Pyramids can be made from a variety of products. Some pyramid projects require adult assistance or a higher skill level while others are relatively simple for young children to complete. Fold a small envelope or a sheet of construction paper into a simple pyramid. Use card stock or poster board, coat with glue and sprinkle with sand for added detail. Pyramid blocks can be molded out of plaster to build a realistic-looking pyramid or use sugar cubes, paper cups or plastic building blocks.
Paper mache can create almost any three-dimensional shape. Recipes can be found online or in craft books, and generally include flour, water and strips of newspaper. Have children make an animal or series of animals with a theme such as a zoo or farm. They can sculpt a plant or flower design and paint it using acrylic paint. Finish with one or two coats of a water-sealing product to help it last longer.
There are a variety of modeling compounds that even young children can use independently to sculpt objects. Clay dough can be purchased from many retailers or made at home. Other products, such as modeling clay, retain their shape better when dried and can be painted. Children can sculpt almost anything out of modeling compounds, including animals, people, food, flowers, trees, vehicles and buildings.
Have kids recycle objects to make a three-dimensional sculpture. Gather items from around the house or classroom such as broken toys and sports equipment, empty plastic containers or any other items that are not needed. Have children glue them together in interesting arrangements. To paint the sculpture, use a base coat of primer first to help the paint adhere to the objects.
