We took a piece of green construction paper and cut it in half. Each student had two pieces. Then we made it into a flap book and added the outside labels. I included half-dollars, quarters, and dimes.
On the inside, we cut between the coins to make flaps. For the quarter, for example, there were four flaps; one for each quarter.
We wrote the fractional part of a dollar that each coin represented, identified the value in cents, and named the coin.
We put it into the fractions section of our math notebooks. On the output side, we added a few statements identifying the fractional parts various coins represent.
