Trying to find the "create new card" function (as opposed to create new deck)

My high school students will soon be working with a couple of hundred 6th graders in creating Boise (Idaho) area species cards. I’m logged in and a tutorial says I should see a button to create new cards but all I see is a button to create a deck. Please direct me. Thanks,

Sorry for the confusion, @Josh_Pfiester ! You can create new cards from within a deck, so you must create a deck first. Let me know if that doesn’t help!
