For Teenie I chose some phonics sheets and math concepts that she is currently working on, and also some things that she is having issues with such as a skip counting chart. For Sonshine I found liquid measurement conversion charts, prime and composite numbers chart and Roman numerals. I have found a great deal of information just by googling "free mini office printable" or by typing in what I was looking for specifically i.e. "printable periodic table of elements." The beauty of these mini offices are that you can make specific ones for specific subjects, or if you are lazy like me, just make one that has all of the general information that your kid might need. Either way it's win-win, because eventually after referring to the information and seeing it over and over, the kids will start to memorize it!
All you need to make these is 2 new or used file folders (or more if you need a bigger office), a glue stick and some printable (check out the links at the end of this post)
I used 3 folders per kid.
Add your information and you're good to go. (Cute kid cameo apperence by Sonshine).
Here's a close up of the mini office I made for Teenie.
Laminating will make them last longer, but is not necessary. You can also use strips of clear packing tape (get it from the dollar store) to "laminate" as well. Kids can them personalize the front cover by using stickers or markers.
