I have been working with an AST to help improve the learning environment in our reception classrooms and one of their recommendations is to have sand and water trays in the classrooms and a bigger sand area outside. This is great for me as I have had a resounding 'no' from my head since asking for a new sand pit outside - ours rotted and had to be removed in September. I have had a look in various catalogues but am not sure which one to go for. Has anyone bought a sand tray that works well inside? For outside I am thinking about an hexagonal sand pit? Thanks in advance for your suggestions and comments.
