Comparing Capacities

We had heaps of fun today finding out which cups held the most water. Our groups placed them in order from the cup that would hold the least amount of water through to the cup that would hold the most water. We then poured water in to the cups to check if our ordering of the cups was correct. We started by filling up the cup that we thought would hold the least amount of water. Which cup do you think would hold the most water? Comparing Capacities on PhotoPeach
