Imagine that you have a 9 by 9 chessboard and an unlimited collection of dominoes. The upper left corner, lower right corner, and the square in the very middle of the chessboard are all cut out with an exacto knife. Is it possible to tile the remaining part of the board with dominos? Remember that each domino must cover exactly two squares of the chessboard either vertically or horizontally.
Think you have the answer? Then send me an email at sbr@wfu.edu.
Good Luck!

Resources
Hello, Everyone. Below are links to presentations my students have made at the North Carolina Council of Teachers of Mathematics conference for the past five years. They include lesson plans and student materials. We are working on something for NCCTM this year, which is October 28-29. We are happy to share and hope you can use some of this.
