Enhanced provision - seaside theme - any ideas please?

My topic is going to be The Seaside and I am a bit stuck for ideas to enhance my areas. The construction area is proving to be the hardest. So far I have thought of asking the chn to make a boat, but I can't think of anything else for this area.
I am also a bit stuck on the tuff spot. I am going to start by putting sand and seashells in it, but not sure what else I could put in there?
I'm not sure what to put in the maths area, ICT area or Investigative areas either. It is a Year 1/Year 2 class.
I would be grateful if anybody would be kind enough to suggest anything!

 

There was a post similar to this on primary a few days ago with lots of great ideas.
Here is the link;

When we did sea side we added keys to the sand buttons for tresure an old deck chair large box for the children to turn into an ice cream shop creative outside area we also got a pallet and left that for the children to decide what it was one day it was a pirate ship next day it was a stage all these things are very inexpensive and easy to get hold of. we also put sand on a large tarpoline so children could take off their shoes and sox and make patterns,compare feet size etc hope these simple ideas help and cost effective.
