Four Corners Fractions...actually 5

My students are obsessed with Four Corners...so I thought how about incorporating this game into fractions!!!!  So here is what I came up with:
  1.  At each of the five corners post one of each of these- "0". "1/2"/ "1/3", 1/4", and "1". 
  2. Then pass out a fraction card to each student. 
  3. They look at their card and decide which of the 5 numbers their fraction is closest to. They are required to use manipulatives at their desk showing their answer choice before moving to their corner.
  4.  Then we eliminate and discuss those that got theirs wrong. The game continues until there is a winner.
  5. Each new round...pass out new fraction cards. ( I like to have those at their seat still play, just not get up and move)
