Months battleships

Choose five of the things in the list that your teacher gives you and write each one in (exactly) three consecutive months on the top, blank calendar, so that each month has zero, one, two or three activities, and there are fifteen activities on the calendar in total. Each activity must be in three months in a row, e.g. June, July and August (not June, August and October). Any activity can go in any months, so silly combinations like blossom in December are fine. See below for an example.

Take turns asking each other “Do you … in …?” questions about things in the list to find out what is on your partner’s calendar and write the activities in the blank calendar at the bottom of the page if they say “Yes, I do”. Remember that they only have five different things on their timetable and each is in exactly three months in a row, so you don’t need to ask about every activity in every month because:

  • If they have said “Yes” about five different activities, then the other things on the list must not be on their calendar
  • If they say “No, I don’t” about something enough times, that must not be on the calendar at all
  • If three months have an activity, the other nine months must not have that activity
  • If they say “Yes, I do” about something and you later find the nine months that they don’t do that thing, then you can write that activity in all the other months (because only three months will have the activities that they chose)

Whenever you think that you can guess all 15 things on your partner’s calendar, you can show the calendar to them to check if you have written the things that your partner chose in the right months. If you are right, you win the game. However, if you are wrong, then you lose the game.
