Gildersby Farms Irrigation: Two Clusters in One Scatter Plot
A grade 8 lesson where students plot a fictional farm's irrigation records, find two soil-type clusters and one outlier, and name the association.
Common Core Math · Grade 8
8.SP.A.1 Construct and interpret scatter plots
Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities, describing clustering, outliers, and positive, negative, linear, or nonlinear association.
Why water teaches this standard well
This is the other flagship grade 8 water-math standard: students scatter-plot years of rainfall against reservoir level and describe whether the association looks positive, negative, or roughly linear. Scatter-plotting real climate and reservoir data is the exact task hydrologists perform when studying drought risk.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
