Place Value SLAM! is a great card game to practice counting base 10 blocks.
Setup: Copy on cardstock/tag board, laminate, and cut out each card (each card has a value and base 10 blocks picture).
Pass out all of the cards to the players. Player 1 chooses a card to play first and then everyone will count the base 10 blocks. The person who has the number value of the blocks will SLAM it down, then continue by looking at the next base 10 block and so on... The player who SLAMS down all their cards first wins! Shuffle and play again!
