Students and parents of students should read my introduction to letterboxing before seeking the boxes. 

These clues rely on the use of matrices to encode/decode clues. Go
to this page to learn
how to do this on a free graphics calculator simulator or to do it by hand.
Clues: On 18^{th} Avenue off of Paradise Drive, you will see Westhill Cemetery. Take the east entrance or 18th. Turn left on the first path and park. 1) Solve the following: Walk south down the path. Take the second right and keep right at all times. 2) Once you have passed ( t ) ____ nonevergreen trees (to your immediate right) on the route from your car, stop and decode this secret message by using _{}. _{} _{}
Look around and find the gravestone nearby that depicts your solution. Take a moment to admire the beauty of this unique gravestone. 3) Now look north and walk towards Jesus. Enter the public building between the two murals of our Savior and stop when the hall opens up. Before you can find the gravestone you are looking for, calculate the yvalue of the intersection of the following equations. This will determine the bearing you need to turn and face.
4) Using Pascal's Triangle, find the difference of the 3rd entry of the 13th row and the 11th entry of the 12th row. Divide your answer by 2 to determine the column (from the left) that the gravestone is located in. Column number from left = ____ 5) Evaluate the following equation for b to determine the last two digits of the birth year of one of the graves surrounding you. This year will match the birth year of the veteran whom you are trying to find first.
Year = 19____
Now, using the column number and the year of birth you have just found, and find the gravestone bearing the name of our “beloved” math teacher. The person that this gravestone belongs to fought in the same war as the veteran who's grave you will find in the end. (Teacher's note: I'm not old enough to have fought in this war, although they may think so! ;  ) ) 6) Find: Your answer will tell you how many degrees to turn to the right. Walk to the pole you should see. Take a moment to honor all of the men and women who have fought in wars for our country. Now sit by the flag, and look around at your surroundings. You should find the Lord's Prayer engraved on the middle of three stones. Read the Lord’s Prayer, and count the number of lines in the prayer, not including the title.
7) If y varies directly as the number of lines in the Lord's Prayer and indirectly as r, find the constant of variation (k) if y=40 when r= 2:
Write down your answer for later use. k = ____ 8) When facing the Lord's Prayer, turn around 180 degrees and walk back out the way you came. Then turn left when you get to the first road. Your kvalue is the number of rows of graves on the left you should pass as you walk. At the k^{th} row stop and solve the following for g. There are two solutions. Let g be the solution that is a whole number.
Our Remembered Veteran This veteran was born in 1914 and died at the age of 84. He lived in Milwaukee until he moved to West
Bend with his wife Corda, after his retirement.
He was drafted into the war you found earlier at age 26 after the "day of
infamy". He fought in Germany, and was captured. He was a prisoner of war for three
years. After the war was over he was
released, and was given the purple heart in recognition of his accomplishments. He had two children, Ronald and Linda, and
four grandchildren. Upon his death, he
had lived 62 years in blissful marriage. This letterbox was placed by one
of his grandchildren. Before you set out read the waiver of responsibility and disclaimer.
