Calculations with Rational Numbers and Order of Operations
Students will perform multi-step calculations involving all four operations with rational numbers, applying the order of operations.
Key Questions
- Explain how the order of operations ensures consistent results in complex calculations.
- Analyze common errors made when performing operations with rational numbers and how to avoid them.
- Construct a multi-step problem involving fractions, decimals, and integers that requires careful application of BODMAS/PEMDAS.

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.
