Creating 3-D shapes is a fun craft for children of all ages. It helps younger children look at shapes in a unique way and understand how all aspects of the shape fit together. For older children, it can be the first step toward making a creative piece of art. A 3-D pyramid has endless possibilities as a craft project.
Draw a square in the center of the piece of paper with 2-inch sides. Mark the 1-inch point at the center of each side of the square.
Make another mark on the paper at the point exactly 2 inches above each 1-inch mark. This will be the point of the triangular-shaped sides. Using a ruler, draw a line from this point diagonally down to the corners of the square, creating four triangles, one on each side of the square.
Cut out the shape you have just drawn. Do not cut the square out. Keep it attached to the triangles.
Fold each triangle inward along the line drawn as the side of the square. Each side should match up with sides next to it.
Tape the sides of the pyramid together along the seams, so that they meet to make a point at the top. Pinch the edges together to keep the tape secure.
For a fun art project, draw patterns, shapes and hieroglyphics on the inside of the pyramid before taping it together. Then cut a small door in one side so that you can look through the door to see the decorated interior.
