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.
Park in the parking lot. Start between the oak tree through the roof and
the door to the north of it. (This Bur Oak is one of the largest in Wisconsin.)
When you get to this point, you should be lined up with a cupola,
flagpole, and a square light post.
Soon, you will end up at an object, (a very round and heavy object)
When you get to
this next point, turn to the west and count the number of blue silos off in the
distance: s = _____ Now solve the following for v:
5. On the next object on the north side is a gold serial number, followed by a black on silver serial number. The last 4 digits are a,b,c,d in the following matrix. Decode the matrix and then, walk to the next point and you should be ready to play ball!
6. Make note of the large 2 digit number below the serial number: j = ____
When you get there (or nearby - parallel the spot if being used), FOIL out the following equation. The constant term in the quadratic expression is the number of
paces to take east.
(x + j)(x + s)
8. When you get to this point, solve the matrix below, using the year on the object in clue 3 of this box as a,b,c,d to decode the message and to find where to go next.
Follow the decoded message to the next object. Just in front of it is a mowed
trail. Solve the following problem for k (the constant of variation):
10. When you get to this point on the trail, find the discriminant of the following equation: y=3x2+7x-10, if the equation has 2 different real roots take the trail to the left, if the equation has 1 double root take the trail back the way you came, if the equation has complex roots turn right.
11. Then, walk 72 paces down
that trail, and STOP!! Solve the following for the k - the constant of variation:
You will then reach an intersection of trails.
Note: the actual trail to stay on will go straight, then meander to the right,
then meander to the left. You will stop at a split in the path.
