The Cake Problem

K2B made two cakes. They asked if we can help with the frosting and cutting. We agreed.

The mathematicians thought about the problem. We had 2 cakes. We needed 16 pieces from each cake. The pieces must be the same size. First, we talked about the shape of the cake.

  • Patrick “The cake is a rectangle. Two sides are the same length, two sides shorter and two sides longer.”
  • Eunice “We draw rectangles because we have to think about how to cut it.”

  • Euijin “We draw 16 pieces.”
  • Kenan “We need to draw the 16 people. We have to make two 16’s.
  • Joon “It is 16 pieces.”

  • Patrick “We are erasing and fixing the pieces to make it right. When you don’t get it correct, you need to erase and try again.”
  • Noah “We are sharing our drawings.”

  • Doho “We draw and we show them.”
  • Sean “We can cut the cake 2 ways.”
  • Doho “We cut the cake.”

  • Eunice “We put the cream.”
  • Patrick “The cake looks like pancakes or cheesecake.”
  • Euijin “The cream cheese.”
  • Eunice “It’s almond cream.”
  • Patrick “It is sugar cream.”
  • Allen “I think this cream is white chocolate.”
  • Doho “Very YUM!”
