These Trading Card Templates can be used for many different topics and subjects (from art to science). They come in two different sizes, in color and greyscale. I included the cards as a PDF-File, a PowerPoint that you can edit yourself and as picture files (.png).
I originally created these cards for my Math Card Game 'Numeramon'. You can find the game here, if you are interested:
