Solving Length Word Problems
Students solve word problems involving addition and subtraction of lengths that are expressed in the same units.
Key Questions
- Explain how to determine whether to add or subtract when solving a length word problem.
- Construct an equation to represent a multi-step length word problem.
- Critique a solution to a length problem, identifying any potential errors.

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.
