April is . . .

April is National Mathematics Awareness Month.  The theme is SUSTAINABILITY and some ideas for learning and doing may be found here (including a rich selection of essays).
April is National Poetry Month.  One of the month's special events is a poetry contest (open to all) sponsored by the Arlington Library.  Poems for the contest are to be formed from stacked titles of CDs or books and then photographed for display.  For example:

A Mathematics Spine Poem

 A mathematician's apology

What is mathematics?

Mathematical magic show

Mathematics for the million

The world of mathematics

Mathematics:  the man-made universe
