Multiplying and Dividing Decimals by 10, 100, and 1,000
Students will understand the concepts of approximation and error, including absolute and relative error, in practical measurements.
Key Questions
- What happens to the digits of a decimal number when you multiply by 10, 100, or 1,000?
- How do you use place value to divide a decimal by 10 or 100?
- Can you apply multiplication of decimals by powers of 10 to solve a real-world measurement problem?

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.
