**TITLE:** Who’s Who?

**SUBJECT:** This bulletin board can be used in 10th, 11th, or 12th grade average or advanced math course.

**TOPIC:** The topic of this bulletin board is to cover famous mathmaticians, their major contributions to math, and give the students a sense of the history of math.

**INTERACTIVITY:** See Teacher Instructions

**DIRECTIONS FOR USE:** See Teacher Instructions

**TIME:** There are 18 flaps, so it will take approximately 6 weeks to complete, if done every Monday, Wednesday, and Friday.

**SPECIAL CONSTRUCTION:** The flaps are stapled to the bulletin board and held closed with a circular piece of velcros. The strings are thumbtacked, with a flat thumbtack, behind the flaps, and then attached to the country of origin with a round topped straight pin. The inside of the flaps looks as follows:

**CREDIT:** See worksheet and Teacher Instructions(below).

**OTHER COMMENTS:** The mathematicians chosen for the inside of the flaps include: Euclid, Fermat, Newton, Abel, Erotosthenes, Gauss, Galois, Pascal, Euler, etc.

**TEACHER’S INSTRUCTIONS:**

- Every Monday , Wednesday, and Friday have a student pick one of the closed flaps.
- The students will be given two days to submit a contribution.
- The contributions must be submitted with student name, mathematician’s name, contribution, and source. (The sources may consist of another teacher, the Internet, and/or a book.)
- The teacher will check the contributions for correctness.
- On the next day to pick a flap the student chosen to pick a new flap will also record the contributions of the previous mathematician.
- For any student that submits at least 15 correct contributions they will receive a free homework pass.
