This game works similarly to the game Headbanz, if you have ever played it. This game needs 2 or more players.
You use cards that have numbers 0-10 on them (a deck of playing cards would work)
You can use a paper headband, or can tape the number cards to your forehead to play the game
Tape a number to one player's forehead without them seeing what it is. They will be asking the questions.
They can ask 'more than' questions or 'less than' questions (ex. Is my number more than 5? Is my number less than 3?)
The other players can only answer 'yes' or 'no'
Write out the numbers in a line on a piece of paper, this helps them remember which numbers are still available.
After they ask each question, have them erase or stroke out each number that it can't be (ex. after they ask "Is my number more than 5?" and the answer was "no", they can erase all the numbers that are more than 5)
Continue until there is only one number left and they can ask, "Is my number _____."
