Word Problems: Addition and Subtraction
Students solve 1- and 2-step word problems involving addition and subtraction of numbers within 1000, using bar models to represent the problem structure.
Key Questions
- How does a bar model help us understand the relationship between quantities in a word problem?
- What clue words tell us whether to add or subtract?
- How do we check that our answer makes sense in the context of the problem?

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.
