Our 'waddle' of penguins will delight children and inspire the use of directional and positional language, problem solving, pattern making, and logical thinking. Specifically designed to embed pre-coding skills through an appealing, tactile resource, these penguins are robust enough to be used in ice, sand and throughout the outdoors. The set contains 18 penguins: four of each directional arrow and two without arrows. Safe for age 2 years and up. Each penguin stone measures 2" .
