This is a math review game following the "I Have, Who Has" format. This game is to review reading decimals and will help students with decimal place value. Because I teach decimals at the beginning of the year, I created a Halloween themed game to be festive. It's great to pull out to review this skill and only takes a few minutes, though at first it may take longer. You can also have the students write down the numbers on their cards on scratch paper and have them practice writing them in word form and expanded form. Before we play the game, I have students say their number to a neighbor so if they're unsure, their neighbor can help them with accuracy. There are multiple ways in which to use this games.
