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!

There are 15 questions altogether Good Luck!
