Thicker is Better

There’s nothing to hold onto when you’re following a thin one.

Cutting line, that is.
So many children destroy small pictures when the stimulus boundary is only a thin black line. It seems almost inconceivable that the outline has any bearing to the placement of the scissor blades. You might as well have asked them to slice a strand of spaghetti in half… lengthwise.
When first instructing young children in cutting, thicken the stimulus line to the width of a broad tip marker or the equivalent of a 30 point line made on the computer. Then ask the children to cut right down the middle of the black line so that black is visible on both sides of the paper when it’s separated. You can even draw a pencil mark through the black line so children know what you mean.
Then, once they’ve actually bisected the paper, place the two sides next to each other. Point out whether black is showing the full length of the cut on one side, and then the other.
As children understand the goal of the activity, the width of the line can be thinned.
Pair this strategy with Lead-In/Lead-off Lines. Your children will be cutting more accurately in no time!
