There is only one special object associated with the holiday of Hanukkah, which is the menorah, a candelabra with 8 side branches and one central candle holder. This is one of the iconic objects of Judaism.
The Channukiah (Hanukkah menorah) is a candelabra that holds 8 candles to represent the 8 days of Hanukkah plus a 9th candle called the Shamesh which is used to light the other candles.
Any and all decorations are optional. Children might enjoy making paper depictions of menorahs, jugs of olive oil, and the like.
During Hanukkah we light a 9-branched candle holder (called a Chanukiah or Hanukkah-menorah). It is traditional to also play with a 4-sided top (called a dreidel). Giving chocolate coins to one's children is also traditional.
