Teddy Bear Tea Party

Have each child bring their favorite teddy bear (or stuffed animal) from home.
  Have a tea party and invite the stuffed animals.  Set the bears at the little
 table using play dishes, have the children serve their bears pretend tea and cookies.

The Three Bears

Set up the three bears house (cave)....beds could be 3 different sized towels...3 diff sized
 chairs, bowls ect. and let the children act out the story "Goldilocks & The Three Bears."

Teddy Bear Fashion Show

Explain fashion shows to your children.  Feature a few children dressed in garments from
 the dress-up area to illustrate your explanation.  Ask each child to bring a teddy bear from
 home.  Make sure to provide some for children who don't have them or who forget to bring
 them.  Ask the children to dress their bears in a special way for a fashion show.  You can
 have the children dress the bears at home or you can provide clothes for them to choose
 from at school.  Remind them that the fashion can be just a new bow tie or hat or it can
 involve a complete outfit change. On the designated day, play soft background music and
 have the children describe the fashions that their bears are wearing.  Be sure to have
 awards for each bear with broad categories, like Most Unusual Hat, Most Unusual
 Outfit, Most Colorful Ribbon, Best Dressed, Loveliest Coat, etc.

Boo Boo Bears

What if your bear got hurt or sick? Set up a doctor table just for doctoring bears.
 Make sure there are plenty of bandaids, ace bandages, wraps, cold compresses,
 guaze pads, tape, injections (toy shots) stethoscope, ear looker, tongue depressors
 and rubber gloves. You would be amazed at all the stuff a hospital will give you
 if it is for educating little ones. It can't hurt to ask. The children will spend
a lot of time at this table so have lots of stuff.
