CSUB Lee Webb Math Field Day




An unlimited number of students from each school may participate in the Individual Medley.  Students will work as individuals.  Separate tests and separate prizes will be given for Junior Varsity (freshman/sophomore) and Varsity (junior/senior) events. 

The contest consists of 25 multiple-choice problems from various areas of mathematics:  The time limit for this event is 50 minutes.  Each contestant's score will be the number correct, minus one-fourth of the number wrong. Consequently random guessing, on average, should result in a score of zero. Answer sheets will be provided.  Students will need to bring No. 2 pencils to mark the answers. 


Each school advisor may pick up to 3 students in each level to comprise a school team that will compete in the Team Medley after the lunch break.  Team members will work together on approximately 10 problems during a 50-minute period.  There will probably be at least 4 teams in a classroom, so the team members will need to confer in a quiet manner.


Chalk Talks should last between five and ten minutes. Since speakers should have practiced with this in mind and since our scheduling depends on this assumption, points will be deducted for deviations.  Speakers will be warned when their time is nearly up and expected to terminate their talks quickly.

In evaluating the CHALK TALKS, the various areas such as appropriateness of topic, clarity of presentation, depth and breadth of understanding, effective use of chalkboard and of time should be weighed as indicated below.  However, the finalists and winners will be determined primarily on the basis of the rankings of the speakers by the judges.  Therefore, after having heard all of the talks each judge will individually rank the speakers.

The appropriateness of the topic and the level at which it is treated will be worth 15%.  The speaker's depth and breadth of the understanding of his/her topic as evidenced in his/her talk will count 35%.  (Judges may ask questions following the talk.)  The clarity of the presentation will be worth 30%.  The talk should be clear enough that any above-average student at the speaker's class level would be able to follow it.  Effective use of the chalkboard (and other aids) will count 10%, and effective use of time and staying within the 10-minute limit will count 10%. 


Please note: 1.) Speakers should refrain from referring to notes during their talks, since to do otherwise indicates a lack of understanding of the topic and detracts from the clarity of the presentation.

                 2.) The talks might be scheduled in a room with a "white board".  If so, white board markers will be provided.

Below is a sample judge’s form.

The Math Bowl will be conducted in two divisions:  Junior Varsity and Varsity.  A Junior Varsity Team will consist of 4 students in grades 10 or lower.  The Varsity Team will consist of 4 students in grades 12 or lower.  In each division, team members are to be ranked by the advisor according to ability: 1, 2, 3, and 4, with "1" being the strongest, "2" being the next strongest, etc.  Each contest will consist of 4 rounds.  The number 4 mathlete of each of the competing schools will compete in Round 1, the number 3 mathlete in Round 2, the Number 2 mathlete in Round 3, and the Number 1 mathlete in the final round.  The difficulty of questions increases after each round.

Prior to the competition, each mathlete will receive from the team advisor (who received them at morning registration) a set of answer sheets and fill in the top of each sheet with his/her name, school, round number and question number.

At the beginning of the competition, the round 1 AND 2 mathletes go on stage, bringing their answer sheets.  The round 1 student takes his/her seat and the round 2 player stands behind the chair and will serve as checker.  When everyone is in position, the answer packets will be passed out to the checkers.  At this time they are not allowed to open the answers.

A question will be shown on the screen.  The seated mathletes will begin to work on the problem.  At the same time, the standing mathletes open the answer to that question.  Each problem solver will write the answer on the answer form in the appropriate place, in dark pencil or black or blue ink, and hand the form to the checker.  The checker of the first correct answer will announce "ONE"; of the second correct answer "TWO"; and the third correct answer - "THREE," etc. After their rank is confirmed by the judge the checker will mark the rank on the answer form, with a provided red pen.  At the end of the allotted time, checkers will hand all correct answer sheets to a contest official who will take them to the scoring table. Incorrect answers should be placed in a pile on the floor under the seat.  Scorekeepers will award 5 points for a first, 3 for a second, 2 for a third, and l for all other correct answers.  The scorekeepers will verify that the answers are correct.  Any answer that is deemed incorrect, will invoke a penalty equal to how many points that team would have gotten if  the answer had been correct (e.g. an incorrect second place answer results in 3 points deducted from the score instead of added).  Also of course, if an answer is incorrect, all lower rankings move up by one (this is why it is important to keep track of who’s answer is fourth, fifth, etc.).

At the end of round 1, the two mathletes from each school switch places to prepare for round 2.  At the end of round 2, both mathletes return to the audience and the other two members of each team take their place on stage for rounds 3 and 4.  Scoring is cumulative, and the winning team is the one that accumulates the most points over the four rounds.

Furthermore, please note:

During competition there is to be no communication of any kind between the checkers and the problem solvers.  Violations will be dealt with at the discretion of the math bowl director. 

Though, 9th and 10th graders are eligible to be on a varsity team, no contestant 

may participate in both the junior varsity and varsity competitions.

A team may compete with fewer than 4 participants. A team with 1, 2, or 3 

members participates in the last 1, 2, or 3 rounds.


USE OF CALCULATORS:  No calculators allowed.


Students who wish to compete in this category can recite a poem, sing a song, or present a skit. Students may compete in groups or individually. The presentation should last 3 to 8 minutes and must include at least 40 mathematical terms or phrases. Participants are required to submit a written transcript of their presentation prior to their presentation with the mathematical terms underlined. Students will be judged on their mathematical wit, humor and careful selection of mathematical vocabulary. Winners may be asked to repeat their performance in front of all the Math Field Day participants at the awards ceremony at the end of the day.
