In the Mishna, Rosh HaShanah (the first of Tishrei) is refered to to be the birthday of the world. This is a great time to think about what our wishes are for the world in the upcoming year.

It can be interesting to make cards with greetings and well wishes or a wishing well to toss in small change for tzedakah and wishes.

Make a poster of a cake and numerous paper candles. Use the candles to write out and share well wishes.

Organize a birthday party-- with party games and a cake.
