SortWalkPals
Six toys walk down six chalk lanes. In each chalk box, two toys meet and the smaller steps up. Guess: will they swap? Box by box, they walk out smallest to biggest, every time. Rub out one box and find the mix it can't sort, then chalk it on the pavement and walk it for real. Ages 6–8.

Meet the cast
SortWalkPals's friends play on the pavement. Chalky draws the lanes and boxes, Swapple swaps two toys that are the wrong way round, Lanelle keeps everyone in a lane, and Smallfoot always steps up when meeting someone bigger.
Chalky
(Hero and guide, a goose with chalk) - draws six lanes and twelve boxes that sort any order
Swapple
A rabbit in a chalk box - when two meet the wrong way round, they swap
Lanelle
A duck who keeps to her lane - you only move when a box tells you to
Smallfoot
A mouse who steps up - in a box, the smaller one always goes to the upper lane
