Have a list of the birthdays of the children in your group. Make a chart either with numbers (1-31) or the months of the year. Have the children put a sticker on the appropriate date or month that applies to them. See which has the most!
Play dough Cakes
Provide your children with play dough and real unused birthday candles.
Put muffin liners in an old muffin tray. Have the kids fill them with different colors of play dough and put candles in them. They can serve them to the birthday child!
Use wrapping paper, ribbons, bows, and tape to create collages with. You may even have the children cut up the items first and then create the collages at a different time.
Print out a large picture of a candle. get the child to color in or paint the candle. then cut out where the flame is. put contact over the hole and get the child to cover it with glitter.
