Current Math Teachers at Play and upcoming Carnival of Math

by

balloonsYup, the title pretty much sums it up!

Math Teachers at Play #14 is up at Math Mama Writes… and, as always, is full of great posts.  One of my favorite is  a chart illustrating how few quadratics have integer roots.  It’s a little daunting (although I suppose you can increase the number by considering negatives).

Speaking of Carnivals, there will be a Carnival of Mathematics #56 next Friday up at Reasonable Deviations.  The official Carnival submission page doesn’t seem to work anymore, but there are instructions at the link above to email or post a submission.
