Classic memory card game featuring dinosaurs. Extinction is one of my Science Memory games.There are 6 pairs to choose from, 12 cards in all, presented here in Power Point.The first slide will show all the dinosaurs and their positions. You may keep this slide up for however long you want the player(s) to view it. Click next and they will be covered up with numbered cards.An initial click on a card will let the player(s) get another peak at what is underneath it before it gets covered back up. C
