I recently purchased the Safari Ltd Dinosaur Skulls Toob. When I finally opened it, I panicked a bit, because the toob didn't have a informational card, and I don't know dinosaurs at all. I pulled the contents card from the Safari Ltd website and began slowing creating these cards. Each "skull" has two matching cards, a picture of an actual skull and a picture of the completed skeleton. When the student becomes proficient at naming and matching all the animals, the cards can be made into 3-part ones.
