This is a tic tac toe game with a DIFFERENCE -- the players must correctly answer a question to be able to place a marker on the board. There is an Identification Chart to help the student find the name and group of the 100 animals in the game. They are in 10 groups: Mammals, Birds, Reptiles, Amphibians, Fish, Arthropods, Echinoderms, Mollusks, Cnidaria, and "worms."
There are many nature study or science games in my TPT store --
Crossword, Word Search, Bingo, Rummy, Concentration, Sorting,
Tic Tac Know, Dominoes and Board games.
