The food pyramid is a tool used to teach healthy eating practices, but simply looking at a food pyramid may not be enough. Building your own, however, makes studying the pyramid an interactive activity. You can make your food pyramid as large or as small as you want, but the bigger you make it, the more room you have to write or draw on it. Making a three-dimensional one gives you more space than ever before --- instead of just one flat triangle, you have four complete sides on which to draw pictures or write descriptions of foods in their appropriate categories.
Draw a square on a piece of card stock. It can be any size you want --- the square is going to be the base of the pyramid.
Draw four triangles coming off of the square. Each side of the square is the base of another triangle, so each one should be pointing in a different direction. Measure with your ruler to make sure that the triangles are all the same size.
Cut out the shape you created. Leaving the triangles attached to the square base, cut out all the excess paper around them. The end result should look like a four-pointed star.
Fold each triangle up at the base and crease the fold. The four points should meet at the top, forming a pyramid. Tape the sides of the triangles together to hold them in place.
Draw three horizontal lines on each side of the pyramid, dividing each side into four sections. Draw a vertical line through the centre of the middle two sections, so each side of the pyramid now has six sections.
Write examples of foods in the appropriate food group spots. For example, write "bread" and "cereal" in the bottom section for grains, or "candy" in the top section for sweets and fats.
If your pyramid is large enough, draw pictures of foods or attach photos of foods cut out from magazines.
