Do you know this game? There was a toy version of it and I am sure there is an on-line version. This version is aimed at learners of English who are starting out.
You give everyone in the class the print. Set them into pairs. Direct them to select 10 randomly placed squres on the big grid. This is their own battle fleet. Without showing the other player their print they take turns to guess the other players ships by saying the coordinates. The small grid is to take a memo of hits and misses.
I would recommend players to use something like a file of text to hide their fleet plan.
This game really helps with pronouncing the letters!
Files:
I rather like this, especially for small special needs classes. Can you possibly upload an editable file? pdf to word isn't available at all schools.
