**Angles, probablity, measurement and I fit in ratios as well.**This project has been borrowed by quite a few people and adapted in many different ways. The idea is that the student are pirates and need to bury their treasure. The must make a treasure map and give directions on where the treasure is buried. There are many things you can do with it. Here is my original criteria sheet that I handed out to students. The possibilites of what can be done here are endless.

## Treasure Island

**You are going to be creating a Treasure Map for a special treasure that you have buried on the Isle of Pi. You want to leave a map for your great great grandchildren and you want to make the directions extremely clear.**

**Math**

§

**You must transfer the Isle of Pi onto the large paper at a 2:1 ratio by using the grid technique**
§

**You must have directions that include 2 acute angles, 2 obtuse angles and two reflex angles. The path the treasure hunter would take must be drawn on the good copy of your map.**
§

**You must create two games or puzzles of chance that would have to be completed so that the treasure hunter could continue along your directions.**
o

**One game must be at least a 1 in 6 chance.**
o

**One game must be at least a 1 in 36 chance.**
§

**You must give written directions that include the games of chance and the angles at which a treasure hunter would turn.**
§

**The places where your games take place must be some sort of natural geometric shape that you name.**

**Design and Creativity**

§

**Your island must have natural geographical obstacles that have creative names. (eg. Mount Isosceles).**
§

**All drawings must be neat and colourful.**
§

**Think of any extras that will make the design of your map stand out.**

**I originally gave the students a map of an island and all students worked with it but here are some adaptations that could be made:**

- Students make there own island and design it with different elements of an island
- Take an overhead view of your school or a park and have the students actually plant a treasure there. Have the students make the directions and puzzles for the school site and then challenge others to find it.
- Use non-standard units of measurement for the students by writing the directions like twelve paces or give something with the directions to use as a measuring tool. A trundle wheel could also be used if you want standard measures.

The originality of the designs students come up with is amazing and they had a lot of fun with this project. I did this one about 5 or 6 years ago and enjoyed it but kind of forgot about it until another teacher in my school told me he was doing it. I had a student teacher at the time so I went up to his room to see how the students were doing with it and was amazed at what was produced. In me current job I am going to try (probably next year) having the students create this on school site so that we could have a day or two of treasure hunting.
