Ben's rock collection

Mum sent Ben a couple of display boxes for his growing rock collection, plus she cut up some pieces of paper and added a sharpie pen. Ben knew exactly what the boxes were for when he opened his package. Ben and Andrew spent a couple of hours sorting out rocks on the weekend. I just love the way Ben has classified them for now!! I'm looking forward to seeing how the classification system progresses - from "pink" and "green" to "aragonite" and such...
