. Students grasp this concept faster through structured discussion and peer explanation as they debate the trade-offs of membership for different types of nations.
Active Learning Ideas
Simulation Game: The EU Council Meeting
Assign students to represent different EU member states (e.g., wealthy Germany, struggling Greece, or neutral Sweden). They must negotiate a new policy on environmental standards or border control that satisfies everyone.
Think-Pair-Share: The Pros and Cons of the Euro
Students consider the benefits (easy travel, stable prices) and drawbacks (loss of control over interest rates) of a shared currency. They share their thoughts with a partner and decide if they would want their country to join.
Gallery Walk: Brexit Perspectives
Display various viewpoints on the UK's decision to leave the EU, including economic, cultural, and political arguments. Students rotate to summarize the different motivations behind 'Leave' and 'Remain.'
Watch Out for These Misconceptions
Common MisconceptionThe European Union is a country like the United States.
What to Teach Instead
The EU is a unique partnership of 27 independent countries. Using a 'Simulation' helps students see that member states still have their own governments and often disagree on major issues.
Common MisconceptionAll European countries are in the EU and use the Euro.
What to Teach Instead
Many countries (like Switzerland or Norway) are not in the EU, and some EU members (like Sweden or Poland) do not use the Euro. Mapping these different 'levels' of integration helps clarify the complexity.

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.
