I wanted a quick to prepare activity to keep Arthur amused whilst I packed the change bag and got us ready to go out. So I poured some salt and glitter into the lid of a biscuit tin and gave Arthur a small make up brush to make some marks, and practice his shapes etc.
He really enjoyed it and didn't make a huge amount of mess, however the mini hoover was on hand ready for the clean up. He really seemed to like effectively rubbing out his marks and starting again, as well as trying to scoop up the salt with the brush. It's a great activity for working his mark making skill in practice for writing, as well as his imagination, as he kept trying to build a snowman!
