Addition and Subtraction of Integers
Students perform addition and subtraction of integers, including positive and negative numbers, using number lines and rules.
Key Questions
- How does a number line help visualize the addition and subtraction of negative numbers?
- What are the rules for adding and subtracting integers with different signs?
- How can real-world scenarios like temperature changes or bank balances illustrate integer operations?

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.
