Thanks to my wife, the students tried out KenKen. This is a type of
Sudoku that also uses simple math to give the puzzle an extra kick.
Here is a link to a site:

They found them to be quite challenging.
The students also did Tangrams. If you search for tangrams, you will
find a number of good sites.
Finally, thanks to Michael for his presentation on Math in
Architecture. Chris will give the next presentation.
Happy Calculating!
