I picked up this matching game because I liked the pictures with words.  I was happily surprised to discover a folded mat to play on in the box.  It definitely needs laminating, but how can you beat an activity like this for a dollar?

Also, I had recently seen an idea for having kids weave ribbon through a wire shelf rack.  Looks like a great fine motor activity.  Guess what- Dollar Tree has those wire racks.  I wish I could find the original source of this idea, please let me know if you know of it.  I also purchased 3 yard rolls of wired ribbon (in Christmas colors) for a dollar, but I found these at Michael's.

Update:  The source of the idea was the wonderful Prekinders site.
