While the dough chills, help your child trace the soda carton onto thin cardboard. First, trace a long side to create a template to use for the front and back of the house, making it as long as the carton but 1/4 inch less high. Then trace an end to make a template for the peaked sides of the house, as shown--use a ruler to draw diagonal lines from the top corners of the side panel to the top of the carton handle.

Finally, cut out 2 cardboard pieces for the roof, making each one 2 inches wider than the carton and 1 inch longer than the length from the top of the handle to the top of the front wall. Tape the roof pieces together lengthwise, leaving a slight gap between them.
