Math Card Game - Ordering and Comparing

Today in math we reviewed ordering and comparing whole numbers up through the 100 Billions Place. All we needed to play the game was a deck of cards, our game sheet, and a red pen. Once a digit was called, students wrote that number with red pen in whatever place value they wanted to. Once the digit was placed, they couldn't move it. After all 12 digits were called, students then compared and ordered their numbers with members of their groups. Their goal was either to create the largest possible number or the smallest number. What a game of risk, but yet a way to review concepts learned as well!
