Double Take 
Copy onto cards the equations shown below. Shuffle the cards and place them face down in a pile. Decide which partner will go first.
Equations to put on cards: 

x + 34 = 52 
9 + x = 20 
x  6 = 23 
x + 17 = 51 
x + 4.85 = 9 
x = 4.85 
x = 18 
x + 8.7 = 19.5 

14.15 + x = 19 
x = 14.8 
x = 29 
x  2.3 = 12.5 
x = 4.15 

x = 34 
x = 17 
x = 10.8 
x = 11 
Each partner begins with 50 points. In turn, each partner removes cards from the pile until he or she finds two cards containing equivalent equations. Subtract 1 point for each card taken. Combine and shuffle all the cards. Then repeat the procedure. The winner is the partner with the most points after five rounds.
