Clear crossings
Lines cross at a clear angle and never touch, so at every crossing it is obvious which way to go on.
Tangled paths: find the way to the goal
Densely tangled paths run from letters at the top to pictures at the bottom. Only one reaches the goal; the rest end at a cross or another picture. Children trace the way by eye or with a pencil through dozens of crossings, a real workout for focus and visual tracking.
Three levels
From a dozen crossings for younger children to over a hundred for patient trackers.
Class sets
Every child gets a different tangle; the key shows the right path in red.
