"Organize" school flyers by storing them as pictures on your phone
With all the notes that come home from my children's school (both electronic and paper) I find keeping the email attachments or taking pictures of the fliers to keep on my iPhone helps me keep track of it all without having to keep all the papers. Field trip notes, school assemblies, sports and group schedules are just a few of what I currently have.
(I have also used the same idea to keep track of blood test results that I may need to refer back to with my husband's recent health issues.)
Ah, the "paperless backpack." Wouldn't that be lovely?
One low-tech solution is to keep a clipboard in the kitchen (or other common area) for those sorts of notices. I also try to transfer the info into my calendar right away so I've got the details (including phone numbers and locations) in a workable form.
How to do you stay on top of notes from school?
