Super easy way to have 2nd or 3rd graders physically make each of the multiplication facts. They roll two dice (two different colors, one color for rows and the other color for columns) and create the array using stickers or rubber stamps. Sometimes having them use graph paper helps keep the rows and columns lined up. Also, since a regular die only goes up to 6, you can use dice that has 10 faces. Another options would be to cover the numbers on the regular dice with blank stickers and write in your own numbers.
