Give the student four pieces of paper of the same size. Tell the student to:

1. Fold one piece to show halves and color one half of every piece.
2. Now fold one piece of paper again to show a fraction that is equivalent to one half and has four as the denominator.
3. Fold another piece to show a fraction that is equivalent to one half and has six as the denominator.
4. Fold the last piece to show a fraction that is equivalent to one half and has eight as the denominator.
