Stack each day's leaves on a plant and watch the bar tops plot themselves — equal steps line up straight, doubling curves away, and you lock in which growth is linear.
Each plant grows by a rule — Fern adds 3 leaves a day, Moss doubles — and the player raises each next-day stack by hand, so the bar tops become the plotted points: equal steps fall on one straight line while multiplied steps curve away. Later rounds hide the rule (set + or × and the amount so your prediction matches every day) and line up three plants to lock in the linear one by reading its day-to-day steps. It targets the misconception that any growing graph is linear, drilling 8.F.3 and 8.F.5: linear means a constant difference, exponential means a constant factor. Best for Grades 7–8.
