Breaking Numbers Down

Players take turns breaking down a number by multiplication. 

• The first player starts with a whole number. 
• The next player makes a string of two numbers that multiply to give the first. 
• The next player then can break down one of the two numbers, making a three number string. 
• The last player who can break it down is the loser of the game. 
• Numbers chosen must be able to be broken down more than twice. 
• A player may challenge if they disagree with a breakdown, or if they say it's the end but it's not. 
• Players may not reuse starting numbers. 1 may not be used in the breakdown. You can't use a number that's been used this session.
• As you play, what patterns do you notice?
