I grabbed a naked frame (plain/unfinished wood) that I had picked up at Micheal's for about $1. Set the frame on some old paper ads in the kitchen on the floor. Gave Widget some markers and told her to decorate the frame.
I had images of a rainbow colored frame dancing in my head-since she is REALLY into rainbows right now, and it would take a little more time-but instead she wrote some letters and drew some swirls on the frame.
I loved this project, even if it didn't turn out the way I had imagined. It was cheap- only about $1 for the frame (which I already had on hand), markers on hand, newspaper/ads on hand, and Widget on hand...that's a total of about $1 for the entire activity!
Widget really wants to try typing, so I told her I'd let her have a turn on the 'puner' (as she calls it). Please enjoy the typing's of a preschooler:
