Like most people, you probably have enough of your childrens ‘artwork’ to fill the national treasury.  Too precious to throw away and too much to do anything with!!  When my children were starting to go to pre-school, elementary school and on up this is how I solved the problem.  I purchased a plastic bin for each child.  The long and not too deep variety, say 3′ by 8″ or so deep.  I stashed these on a top shelf in their closet or under the bed.  Anywhere that would make sense and out of sight.  Each time they came home with their beautiful creations (which was almost every day!), I would determine what was worth keeping, on the back I would record the month and year, the school, the grade they were in and their age.  I know, some of that seems redundant, but really, when they pull it out some day, who wants to do the math as to “how old was I when I made this?”, it’s all there.  Takes about 30 seconds. Then I would place it in the bin.  In the bin also goes report cards and those ‘welcome to the new year’ letters teachers would write. Essentially anything that was sentimental and worth saving.  Here is the key.  If you do this from the beginning and don’t go through it, each piece placed on top of the next, you will have a chronological history, so to speak, of all your childs elementary years.  I plan on giving my children their bins some day and what they do with them will be their business, but I am sure they will have fun going through memory lane.
