I'm always trying to think up new ways to keep the kiddos interested in writing/ mark making. It's funny though, this was one of those spontaneous things, yet was such a success. I had a baking tray full of ground rice after using it to top homebaked muffins with (amayzing btw, but maybe not worth the effor on a Sunday morning when you are hungover!) and figured I'd let Vinnie chuck it all over his playmat or something. It turned into a sort of meditative zen garden sensory play. I think a deeper tray is in order, and maybe a few drops of food colouring or some ground spices chucked over the top the add an extra dimension nex time?
