Follow the Yellow Brick Road is a fun way to practice adding tens to a 2 digit number. This covers the common core standard 1.NBT.4. This game is played a little like Candy Land. Students pick a card and add the tens to the number. If the answer is correct, then the card will tell you how many spaces to move. If you get a character card, then you have to move to that space on the board. First player to the end is the winner.
This game is also included in a bundle.
