Scissor control combines grip, opening and closing, moving forward and watching the paper. A long shape can ask too much at once. Begin with short paper strips that need only one snip.
Use child-safe scissors and remain close. Demonstrate carrying them closed with the points down. On the page, a wide straight marker path is easier to follow than a thin line. A few calm cuts are enough for one day.
Children vary in when this feels comfortable. Offer help, avoid comparison and protect the pleasure of making something. The full creative pack includes graduated paths, playdough hand movements and open drawing invitations.
