Drag five flags — min, Q1, median, Q3, max — along a number line under a dot plot so the box and whiskers draw themselves, then read IQR and compare two box plots.
Raw data appears as a dot plot over a number line, and the player drags five flags — min, Q1, median, Q3, max — onto the right values while the box and whiskers redraw live between them; the flags cannot cross, so order is built in. Read rounds take a finished plot and ask for a quartile, the range, or the IQR on a stepper, and compare rounds put two box plots on one axis and ask for the median difference (negatives allowed), the IQR difference, or the IQR as a multiple. It targets the misconception that quartiles sit a quarter of the way along the axis rather than a quarter of the way through the ordered data. Best for Grade 7.
