While cutting and using scissors is an important skill for a child to develop, it is also very important to assist with printing. The open and close motion of using scissors works the same little muscles of the hand that a child needs for holding a pencil to print.
Using scissors also incorporates the helper hand - the non-dominant hand that holds the paper. The helper hand is necessary when printing to stabilize the paper so the working hand's job is easier.
See how the child is holding the scissors and correct their grasp if non-functional. Below you will see the "correct" grasp for scissors, however, using the thumb and index finger is also acceptable.
Have the child engage in activities that promote hand strength and scissor skills. These activities can include using tongs to pick up and sort small items or make confetti by punching holes in paper using a single hole punch.
Remind the child to use a "thumbs up" grasp so they are always cutting away from their body.
Remind the child to "glue their elbow to their body" to promote a stable body posture.
Change the materials you are using to cut. Begin with resistive materials such as straws and PlayDoh. Progress to thick paper such as cardstock. These materials allow the child to focus on the scissors rather than holding up the paper. Once the child has masters cutting lines and shapes with thick materials, progress to regular paper.
When introducing paper, use thin strips to allow the child to hold it easily.
For more complex shapes, the helper hand has a larger role to play. Practice bimanual coordination activities with the child such as lacing or beading to practice having the hands engaging in different tasks.
