AREA SLAM! is a great card game to practice identifying the area.
Setup: Copy on cardstock/tag board, laminate, and cut out each card.
Pass out all of the cards to the players. Player 1 chooses a card to play first and then everyone will determine the area. The person who has the correct answer will SLAM it down, then continue by looking at the next answer and so on... The player who SLAMS down all their cards first wins! Shuffle and play again!
