January puzzle answers

Two winners in Math Mania contest

Two kids figured out all of the correct answers to the January Math Mania questions. The puzzles were aimed at getting you to know the correlations between yards and miles and inches and yards.

The two who got all the answers correct were: Ryan Wahidi of Creve Coeur and Hannah Frederick of south St. Louis.

Both will receive a $10 Border's gift certificate.

The number of entries was down in January, probably because many of you didn't get back to school from the holiday break until close to the contest deadline.

Now that you're back, you'll have more time to figure out the February Math Mania questions. If you'd like to enter this month's contest, click here.
