This is the 3rd of the BIRD-O games. There are 25 different "BIRD-O"
cards as as well as the Words called, Answers Strips and an Identification Chart to help the student during the game. This game has 30 new color photos of birds and 10 review birds from Volume 2.
This is the Advanced volume. This does not mean that is is "harder," but that the birds are not as likely to be familiar to the students.
The other 2 volumes are in my TPT store as well as other Nature study games.
