Fold one piece of construction paper twice lengthwise so that you have three even sections. You will need one piece of paper per child for the crown itself.
Cut the paper down each crease so that you have three equal-sized pieces.
Leave two pieces as they are, and fold one of the pieces into three sections by folding it twice. The remaining two long pieces will serve as the base of the crown.
Cut the folded piece using the two creases as a guide.
Cut out the points of the crown by laying the three small pieces on top of one another and cutting a 45-degree angle from the midpoint of the shorter sides. Using the same midpoint, cut another 45-degree angle going in the opposite direction. The pieces should be square on one side and pointed on the other.
Overlap the two large pieces of paper by 1/2 inch to an inch, and tape or glue the pieces together.
Tape or glue the smaller pieces to one side the base. Attach the square ends to the inside, and allow the pointed sides to show above the base. The points should form a uniform zigzag just above the top of the crown base. The pointed pieces should be attached to the base near the top of the base to prevent the points from flopping down.
Use different colors of construction paper to cut out jewels or stars and distribute them evenly to each child.
Allow the children to decorate their crowns. Instruct them to write their names if they wish. Use metallic paint and paintbrushes for a shiny finish, or provide small items, such as the construction paper cutouts, flat-back rhinestones or small pieces of uncooked pasta that can be glued to their crowns. Allow the children to use glue sticks for paper pieces, or help them use craft glue for the rhinestones or pasta.
Set the projects aside and allow them to dry for two hours.
Wrap the base around the child's head and adjust the base so that it fits snug. Remove the crown from the child's head and tape or glue the base together at that point.
