Factor Fill is a 2-player dice game in which students practice identifying missing factors to multiplication problems. Players take turns rolling one die to determine the missing factor for various multiplication facts. Players search for the multiplication problems on the game board that is missing the factor rolled and place a colored counter on it. If no multiplication problem needs the factor that matches the player’s roll, then the player skips a turn. The first player to cover five boxes in a row – vertically, horizontally, or diagonally – is the winner. Two versions of the game is included. The first version (blue) is geared for students beginning to learn multiplication and contains multiplication facts from 1x1 through 6x6. The second version (red) contains multiplication problems which include 7, 8 and 9 as factors. This activity meets or exceeds the Common Core Standards and the New Jersey Standards for Student Learning and makes for a great class game or math center.
