The 1, 2, 3, 4, 5 - Frame Tray Set from Yellow Door is an engaging resource designed to support early mathematical development. Each of the five beautifully crafted trays demonstrates how numbers increase in size and can be represented in a clear, tactile format. Children can use counters or small objects to explore number bonds within a single tray or combine multiple trays to investigate how numbers relate to one another and can be arranged in arrays. Made from FSC-certified beech wood, the set offers both durability and sustainability. The largest tray measures 380 × 80 × 20 mm, while the smallest is 75 × 80 × 20 mm, making them suitable for little hands to manipulate with ease. Safe for children aged 18 months and older, this versatile set encourages hands-on learning, curiosity, and a deeper understanding of number patterns and relationships.
