Here are a few online map quizzes to try!
Bodies of Water Map Quiz - This one has almost every single body of water you need to know for your map quiz and some extra ones. You only need to know the ones on your word bank for the quiz. You may struggle with the ones not on your map quiz word bank, but think about the names and try and figure out where they go.
Continents and Oceans Map Quiz - Pretty basic stuff, but make sure you get 100%! The Southern Ocean is added by some as the 5th Ocean of the World.
