Some
December Math Puzzlers
similar to past questions
Mr. Math Puzzler
is giving you a chance to learn from some of his past questions.
Several of the December Puzzlers are ones that are similar
to questions in previous months.
That will give
you an opportunity to look at past issues and find similar
questions and how they were answered.
Mr. Wayne Hesse
is our Mr. Math Puzzler. He's an eighth grade math teacher
at Green Park Lutheran School in south St. Louis County.
Since starting
the Math Puzzler competition in September, 2001, Mr. Hesse
has come up with over 160 Math Puzzlers. Some have been easy
but some others have been quite hard.
Since winners
have been hard to come by in the last two months, this series
of questions that look like past ones give you a chance to
catch up with Mr. Math Puzzler.
The similar questions
will be especially good for kids who are trying the Math Puzzlers
for the first time.
To catch on to
the pace of the Puzzlers, go to the Past Stories tab
at the top of the home page. Then, pick any month after September,
2001, to check on past Math Puzzlers. The questions are one
month and then the answers are published the next month.
(For example,
to check last month's questions, click on November, 2003.
Then, to check your answers, click on the answer story on
this edition.)
When you are ready
to enter the December contest, come back to his story, fill
out the entry blank, answer the Puzzlers and mail in your
entry.
If any of our
contestants get all six answers correct, we publish their
names in the following month. That's also the time when we
give the explanations for the previous month's questions.
Also, as an added
incentive, we enter all kids who get six right answers into
a drawing for $10 Border's book certificates. Up to three
certificates will be awarded each month.
A reminder:
These Math Puzzlers can be quite challenging, especially for
younger kids. Remember, we don't mind if you get help from
a parent or older brother or sister. In fact, you might want
to make this a family activity.
