A dotted trail snakes down the page in a serpentine pattern, about three problems per tier across seven tiers, changing direction at each turn. Twenty facts are numbered 1 to 20 along it, with products from 4 to 35. A rocket marks START at the top left, a larger smiling ringed planet flies the END flag at the bottom right, and smiling planets, cratered moons and stars serve as waypoints in between.
There are no branches or choices to make, so this is a themed route to follow rather than a puzzle to solve: the numbering already fixes the order. What it gives a child is a visible sense of progress, since finishing a problem means moving along the trail toward the end planet. Print it when a plain column of facts feels like one page too many.
