If you know their names you could paint or write their name on a Christmas ball decoration and add some glitter.
Chocolate bars - measure the wrapper and make your own on the computer with a cute graphic, class name and year.
Buy some cheap little angel decorations and wrap individually in a circle of tulle and tie with curling ribbon.
Little bottles of bubble mix.

I took a 2 pieces of light brown felt, laid them on top of each other, cut into 4 pieces(actually 8 pieces in stacks of 2). Cut out a deer shaped head and horns, simple shape,hot glued the two pieces together, adding a red ribbon hanger to the top in between layers. I put 2 wiggle eyes and a red pompon for the nose, and a red bow on top of head. I then cut a slit in the back of the back layer and slipped in a chocolate santa and a candy cane. We had our party at school today and the kids loved them

here is 2 ideas I did and both are so fast and easy. at walmart or craft supply place get a pkg. of wooden wheels paint them a solid color, then I painted simple snowflakes or just start by the center hole and paint a small circle and go bigger and bigger. they turn out to look like a pinwheel design, anyway take a dowel and shapen the end just to a flat point then cut they dowel off about 2 or more ins. long and put it thru the hole. it makes a top that spins so easy. the other idea a sled w/ candy seat and santa. two candy canes make the sled runners then hotglue 2 minature candy bars toward the back part of canes to make santa seat,and 1 minature makes the back of the seat, glue a choc. santa standing up on the seat, 2 small choc. square bars glued in front of santa. this was easier than it's sounds. the choc. santas are 1.00 for a pkg. the square bars were at wal mart and has to santa or other sayings on them for 1.50a pkg. the whole thing costs about .33 each to make and are so cute, the tops, I made I sold for 1.00 ea. and sold about 30 in an hour.
