These are sheets of ALL European Euros. I have included both colored and greyscale versions. These can be used as rewards for games, participation, or currency for a class store.
All the Euros are actual size down to the millimeter (the larger denominations are longer and wider than the smaller ones)! It includes bills for €5, €10, €20, €50, €100, €200, and €500. It is also nice that students are able to see currency from another country and your class can talk a bit about currency conversions as well.
I recommend printing them on colored paper corresponding to the Euro color (for example printing €20 on blue paper, €10 on red, etc.) and laminated them as well so they last a bit longer. Students really seem to enjoy collecting these throughout the year. I've used them to give out for participation (speaking the target language in class, answering questions, handing back papers, etc.) for all grade levels then collect them at the end of the quarter for a grade.
I test printed all of these and they look great (no margin or format problems). I recommend printing these instead of making copies as they do lose some quality when photocopied.
