The Nature Discovery cards from the Baby Einstein company are a great way for your little one to gain exposure to things in nature.
These flash cards are about 8 by 4 inches. They are made of fairly durable cardboard. On each there is a picture of something, as well as a matching word on the front. On the back of the card, there is a little information about what is pictured on the front.
These cards can be used for children of all ages. I have three sets of cards from Baby Einstein, and I think the Nature Discovery set is my least favorite- or at least the ones we use most seldom. The pictures on some of these cards (like galaxy, wetland, and planets) tend to be a little abstract for my two year-old.
While Baby Einstein makes a lot of great products for small children, I can’t highly recommend this series of discovery cards. Perhaps older children would like these, but may be a little bored with flash cards.
