Adding and Subtracting Mixed Numbers
Students will add and subtract mixed numbers with unlike denominators, converting between mixed numbers and improper fractions as needed.
Key Questions
- Compare different strategies for adding mixed numbers, such as converting to improper fractions versus adding whole numbers and fractions separately.
- Explain how to regroup when subtracting mixed numbers with unlike denominators.
- Construct a real-world problem that requires adding or subtracting mixed numbers.

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.
