Problem Solving with Rational Numbers
Students apply addition and subtraction of rational numbers to solve multi-step word problems, including those involving money and measurements.
Key Questions
- How do we determine the appropriate operation(s) when solving word problems involving fractions or decimals?
- What strategies can be used to break down complex word problems into manageable steps?
- How can we check the reasonableness of our answers in real-world contexts?

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.
