Stack signed jumps from 0 and throw the REVERSE switch for a negative multiplier — the pod lands on the product, and two reversals face forward again, so (−)(−) = (+).
Integer multiplication as a run on the number line: a jump card b is taken |a| times from 0, and a negative multiplier throws the station's REVERSE switch, mirroring the whole run across zero — so (−3) × (−4) is visibly two reversals that end on the positive side. Players predict the landing flag for a product, then run division backwards by setting the hop count and switch (P ÷ b) or the jump card (P ÷ a). Targets the 'two negatives stay negative' and 'treat it like addition' misconceptions with a miss that names the next move. Best for Grades 7–8.
