## Mission 4: Measure Under Pressure

| Publish on September 12, 2018

## Travel to ancient Greece and use your knowledge to help the mathematician Eratosthenes.

The Netmath missions are problem-solving activities that stand out from the rest of the content offered on the platform. More complex, these activities immerse the students in an exciting adventure connected with the history of mathematics. Their mission? Restore all the math knowledge to help Alfred save the great city of Mathlantis threatened by Dr. Chaos.

The students find themselves outside the Library of Alexandria, where the Greek mathematician Eratosthenes is trying to measure a globe. They are seeking a measuring tape, a device with units of measurement on it. With this simple instrument, the world of mathematics can take another giant step and Eratosthenes could perhaps measure the entire world!

To complete this mission, students will have to calculate perimeters, areas, circumferences, and distances.

The missions are accessible for the 6th year of primary school through to the 3rd year of secondary school. However, they are not all available to students from the outset. Instead, students must unlock them by completing a set number of activities with a grade of 100%.
