A paper version of the old boardgame. Using vocabulary!
Each student gets 2 pages, exactly the same. I usually staple them together. The front page will be used to take notes later.
On the second page the students draw 5 ships.
Air Craft Carrier (5 squares)
Battleship (4 squares)
Cruiser (3 squares)
Submarine (2 squares)
Patrol Boat (2 squares)
They can draw them where-ever they like vertically or horizontally. They CANNOT draw them diagonally or overlapping. Remind them to keep it a secret.
Once they finish drawing they should cover their paper.
They will make pairs and play rock-paper-scissors. The loser/winner asks first.
They guess the location of their partner's ship by making a sentence. i.e. what is the weather forecast for tomorrow in Abashiri (or whatever place name you want to use.)
Their partner will check their second page. If there is a ship they say 'hit' and the partner who asked will draw a circle on their memo paper. If there is no ship, they say 'miss' and the person who asked will draw an X on their memo paper.
Once all the squares of a ship are hit the student must say 'sunk'
The goal is to sink all 5 of their partner's ships.
