Overview
Details about the 2018 ISSEA STEM Mathematics events are described below.
Updates and further information will be posted in the Math Forum, and students and teachers are encouraged to use the forum to ask questions and share ideas. If you have questions, contact Rob Maddock, who is organizing the Mathematics aspects of the tournament. Scroll down to the bottom of this page for some helpful resource links. |
Guidelines and Scoring for 2018 ISSEA STEM Mathematics events:
ISSEA STEM participants will be placed into either Division 1 or Division 2 depending on their current grade level.
Scoring for the math component of ISSEA STEM will be based on three equally weighted rounds as follows:
In the unlikely event of a tie, it will be broken by (in order): the total number of correct answers made by the school, OR if still tied, the total number of 8-mark questions correct from the Multiple Choice round, OR if still tied, the total number of 6-mark questions correct from the multiple Choice round, OR if still tied, a tie is declared and both schools receive equal rank. This ranked score determines the school's math component score for overall ISSEA standings with a 1 to 8 ranking.
- Division 1: For students currently in grade 9 and below
- Topics covered may include: ratio & proportion, patterns, logical thinking, basic probability, basic geometry, similarity, linear functions, systems of linear equations in two variables, arithmetic sequences & series, problem solving
- Division 2: For students currently in grade 10 and above
- Topics covered may include: all topics from Division 1, quadratics, sum and product of roots of a quadratic, geometric sequences & series, function notation, transformations, counting techniques (elementary permutations and combinations), elementary trigonometry (including sine and cosine law), circle geometry
Scoring for the math component of ISSEA STEM will be based on three equally weighted rounds as follows:
- Individual Round #1
- Individual Multiple Choice (IMC) round for Division 1 and Division 2
- 25 questions (choices A, B, C, D, E for each question)
- 1 hour
- three levels of increasing difficulty
- Part A 10 questions, 5 marks each
- Part B 10 questions, 6 marks each
- Part C 5 questions, 8 marks each
- Maximum score 150 marks
- no calculators allowed
- no penalty for wrong answers
- Individual Round #2
- Individual Full Answer (IFA) round for Division 1 and Division 2
- all answers are integers
- 15 questions
- 1 hour
- 10 marks for each correct answer
- maximum score 150
- calculator is allowed (no CAS or dynamic geometry systems)
- questions gradually increase in difficulty
- no penalty for wrong answers
- Team Round #1
- Crocodile's Tail Team event for Division 1 and Division 2
- See this video of the Crocodile's Tail competition in action at Hong Kong International School
- See this video of the Crocodile's Tail competition in action at Hong Kong International School
- teams of 3
- 30 questions
- 1 hour
- 5 marks per question
- 150 maximum marks
- no calculators
- two optional bonus questions (longer and more difficult) are given to the teams at the start of the hour -- these can be handed in any time during the hour to receive a bonus 10 points each if correct
- Crocodile's Tail Team event for Division 1 and Division 2
- Team Round #2
- composed of team members from different schools
- active Amazing Race problem solving format
- will not count toward the overall point count for the math component but will engender camaraderie amongst schools and be a fun event
- awards for the highest Team Round #2 scores at the awards ceremony
In the unlikely event of a tie, it will be broken by (in order): the total number of correct answers made by the school, OR if still tied, the total number of 8-mark questions correct from the Multiple Choice round, OR if still tied, the total number of 6-mark questions correct from the multiple Choice round, OR if still tied, a tie is declared and both schools receive equal rank. This ranked score determines the school's math component score for overall ISSEA standings with a 1 to 8 ranking.
Resources
In order to prepare well for the competition, participants are advised to use the following sites to practice different style questions:
- Logic Puzzles - includes sample logic questions and challenges that will be useful for the Math team round/competition
- Other resources for team round: Tangrams, Tangram Channel, Sudoku
- Centre for Education in Math and Computing (University of Waterloo) - repository for questions and solutions used in annual Math contests
- South African Maths Olympiad - official site of the South African Maths Foundation affiliated with the International Mathematical Olympiad
- Math Counts Foundation - has lots of great advice plus a 'Problem of the Week' section with some great practice questions.
- International Math Olympiad - has past Math problems dating back to 1959 - lots for you to download and practice with!
- Joy of Creative Math Problem Solving - has a bunch of links with thousands of Math problems and answers.
