Residuals and Model Fit
Students compute residuals and create residual plots to assess the appropriateness of a linear model. They analyze the plots to determine if a non-linear model might be more suitable.

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.

Scatter Plots and Correlation
Students construct scatter plots to visualize relationships between two quantitative variables. They calculate and interpret the correlation coefficient to measure the strength and direction of linear associations.

Least-Squares Regression Lines
Students calculate the equation of the least-squares regression line and use it to model linear trends. They interpret the slope and y-intercept in the context of the data.
