3 strikes and
you’re out
This game is called “3 strikes and you’re
out” because each time you make a
mistake you lose a life.
Once you have lost all three of your
lives, you are out (for now).
Some questions are easy and some are
hard. Just give each question your best
guess.
Each question has 2 possible answers: one on
the left and one on the right. You must
choose which you think is correct and stand
on that side of the line. If you are wrong, you
lose a life!
Count the lives you have lost by holding up
fingers in front of you. Hold up one finger for
each life lost.
If the whole class is out, then everyone is
back in again!
