This is not super fancy or anything! But if you wanted to use these animal flash cards, feel free.
Some male and female animals look exactly the same... BUT the way the document is organized, you'll see a baby, mommy, and daddy of each animal. The paper size that I used was a long skinny sheet of paper. If this is not really ideal for anyone, please just comment. I can make a new document where they're on 8.5x11 (standard size sheet of paper).
I won't do that yet because, so far, they're just for us!
I printed these, cut them out, laminated them, then cut them again. And I have Alexander match the 3 animals to each other.
