Here's a lovely big beach ball colouring page, perfect for younger children. It also makes an interesting template for a fun craft activity with scrunched up tissue paper.
Beach Ball Colouring Page
Colour in these wiggly surfboards - perhaps in wavy colours like the sea - and then cut them out to mark your position in your reading books...
This pretty colouring page has five intricate illustrations of shells to colour in. A lovely, relaxing colouring activity!
