This is a battleship board where going down are the numbers 1-20 and across are the different forms of tener with the appropriate pronouns. Example: Yo Tengo
The students will be in groups and secretly mark 3 different battleships. (1 that's 2 boxes, 1 that's 3 boxes, and 1 that's 4 boxes long)
Their partner will have to guess where their ship is by saying the age. Ex. Yo tengo 3 años.
The other person will tell them "si" or "no" depending whether or not they have a ship there.
