NS Math Circles is expanding to include Elementary Schools!

The below is a list of presentations appropriate for elementary school classes, in alphabetical order. If you would like us to come and give any of these presentations in your classroom for free, please use the contact form on the School Visits page.

Exploding Buckets

We explore a classic problem of placing numbers into buckets. Be careful though: a bucket will explode if two numbers add to a third number in the same bucket (ex: 1+2 = 3 KABOOM!). How many numbers can you place into two buckets without the buckets exploding? Three buckets?

Outcomes:

• Use mental math to determine a sum to 20.
• Understand the order in which numbers are added does not affect the sum.
• Estimate the sum of two numbers to determine if it is larger than another number.

This presentation can also be done with a grade 1 class as long as your students can add up to 20.

Exploring Mathematics

Explore mathematics with a series of small problems which investigate geometry, arithmetic, map colourings and pattern recognition.

Outcomes:

• Use spatial skills to solve problems.
• Learn how to eliminate possible solutions to a problem.
• Identify if a number if even or odd.
• Finding patterns in sets of numbers.
• Use mental math to determine a sum to 20.

Fun with Fractions

We introduce and explore the world of fractions! Using visual and real life examples as well as fraction based games we make fractions easy and fun.

Outcomes:

• Describe everyday situations where fractions are used.
• Sort a given set of diagrams of regions into those that represent equal parts and those that do not.
• Represent a given fraction concretely or pictorially.
• Name and record the fraction represented by the shaded and non-shaded parts of a given region.
• Identifying equivalent fractions (Grades 5 and 6).
• Relating improper fractions to mixed numbers and mixed numbers to improper fractions (Grade 6).

Jury Duty

A crime has been committed! By exploring various areas of mathematics, such as logic, graph theory, cryptography 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.
• 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, algebra, and number theory.

Mathemagic

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:

• Finding patterns in sets of numbers.
• Mental math skills and applying these to concrete problems.
• Use spatial skills to solve problems.

Pentominoes

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 spatial skills to solve problems.
• Select 2-D shapes from a given set of 2-D shapes to reproduce a given composite 2-D shape.

Problem Solving

Explore the art of problem solving by investigating tiling problems, number games and graph theory problems.

Outcomes:

• Use logic to solve "hidden" math problems.
• Real life applications of math.
