Everyone needs a rock. Enjoy endless hours of play in the forest, in your back garden, at park, on the beach. here's some suggestions... Find your Perfect Rock It will be not too big and not too small. It will smell right and feel fine. It may be a life long quest. Pebble Toss Create a hole. Each player needs 5 stones. Take it in turns to toss a pebble into the hole. The person with the most stones in the hole wins. Shades of Grey How many different colours of rock can you find? Build up a rainbow of rocks, sorted according to colour. Is the colour related to size, hardness or any other property of a pebble? Trails Make a trail of stones that lead to something interesting. Put a little treasure or surprise to let others know they’ve found the spot!
