It’s tight at the top

It’s shaping up for a close finish in Sumdog’s US National Math Contest this week.

Class 711, from Northwest Middle School, Pennsylvania, is just 25 points clear of the second-placed 5th graders from Shasta Lake School, California.

As they battle it out, though, they’ll need to keep looking over their shoulders – as the Keithley class, from Des Moines Christian School and Ironton Elementary’s 5th graders are hot on their heels.

With over 9 million math questions answered already, the contest closes at 8pm today.  Good luck, everyone!
