I was a teacher and always wanted non-labeled school supplies because we used community supplies (in grades 1-3!). When we asked for pencil boxes, we would have 10 or so filled with markers only. If kids wanted to use markers, they would grab a box to use, then return it to the community supplies area. So, no "lucky kid" was getting someone else's stuff, it was all shared.
This works well for younger kids for quite a few reasons. First, it teaches children respect for the materials. We must take care of the materials because everyone has to use them. Kids feel the pressure from their community to take care of the materials (good peer pressure). That way, Johnny can't say, "Well it's my eraser and I can destroy it if I want to," and then have no eraser for the remainder of the year. Also, 10 sets of community markers can be replenished when they wear out (becasue the teacher will have the other 20 sets in storage). Each child having their own markers means that when the brown runs out, your child has no brown. With colored and regular pencils, teachers or students can sharpen pencils for the whole class at a designated time, rather than students constantly being distracted by sharpening and or waiting for other kids to sharpen pencils. Community materials don't get lost in someone's desk. No one fights over the pretty princess pencil. Kids also don't get distracted by the mirade of materials in their desk (playing with materials). Also, parents are more likely to buy plain old materials rather than flashy ones when they know their child won't end up with what they buy. School materials are for doing work at school. Learning should be the fun part, not flashy materials. Fancy pencil sharpeners and such just distract kids. As for folders, I always separated the colors and made folders for each purpose the same color. For example, everyone's "take home folder" was orange. That way, kids that maybe don't read so well don't have trouble figuring out which one is the "take home" and which is the math folder. Finally, materials always lasted longer when they were community. A child might start out the year with 100 pencils and they would be gone mid-year. Then what? Using community supplies, the teacher can keep the stock and monitor the community supplies. If the class is running out of pencils before they should be used up, maybe we need to clean our class, move all the furniture and find pencils! Or, maybe we need talk about where all of our pencils are going. Should a pencil leave the classroom? Also, kids know more about what their peers are doing than the teacher does. If kids are made responsible for the community materials, they start to talk to their friends that are destroying or taking materials out of the room because they need those materials too. Good lessons in responsibilty and living in a community.
After a few years of this kind of situation, many 2nd, 3rd, or 4th graders are much more appreciative and understanding of what it takes to have their own school supplies. They have been a part of a classroom where everything has a place and during clean-up time we put things back in those places so we can all find them. Often this transfers to their own materials. They make a place in their desk for their pencils and make sure pencils make it back there so that they can find them later. Or, they utilize down times to sharpen all their pencils so that they always have a sharp on ready.
Now, it doesn't always work this way exactly, but those are the reasons I used community materials. My suggestion would be to buy the plainest, cheapest materials you can find. That's probably what the teacher would prefer anyway! Allow her to personalize through the clothes that she wears, or a folder with stickers after she recieves "her" folder for the year. Remember, school isn't about being flashy. It's about learning and expressing your personality in ways that don't make folks that can't afford it feel at a loss. Hopefully her teacher will be a good one who encourages children to express their personality and help decorate their environment at school through arts, crafts, and writings! Hope this helps and best of luck in the new school year!
