Six Math Mania puzzles for October

The Math Mania competition got off to a good start in September. There were lots of entries and 27 kids got all the answers correct.

That's one of the fastest starts in the history of Young Saint Louis.com's math puzzles.

Now, the question is: Are you guys too smart or was Ms. Math Mania too lenient? I guess we'll find out this month.

In October, Ms. Amy Ruzicka, the math teacher at St. Gabriel School, has increased the number of puzzles to six. And, they are a different style from last month.

Let's see how you do. If you have friends who haven't entered, tell them about the monthly feature and have them enter. Maybe they'd like to have fun with math too.

The rules for Math Mania are the same as last year. Each month, the contest calls for you to give answers for five or six math brainteasers.

Then, you can submit your answers, using the form attached to the questions. If you answer all the questions correctly, you'll have a chance to win a Borders book certificate.

We'll award from 2 or 3 $10 book certificates each month, if there are enough winners.

Because there were so many kids with all-correct answers in September, YSL.com is awarding three book certificates. The winners in a random drawing from all the correct entries are:

Sydney Wright, 12; Scott Burns, 11,
and Jackie Migneco, 13, all of St. Louis.

To enter the October Math Mania competition, fill out the attached entry form and give answers to the six questions. Be sure to follow instructions when compiling your entry.

In the November YSL.com edition, we'll publish a new set of teasers. We'll also include another article giving the answers to the October puzzles. We'll publish names of any Borders book certificate winners.

How to enter:

  1. Print out the following entry form.
  2. Fill out your name, address and telephone number.
  3. Answer all six of the November Math Mania questions.
  4. Put your completed entry into a stamped, addressed envelope.
  5. Mail your entry to:
