I love plastic baggies!  They are such a helpful item to have around the classroom.  Each year I ask the kids to bring in a box of baggies.  I have half the class bring small baggies and half the class bring gallon size baggies.  Do you already have a list of things you use baggies for?  If this sounds crazy to you, it isn't!  I know other teachers do the same thing and would agree that baggies are so helpful.

Here are some (and only some) of the ways I use baggies in the classroom:
-putting projects in to take home                                    
-students store their classroom money in them
-girls often ask for something to put jewelry in and I hand over a baggie
-using them for fraction strips, flashcards, etc in math
-vocab cards can easily go in them and be safely stored in backpacks or desks
-I put work in the baggies for helpers who are taking things home (separating book orders, cutting laminated materials, etc)
-putting extra clay in so that it doesn't dry out between projects
-when sick students are absent and sibling/friend/parent is picking work up
-taking seedlings home at the end of the plant unit
