I can be pretty disorganized, but I do have a few ideas to share!
My 'Teacher Area'
I don't have a large nice shelf behind my reading table/next to my computer... I just have a sundry of organizational things all stacked up on top of each other, which has actually worked out great!
Reading Table
Don't have much storage space around your reading group area? Find some hanging shelves (typically used in a pantry) and hang them under the table. This hanging shelf was purchased from Lowes for around $6.00.
Student Letters and Drawings
My students give me drawings and letters constantly. I feel bad throwing them away and I am unable to hand them up around the room due to space constraints. So I have come up with a 'scrapbook'! I have a notebook filled with page protectors, and whenever I get a little letter I stick it inside. When students ask where I put their work, I just say, 'In the scrapbook'!
Lunch & Computer Cards
I don't know about your classroom but I could never find my stack of lunch cards when it was lunch time, they were always under a stack of papers somewhere! So this year I started using a Target dollar section pocket chart with number labels, and it has worked wonders! One of my students job is to organize these cards each day behind their classroom number. (I wrote their number on the back of the card in sharpie) The pocket chart behind this one is the same thing only with computer cards (Log-in) info. My two 'computer consultants' organize those each time we go to computer lab.
Extras Drawer
This seems simple, but it has really cut down paper clutter! I got this idea from my student teaching cooperating teacher. When my paper passers have any extra papers they just stick them in this drawer. This way if I have a student that has 'lost' homework, another teacher needs another copy, etc you can just go to this drawer!
Editables
If you are anything like me, you have to snack! I keep all food and food related items in one area. A desk works great to get a fridge up off the floor and provides a little storage for silverware, plates, cups, etc.
Turning in Papers
This is a set of cheap plastic drawers that are spray painted and paper modge-podged on the inside. It doesn't look as stelar as it did in its glory days, but it still does the trick! When the kids are finished they put their work in whichever drawer I announce at the beginning of independent work. When my aid comes in she knows to grab from these drawers.
Magnetic Letters
I have found that tupperware is the best thing to use to organize letters! They are in sets so that two kids will share one box. It is easily gotten out, put away, and stored.
