Cut a piece of corrugated cardboard into two 8-by-10 pieces. Make sure that the ridges of the corrugation run lengthwise. this will ensure that your skewers can easily be inserted later.
Use a paper cutter to slice one of the pieces of cardboard into six even strips. You should now have six 8-inch-long pieces of cardboard.
Separate the strips into sets of three and glue them together in a stack.
Push the skewers into the top piece of stacked cardboard. Leave about an inch between each skewer.
Place five Fruit Loops and five Cheerios on each of the skewers.
Line up the other stack of cardboard and insert the skewers in the corresponding layer of cardboard.
Glue each stack of cardboard to the 8-by-10 piece of cardboard remaining. Be sure that the layer of cardboard with the skewers is the top one, to allow the cereal pieces to slide.
Label each skewer with numerical values such as 1's, 10's, 100's, 1,000's, 10,000's and 100,000's.
