Data Collection and Bias
Students will understand different data collection methods and identify potential sources of bias.
Key Questions
- Analyze in what ways data collection methods can introduce bias into a study.
- Critique different sampling methods for their potential to produce representative data.
- Design a fair and unbiased method for collecting data on a given topic.

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.
