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.  
Be sure to read through all the clues before looking for the boxes so you know what is expected of you.
Start at Morning Star Lutheran School: N171W20131 Highland Road, Jackson, WI 53037. If you go east from Hwy 45 on Hwy 60 to Jackson Dr., you might spot a pink flamingo near the Post Office! On your way north of Hwy 60 on Jackson Dr., you might also spot a clue on the way to Highland Road......
1. Begin at the flagpole in front of the school Count the number of red stripes on the flag, this number goes into the first blank below. Now count the number of white stripes, and put this number into the second blank below.
(X+ __) (X+ __) = ax^{2} + bx + c
the number of stars on the flag to get your first bearing. _______
2. Count the number of boards that make up one bench by the flagpole, and insert this number into the second blank below. Then walk on the bearing you found above until you meet a large door. Count the number of rows of rectangles on the garage door, insert this number into the first blank.
( X+ __ ) ( X+ __ ) = ax^{2} + bx + c
3. Find the value for each letter and substitute the values for the corresponding letters of the matrix.
Now add these two matrices and find out what letters
correspond with each number in the new matrix ( Space=0, A=1, B=2, C=3, D=4,
etc. ) This will tell you where to go next.
4. Once you reach your destination, start at the large camouflaged machine of war. Stand in front of the rock and look at the water tower. Determine the number of letters in the color of the water tower and insert this number into the space labeled X. To find Y take the number of big wheels on the tank times 97/7.
X Y 384
Determine the common difference between each number. This is your next bearing. Walk in that direction.
5. When you come to the large fence, walk along the fence to the west until the end. Count the number of courts along the way and substitute this value for x in the following direct variation equation:
1104 = kx If k < 180, take 30 paces on a bearing of k. If k > 180, take 60 paces on a bearing of k.
6. Find the value for each letter and substitute the values for the corresponding letters of the matrix
Now add these two matrices and find out what letters correspond with each number in the matrix This will tell you where to go next. (Hint: NW)
7. Find the roots to this quadratic equation.
x^{2} + 5x  14 = 0
Take the positive root and multiply it by the speed limit on the sign nearby. This will give you the number of paces you are to take north from the back right (NW) corner of the fence.
8. But before you go, solve the next clues....
Step 2:
Decode the matrix below to see what you may be missing for Step 2. Find the value for each letter and substitute the values for the corresponding letters of the matrix. (A= 1, B= 2, etc.)
a# of letters on the Jackson water tower b# of license plates you are to have on your car in Wisconsin. c What # mathman letterbox is this d#of people who made this letterbox
Step 3:
Step 4:
__x^{2} +
__x  ___ Step 5:
