Why it helps

Cutting cereal-box cardboard gives the hands more resistance than paper, which builds finger strength and the small muscles inside the hand. Slotting the pieces together asks both hands to work as a team and takes motor planning to figure out how they fit. Building a structure that stands on its own also practices visual motor skills and focus.

Steps

Open a cereal or cracker box and lay it flat. Use markers to draw several strips about an inch wide and a few simple shapes, like squares and circles.
Ask your child to cut along the marker lines with scissors.
Cut two or three slits into the edges of each piece, about half as deep as the strip is wide. You can do this part or share it.
Show your child how to slide two pieces together at their slits so they cross and hold each other up.
Challenge your child to keep linking pieces to build a structure that stands on its own, like a tower or a creature.
Your child can hold the structure steady with one hand while the other pushes each new piece into place.

Safety tip: Supervise scissors, and handle cut edges gently, since thin box cardboard can give paper cuts.

Make it easier

Draw fewer, wider strips, about two inches across, so there are fewer cuts and the slits are easier to line up.
Cut the strips yourself and let your child focus on sliding the slits together.
Make the slits a little wider so pieces slide in without much wiggling.

Make it harder

Challenge your child to build a structure taller than a water bottle that stands on its own.
Cut a few circles to use as wheels or windows, which takes more turning of the cardboard.
Build something you pick together, like a bridge between two books or a house with a door.

What to watch for

Notice how the helper hand turns and holds the cardboard while the scissors close. Stiff box cardboard asks that hand to do a lot of the work.
Watch how your child lines up a slit before pushing. Some kids turn the piece to match first, others push and wiggle until it fits.
If the scissors keep getting stuck and frustration builds, cut the pieces yourself and save cutting practice for paper.

Where this helps in daily life

Squeezing scissors through stiff material and lining up two pieces to slot together use the same hand strength and planning kids need for cutting out school projects and putting together building toys.
