CHECK OUT THE PREVIEW... THE THUMBNAILS ARE NOT GREAT!
Expanded Form Thousands SLAM! is a great card game to practice identifying expanded form and standard form.
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 Expanded Form Thousands. 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!
