I just compiled a list for a friend and decided to list it here for future reference. I've found many of these lists from different blogs and online friends. Also, I came up with some of these ideas on my own. :)
These are the activities, bins, websites, kid's sites, and different blogs that I frequent that help me to homeschool with preschoolers and toddlers in the house. They are my saving grace. I hope they help others and I may add to them when I have more time.
Here's the list of boxes...
The treasure box (it's full of polished stones and "gems", a magnifying glass, a pair of tweezers, and a tray to collect their "treasures")
The clothes line box (old fashioned clothes pins, a clothes line, and play clothes to hang up)
The clip box (full of chip clips, regular clothes pins, tongs, and little fuzzy balls to pick up)
Hammer and nails box (golf tees, styrofoam disks, styrofoam plates, and a toy hammer to "pound nails")
Look how happy that little guy is...
Pipe cleaners and fuzzy balls box (title says it all.lol)
Bead box (has beads and string for making necklaces)
Cowboys and Indians box (has little plastic pieces and Kapla blocks to play with)
Foam sheets, stickers, and sequins box (has glue and scissors to make things with)
A playdough box
A science box (has magnets, metal, seeds, and do-dads.)
There are a few blogs out there that I've found some good ideas on also.
