Best of “Let’s Play Math!” in 2007

Meanwhile, I am hiding in my den, indulging myself in a sort of blogger’s nostalgia. Some of the following posts got a lot of attention when they were published, others not so much. Topics range from preschool to high school, Captain Kitten from kindergarten games to teaching fractions to Shakespearean insults, so I hope there is something to interest everyone.
