Draw the outline of the picture on the paper (if the kids are small) with a white crayon.
Use any school white glue--do not use glue sticks; they will not hold the construction paper.
Place the glue on the paper for the kids and do not do the whole paper, just small portions at a time.
Have the kids work in groups of five or six at a table.
Give the kids a handful of construction paper squares and they will create beautiful pictures.
