These Multiplication Houses teach the multiplication facts in a really creative way. There is a house for each number from 1-12. You print out the houses and cut them out. Then for each square with a number you cut around them so they open like a window.
Mount the house on another sheet of paper, gluing all except the windows. We liked using different colors of construction paper. Behind each window the kids write the answers to the multiplication fact. For example, if it is the house of threes they multiply each number by three and write that answer behind the window.
