Having an understanding of numbers and how they can be represented is fundamental to mathematical development. As a set, these five beautiful wooden trays show clearly how numbers increase in size. Use them with counters to explore what number bonds can be created on a single tray. Combine trays to explore how numbers relate to each other and can be presented as arrays. Largest tray size: 380 x 80 x 20mm. Smallest tray size: 75 x 80 x 20mm. Made from responsibly-sourced FSC approved beech wood. Age 18mths+. Two-Tone Counting Stones available separately.
