Comparing Three-Digit Numbers
Using place value logic to compare the magnitude of three-digit numbers using >, =, and < symbols.
Key Questions
- Justify why we start with the largest place value when comparing two numbers.
- Critique a statement that claims a number with more digits is always larger.
- Construct an argument for why comparing hundreds is more important than comparing ones.

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.
