Have your child practice cutting construction paper. If they're starting to cut, just have them make random cuts however they would like. If their motor skills are a little more advanced, have them cut simple shapes like circles, squares, or even snowflakes.
Scissors, paper.
God shapes us.
Cut with scissors.
He cuts off every branch in me that bears no fruit, while every branch that does bear fruit he prunes so that it will be even more fruitful.
John 15:2 (NIV)
