Bothersome Brainteasers


Grade: 9

Language: English and French

Has it been a real long time since you have 'troubled' your brain in finding the right answer to a question? In this talk, you will experience four different brainteasers on shapes and patterns to tease your brain and have a good laugh too!

Outcomes:

  • Hone problem solving skills.
  • Explore Eulerian circuits and their mathematical properties.

Candy Game


Grade: 7-9

Language: English

Four of you received four jars full of candies for being respectful to your teacher and your peers! But you find out that not all jars have the same number of candies, and you want to make sure that everyone in your group has the same number of candies. But there is a twist on how you can move candies around, and it's up to you to be fair to your peers in the most efficient way possible.

Outcomes:

  • Study the mathematics behind the strategies to a game.
  • Find leverages to come up with the most efficient method to solve a mathematical problem.
  • Use logic to explain why you method is the optimal method.

Classical Cryptography


Grade: 7-9

Language: English

Cryptography is the study of protecting, coding, storing and transmitting information and messages so that only those who are intended to may read it. In other words, it is the study of secret messages and codes. Encryption is the conversion of messages to the secret code, called ciphertext. In order to read the information normally, on must decrypt the ciphertext, converting it back into plaintext. In this talk, we will look at some classical types of cryptography that were used in old times.

Outcomes:

  • TBA.

Dots and Boxes


Grade: 7-8

Language: English

Dots and Boxes is a game invented by French mathematician Édouard Lucas, who first published a paper on it in 1895. Lucas called it la pipopipette. It is generally a two-player game, although it can be adapted to three or more players. The game is played on a grid of dots, and the goal is to form the most boxes by filling in edges between the dots. Dots and Boxes is an excellent introduction to games involving strategy. Learning this game can increase your capacity for strategic thinking, but it is also a lot of fun! We will guide you through the simple rules by going through an example, and then let you play and experiment to see what outcomes you can achieve.

Outcomes:

  • Introduction to an important and deep branch of mathematics, namely Game Theory.
  • Introduction to posing problems in the context of a game: i.e.: what happens if we change the rules a little bit?
  • Develop strategic thinking in a fun setting.

Eulerian Circuits

  • Solve problems using graphs.
  • Learn definitions involving graphs.
  • Look into different types of graphs.
  • Try to deduce mathematical theorems.
  • Understand why graph theory is so important in real life.

  • What can happen when you sum numbers with a certain pattern.
  • Look into a spatial math sequence and a special number, that appears in nature a lot and is now used in everyday life.
  • Math and art.
  • Math and music.
  • Count the number of solutions to a problem.

Fractions Fun

Outcomes:

  • Adding fractions with different denominators.
  • Represent a given fraction concretely or pictorially.
  • Using fraction addition, subtraction, multiplication, and division to solve problems.

  • Solve problems using graphs.
  • Look into different types of graphs.
  • Try to deduce mathematical theorems.
  • Understand why graph theory is so important in real life.
  • Look into the known problem of map colouring.
  • Applications to scheduling problems.

Jury Duty


Grade: 7-9

Language: English and French

A crime has been committed! By exploring various areas of mathematics, such as logic, graph theory, geometry and more we will see if we can put the guilty party behind bars!

Outcomes:

  • Use math to solve problems that seem to have unpredictable solutions.
  • Attempt to think outside the box to solve math problems.
  • Determine and explain strategies for solving problems or winning games.
  • Understand that a problem might not have a solution and being capable of explaining why.
  • Apply logic to solve problems.
  • Learn how to eliminate possible solutions to a problem.
  • Introduction the mathematical areas that are currently studied: graph theory, cryptography, logic, geometry, algebra and number theory.

Mathemagic


Grade: 7-9

Language: English and French

Can you always correctly guess someones birthday, magically untie yourself from ropes, or read someones mind? You should be able to! It is not magic, it's math!

Outcomes:

  • Use math to solve problems that seem to have unpredictable solutions.
  • Introduction to binary representation of numbers.
  • Review of mental math skills and applying these to concrete problems.
  • Factorization of large numbers.
  • Use spatial skills to solve problems.

Nasty Number Tricks and Devious Divisibility


Grade: 8-9

Language: English

G.H. Hardy (a famous 20th Century mathematiian) wrote: 'Beauty is the first test: there is no permanent place in the world for ugly mathematics'.

Let us face it-algebra can be hard and there will be point for everyone when they find using algebra is difficult. But, believe it or not, algebra can be really beautiful and is, in fact, a powerful tool! Algebra can give a great sense of achievement every time a problem is solved and can, definitely, provide effective methods to break down and solve problems. In this talk, you will feel such a satisfaction and you will see how algebra allows you to take a situation and make it more general by examining nasty number tricks and devious divisibility.

Outcomes:

  • TBA.

Pascal's triangle is an array of numbers arranged in a triangular shape which, upon closer inspection, contains fascinating patterns. In this presentation we explore what information Pascal's triangle contains and discover that it has connections to combinatorics ("art of counting"), number theory, geometry and even fractals. We will also see an idea that seems true, intuitively, but is surprisingly not yet proven.

Outcomes:
