Drag the tick on a double number line until the time reads 1 hour and dial what ½ mile stretched into — unit rates from ratios of fractions.
A double number line holds a ratio of fractions such as ½ mile in ¼ hour. The player drags the tick along the time line until it reads exactly 1 hour, both bands stretch by the same factor, and the player dials the stretched distance as a fraction — the unit rate. Flip mode stretches the distance line to 1 instead (hours per mile), and reach mode stretches to 2 or 1½ hours. It targets the misconception that a unit rate is found by subtracting or by guessing; the same ×k on both lines makes the reciprocal visible. Best for Grade 7.
