Making paper pyramids can be a fun children's activity at school or home as a follow-up lesson about Egyptian history. Paper pyramids also make cute containers for party favours, and large pyramids can serve as kids' playhouses. If you plan to make a lot of paper pyramids, first create a template that you can store with your art supplies and bring out when you need it. This eliminates the need for measuring and helps prevent mistakes.
Things you need
Draw a perfect square near the centre of the piece of cardboard. It can be as large or as small as you like, depending on your use. Five square feet works for a playhouse, while 6 square inches works well for smaller boxes and projects.
Make a small dot in the centre of each side of your square. Draw a line straight out from each dot, away from the square. The line should measure half the width of the square. For instance, if your square is 6 inches wide, make each line 3 inches long.
Draw a line on either side of the tip of each centre line to the corners of the squares. This should create one equilateral triangle on each side of the square, or four equilateral triangles total.
Sketch a thin rectangle on the left side of the uppermost triangle. This will serve as a glue tab to help hold the pyramid together. Turn the cardboard 90 degrees and do the same with each triangle so that they all have glue tabs on the left side.
Trace the outline of your pyramid template with permanent marker to make your lines stand out.
Cut along the perimeter of the marker lines with sharp scissors and store your template flat.
