Why it helps
Tearing thin cardboard takes a strong two-handed pull, which wakes up the hand muscles used for pencil grip and scissors. Turning each rough piece to line it up with the slit, then pushing it through, builds finger control and planning. Your child also learns to push hard enough to post the piece without sliding the container, which builds force control.
Steps
- Before play, use the scissor tip to cut a slit about 1.5 inches long in the center of the container's plastic lid. Put a small piece of masking tape over each end of the slit so it does not tear wider.
- Cut thin cardboard from a cereal box into strips about 1 inch wide.
- Ask your child to tear the strips into pieces about the size of a stamp, using both hands. The cardboard takes a strong pull.
- Snap the lid on the container. Ask your child to hold the container steady on the table with the helper hand.
- Ask your child to pick up a piece, turn it until it lines up with the slit, and push it through with the fingertips.
- Keep posting until all the pieces are inside. Then pop off the lid, pour them out, and play again.
Safety tip: Keep the scissors with you after prep. Torn cardboard pieces are small, so stay close and keep them out of the mouth.
Make it easier
- Snip the edge of each strip every inch so each tear has a starting point.
- Make the slit a little longer so the pieces slide in without much turning.
- Post the pieces through a wide opening first, then try the tight slit.
Make it harder
- Ask for long, skinny pieces that must be turned just right to fit the slot.
- Post pieces using only the thumb and pointer finger, with the other fingers tucked in.
- Color one side of each piece and post them all colored side up.
What to watch for
- Notice how your child turns each piece to match the slot. Turning it in the fingers before reaching the slot shows good planning.
- Watch whether pushing makes the container slide. If it does, the helper hand may need to press down a little more.
- If the rough edges of torn cardboard feel scratchy, let your child wear a thin glove or tear paper instead.
Where this helps in daily life
Turning a piece to line it up with an opening is the same planning kids use to fit a key in a lock, put a puzzle piece in place, and push a library book into the return slot.
