CAMOUFLAGED BOX
 

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

 
This box is the second in a series of letterboxes with mathematical clues.  The boxes are intended for both regular letterboxers and my students.  This box was developed by some of my Honors Advanced Algebra students for an extra credit opportunity and as an example for future boxes to be created by my students.

These clues rely heavily 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:

 

Be sure to read through all the clues before looking for the box so you know what is expected of you.


1) Head north on I-43 and take the northernmost Port Washington exit (by the water tower).
What is the exit number? ____(A)

2) Go to Lion's Park (where the water tower is located).  How many sides does the sandbox have? ____ (B)

3) Calculate A + B4 = ______.  Use this four digit number in the following 2x2 matrix to decode where you are to go next:



Drive to the _____________________ downtown.

4) Walk all the way out to the location.  (Be careful with kids!)  On your way, you'll first be on a metal walkway then on concrete.  After about halfway, you'll encounter "foot-high" yellow pipes.  Count the total number of these pipes: _____ (C)

5) Find a year carved into the base of the place.  What are its last two digits? ______ (D)

6) Find C times D = ______.  Use this four digit number in the following 2x2 matrix to decode where you are to go next:



Walk to ___________________________.  Note: You can see the next location on the way back from this one.

7) Find the number of green light posts: _____ (E)

8) Look at the different memorials and find the post Van Ells-Schanen served in: _____ (F)

9) Find E2 x F: _______. Use this four digit number in the following 2x2 matrix to decode where you are to go next:



Drive to _________________________________ in the middle of downtown.

10)  Find the year it was established in: ______ (G).  Use this four digit number in the following 2x2 matrix to decode where you are to go next:



Drive north to ____________________________.  Park on the side of the road by the sign and the stairs leading up.

11) Walk up all of the stairs - all the way up to its doors.  How many total steps are there? _____ (H)

12) Find H2 = ______.  Use this four digit number in the following 2x2 matrix to decode where you are to go next:



Go to ________________________________________________________________

BEFORE RETRIEVING THE BOX, BE SURE NO ONE IS AROUND TO SEE YOU TAKE THE BOX OUT!  DO NOT BRING ATTENTION TO YOURSELF OR THE HIDING LOCATION OF THE BOX!

13) Find Anna Koppe's tree in the northeast corner.  In a hole in its bottom towards the back you will find the letterbox!

Good luck!
