Problem Solving in Year 3

Today, Year 3 tackled an exciting maths problem solving task based on their current topic 'Natural Disasters'.
This it what they were asked to do:
We need your help. You are a seismologist working at the MET office in Exeter. We know that six countries in Europe are at severe risk of tectonic plate movement which could lead to a natural disaster. Can you use the fraction clues to figure out which countries are at risk and save hundreds of people's lives?
The children used their knowledge of equivalent fractions to help them. Below are some photographs of them hard at work.
