Title: Global Math


This project uses math as a unifying tool to investigate and understand our shared world.  Activities are designed to appeal to a broad range of students and ability levels.  They can also be adapted for non-math teachers.


This project includes several collaborative activities throughout the school year. Students use basic secondary mathematics to observe symmetry in their surroundings, compare regional temperatures, model population growth, gather statistics about their communities and measure the size of Earth.


The goal is to use mathematics as a common language to facilitate investigation and collaboration.

Possible classroom activities


PICTO EQUATIONS CHALLENGE: Formulate equations represented by pictograms. Share the designs challenging the rest of the participants to solve them.

LIFESTYLE STATISTICS - from different classrooms create a common survey of quantitative data about their community and school (ex. How many languages do you speak?). This data is shared and analysed.

GEOMETRY IN YOUR COMMUNITY - students post and share photos from their community that illustrate geometrical properties and principles.

HOW'S THE WEATHER - students collect and compare monthly temperature data for their region. Depending on the level of the students we can use linear or sinusoidal models to compare.

WORLD POPULATION - students gather data on our changing world population. Depending on the level of the students we can use exponential models or systems of linear equations.

EARTH MEASUREMENT - based on the experiment by Eratosthenes, students use the shadows of meter sticks measured at the same time around the world to calculate the size of the Earth.

Expected outcomes

Sometimes the product is a joint publication, an online exchange, the creation of a gallery of photos, or creation of a website

Group contributions to others and/or the planet:

The project helps students understand that mathematics is an important unifying tool for understanding our planet. The language of mathematics is culturally neutral, and is thus an ideal way to investigate, explore and share our world.

Goal 4: Ensure inclusive and quality education for all and promote lifelong learning

Part of quality education is becoming comfortable with mathematics and STEM and understanding how these are tools for understanding our world.

Goal 5: "Achieve gender equality and empower all women and girls"  Women are under-represented in STEM fields.  This project creates ways for girls to participate equally and in a forum that is collaborative and project based.  

Goal 13: "Take urgent action to combat climate change and its impacts."  Many of the activities focus on environmental issues like temperature change and population growth.

Goal 16: "Promote just, peaceful and inclusive societies"  Anytime students have an opportunity to collaborate with peers from another culture you are addressing this goal.
