Double Bar Graphs: Scale, Structure, and Comparison

Create a 6–8 slide Grade 5 mathematics review deck for a 15-minute teacher-led consolidation. Slides should: (1) define a double bar graph as a comparison of two related data sets across shared categories; (2) label title, horizontal axis, vertical axis, legend, baseline, paired bars, and equal intervals; (3) explain a scale of 5 with a clear visual example; (4) model constructing paired bars from this illustrative data: Bed A Green 20/Blue 15, Bed B 35/25, Bed C 10/20, Bed D 30/40; (5) contrast correct and flawed graphs showing unequal intervals, missing legend, or a nonzero baseline; (6) model put-together, take-apart, and compare reasoning from graph values; (7) model a two-step comparison using two differences; and (8) end with a concise construction-and-reading checklist. Include teacher pause cues and accessible visuals. Do not turn the deck into a quiz.
