Cultures throughout much of history built pyramids. Because of this, most children learn about pyramids several times over the course of their school years. A popular school project is for students to make model pyramids of their own. Making a realistic pyramid model for a class project can be easy and inexpensive.
Cut out four triangular cardboard pieces that are each 8 inches wide at the base and 12 inches tall. Hot-glue the sides of all four triangles together to form a pyramid shape.
Cut out a piece of cardboard that's 14 inches square. Hot-glue the bottom of the pyramid into the middle of this cardboard piece.
Draw several vertical and horizontal lines on each side of the pyramid with a dark brown or black permanent marker to imitate the appearance of bricks.
Drizzle glue over the pyramid and the base. Use a butter knife (or your fingers if you don't mind getting messy) to spread the glue into an even layer over each surface.
Pour sand over the pyramid and the base while the glue is still wet.
