Here in fairytwinland, we like to make as many of our book displays as interactive as possible. Any excuse for play, imagination, ownership, and creative thinking, amirite?
A couple years ago I made a magnetic poetry set for an "animal poetry" display (typed in word doc, printed, laminated, cut, added magnets), so this year I just busted that out again with our old flannelboard, covered the table in black, and emptied the nonfiction shelves of all the coolest poetry for kids the 800s could offer.
May be too late in the month for you to use for Poetry Month this year, but please! So easy! So fun! So poetry! Use away!
