This is something I had posted over in Frugal Living. We did this for Christmas for my son's 3rd grade teacher and she loved it. She said was gonna do one for her son's teacher! If you want to do a little more, you can do this mug and also a gift cert. in a card.
The following all goes into a mug and you attach the following note:
Teacher's Survival Kit
Tea Bag- To remind you that you're "TEA-RRIFIC"
Paper Clip- For keeping things organized
Rubber Band- A reminder to stay flexible
Bandaid- To mend hurt feelings
Tootsie Roll- To remind you how sweet you are
2 Pennies- So you have the "cents " to realize how valuable you are
Mint- To remind you that we're thankful for your commit"mint"
Crayon- To color your days cheerful and bright
Lifesavers- To remind you that you're appreciated a "hole" lot
Just put it all in a cellophane wrap in the mug.
