MATHEMATICS PAPAHANA
The Mathematics Papahana is an annual contest sponsored by Saint Louis
School.
The contest is open to 7th and 8th graders throughout the state.
Schools may register a team by contacting the school
operator (739-7777, ext. 0) and leaving a message for the Mathematics Department
(739-4877) or math@saintlouishawaii.org.
This year's contest will be on March 18, 2006.
In
addition to the events, students sharpen their understanding of probability in
the casino which is open to all participants throughout the contest. An
auction takes place just before the awards ceremony with teams bidding against
one another for the coveted bounty found in the auctioned boxes.
A 3-D tic-tac-toe gives students the opportunity to
hone their
spatial skills.
CONTEST EVENTS
WIKIWIKI
Approximately fifty (50) multiple-choice problems will
be flashed on a screen in definite time intervals. Every contestant will darken
the space for the appropriate answer onto the SCAN-TRON ANSWER SHEET
which will be made available to them. The contestant will receive five (5)
points for each correct answer and zero (0) point for each incorrect or blank
answer. The time limits for each problem may vary from 5 seconds to 30 seconds
which dictates that the problems are "inspection problems" or problems
having very little calculations in their solutions. Since each problem flashed
on the screen will have a time limit, this event stresses speed and accuracy.
This event is open to two (2) students from each respective school in the 7th
and/or 8th grades.

HO’OKUKU
An event in which the students "compete" in
four track and field events. The first event is the "SHOT PUT" which
is 10 minutes long consisting of the column addition of whole numbers. The
second event is the "HIGH JUMP" which is 10 minutes long consisting of
the multiplication of whole numbers. The third event is the "MILE RUN"
which is 5 minutes long consisting of the multiplication and division of proper
and improper fractions and mixed numbers. The fourth event is the "BROAD
JUMP" which is 5 minutes long consisting of the addition and subtraction of
proper and improper fractions and mixed numbers. The problems in each event are
weighted the same, five (5) points for each correct answer. However, the scoring
in each event will stop for the individual student as soon as an incorrect
answer is made by the student. Therefore, this event is based primarily on speed
in handling the four basic operations with whole numbers, mixed numbers and
fractions. This event is open to two (2) students from each respective school in
the 7th and/or 8th grades.

PAAKIKI
This event consists of forty (40) multiple-choice
problems. The contestants will attempt to solve as many of these problems as
possible in 50 minutes. The contestant will darken the appropriate space onto
the SCAN-TRON ANSWER SHEET. Five (5) points will be awarded for each
correct answer and zero (0) points for each incorrect or blank answer. This
event calls for students that are good at problem solving. This event is open to
two (2) students from each respective school in the 7th and/or 8th
grades.
SAMPLE PROBLEMS:
1.

3-D TIC TAC TOE
While papers are being corrected, those students who
have a name tag may participate in this event. The students will be broken up
into three random groups and the champion will be determined from the winners
from each group. THIS IS NOT PART OF THE
PAPAHANA SCORING EVENTS.
The object of the game is to place four marks (X or O)
in a straight line, horizontally, vertically, or diagonally, all on one level or
one on each of the four levels. The winner is the first contestant who
accomplishes this. The overall winner wins a trophy.
CASINO
The CASINO will be open to those students who have a
name tag. The CASINO gives students a chance to play games and learn a little
bit of probability while waiting for their events. THIS IS NOT PART OF THE
PAPAHANA SCORING EVENTS.
