Een hele zak houtstukjes, gesneden uit echte bomen. Kinderen kunnen de binnenkant van een boom bekijken terwijl ze de stukjes gebruiken om te sorteren en te tellen. Ongeveer 50 stukjes. Afmetingen: 1–1 ½ inch diameter.
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.
