Residuals and Model Fit
Students analyze residual plots to evaluate the appropriateness of a linear model. They also interpret the coefficient of determination to understand the proportion of variance explained by the model.
About This 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.

Scatterplots and Correlation
Students create scatterplots to visualize the relationship between two quantitative variables. They assess the direction, form, and strength of the association and calculate the correlation coefficient.

Least-Squares Regression
Students calculate and interpret the least-squares regression line for a set of bivariate data. They use the model to make predictions and interpret the slope and y-intercept in context.
