here is a thread from this board about this subject - pros/cons

Here are some instructions I found on a google search for someone making a board game - maybe you can piece all of these things together and come up with something.

"Basically, the idea is to create a board game that 2-4 kids could pick out of a box and play (quietly and w/o help from the teacher) if they have free time or finish an assignment early. Everyone in my class will be making one and will also be duplicating the "board" so we can all leave the class w/ a huge box of math games. The "board" is actually a large file folder, and any pieces/dice/etc. must be able to fit in a ziploc bag inside the folder. Make sense???

I can base it on any of these areas:

Algebraic Thinking: Patterns and Functions

Geometry: Congruence and Similarity, Visualization, Symmetry and Transformations, Tessellations, Geometry in 3D

Measurement: Perimeter, Area, Measurement in 3D

Statistics

Probability
