Um saco inteiro de pedaços de madeira cortados de árvores reais. As crianças podem observar o interior de uma árvore enquanto os usam para classificar e contar. Aprox. 50 peças. Medem 1–1 ½ pol. de diâmetro.
I was surprised how many different ring patterns we found in just one bag—each slice really does show a unique cross-section. My daughter loves lining them up from smallest to largest, and it’s kept her busy for the whole afternoon.
My kids have spent hours sorting these tree rings by size and counting the rings inside each piece—it's turned into a quiet, focused activity. The variety in diameters keeps them engaged, and each cut feels sturdy and natural.
