• We made a new logic game. In it we drew a graph using circles and lines, and throughout this blog entry when I refer to a graph I’m refering to the type of mathematical graph used in graph theory, representing objects and the links between them, though you don’t need to know anything about graph theory to play the game. These are the rules: You have to put Xs and Os into the circles and the lines told the relationship between two connected circles. If the line has a heart next to it then the connected circles had the same symbol in it. If the line did not have a heart then the symbols were…
