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!”
