Cardboard Dinosaur Skeleton Frame

You will need

• Cardboard boxestwo or three broken-down flat boxes; clean, not chemical-storage boxes

  Use boxes that held food or household goods, not chemicals; wipe the inside surface and remind the child not to put cardboard in their mouth.

• Masking tape or painter's tapeone roll; joins pieces and marks the floor spine line
• Scissorschild-safe; adult cuts any thick double-wall sections
• Ruler or yardstickoptionalfor checking proportions; a length of string works too
• Washable markeroptionalfor the child to sketch bone shapes before cutting
• Reference picture of a dinosaur skeletonoptionalprinted or on a screen nearby; triceratops or stegosaurus work well

Steps

1. 1

   Lay out the building field

   Flatten the boxes and lay them on the floor. Run a strip of masking tape in a gentle S-curve about three feet long — this is the spine. Tell the child, 'Paleontologists lay out the bones in order before they study them — let's do the same thing.'

2. 2

   Start with the skull

   Ask the child to tear or cut a skull shape from the cardboard — roughly an oval with a pointed snout. There's no wrong shape. Tape it at one end of the spine. If they have a reference picture, put it where they can see it without reaching.

   Tip: Tearing cardboard along the corrugation gives a naturally rough, bone-like edge.

3. 3

   Build the ribs and legs

   Encourage the child to cut long curved strips for ribs and place them symmetrically off the spine. Legs can be simple rectangles with a notch cut for the knee joint. Step in only to tape sections that keep sliding — let the child direct the layout.

   Tip: Folding a strip in half before cutting gives two matching pieces at once.

4. 4

   Add the tail and feet

   The tail is often the longest part — prompt the child to count how many segments a real dinosaur tail might have and cut that many short strips, slightly tapering toward the tip. Feet can be three-pronged, cut from a single flat piece.

   Tip: If the tail runs off the cardboard, add a second sheet butted up next to the first.

5. 5

   Tape and review the skeleton

   Once the child is satisfied with the layout, go around together and tape the major joints so the skeleton can be picked up in one piece if you want to hang it. Ask the child to name each section. Photograph the finished skeleton before moving on.

   Tip: A low-angle phone photo makes it look like a real museum exhibit.
