MIDDLE SCHOOL MAl7-f WITH PIZZAZZ!
is a series of five books designed to provide
practice with skills and concepts taught
in today's middle school mathematics
programs. The series uses many of the
same puzzle formats as P R E - W E B R A
WITH PEZUZ! and ALGEBRA WlH P m !
both published by Creative Publications.
3. CAREFUL SELECTION OF TOPICS
AND EXERCISES. The puzzles within
each topic area are careefully sequenced
so that each one builds on skills and
concepts previously covered. The
sequence of exercises within each puzzle
is designed to guide students in incremental, step-by-step fashion toward
mastery of the skill or concept involved.
A primary goal is the development of
problem-solving ability. In order to solve
problems, students need not only rules
and strategies but also a meaningful
understanding of basic concepts. Some
puzzles in this series are designed specifically to build concepts. Other puzzles,
especially those for estimation, also help
deepen students' understanding by
encouraging them to look at numbers a s
quantities rather than just a s symbols to
be manipulated. For puzzles specifically
keyed to problem solving, we have tried
to write problems that are interesting
and uncontrived. We have included extra
information in some problems, and have
also mixed problem types within sets,
so that the problems cannot be solved
mechanically.
We believe that mastery of math skills and
concepts requires both good teaching and a
great deal of practice. Our goal is to provide
puzzle activities that make this practice
more meaningful and effective. To this end,
we have tried to build into these activities
three characteristics:
1. KNOWLEDGE OF RESULTS. Various
devices are used in the puzzles to tell
students whether or not their answers
are correct. Feedback occurs immediately
after the student works each exercise.
For example, if a particular answer is not
in the code or scrambled answer list, the
student knows it is incorrect. He or she
can then try again or ask for help.
Additional feedback and reinforcement
occurs when the student finds a puzzle
solution that is appropriate. This
immediate knowledge of results benefits
students and also teachers, who no
longer have to spend time confirming
correct answers.
In addition to these efforts to make the
puzzles effective, we have tried to make
them easy to use. The topic for each puzzle
is given both at-the bottom of the puzzle
page and in the Table of Contents on pages
iv and v. Each puzzle is keyed to a specific
topic in recent editions of leading middle
school textbooks. Each puzzle requires
duplicating only one page, and many
of them provide space for student work.
Finally, because the puzzles are selfcorrecting, they can eliminate the task
of correcting assignments.
2. A MOTIVATING GOAL FOR THE
STUDENT*The puzzles are designed so
that students will construct a joke or
unscramble the answer to a riddle in
the process of checking their answers.
The humor operates a s an incentive,
because the students are not rewarded
with the punch line until they complete
the exercises. While students may decry
these jokes as "dumb" and groan loudly,
our experience has been that they enjoy
the jokes and look forward to solving the
puzzles. The humor has a positive effect
on class morale. In addition to humor,
the variety and novelty of procedures for
solving the puzzles help capture student
interest. By keeping scrambled answer
lists short and procedures simple, we
We hope that both you and your students
will enjoy using these materials.

NOTES ABOUT USING THE PUZZLES
The selection of topics for MIDDLE SCHOOL
MATH WrrH PIZZAZZ! reflects recent thinking
about what is important in an updated middle
school math program. Virtually every puzzle can
be matched with a particular lesson in recent
editions of popular textbooks. After students
have received instruction in a topic and worked
some sample exercises, you might assign a
puzzle along with a selection of textbook
.
exercises.
Students in the middle grades should begin to
classify many mathematics problems and
exercises into one of three categories:
1 . MENTAL MATH. Problems for which an exact
answer can be obtained mentally.
2. ESTIMATION. Problems for which an
approximate answer, obtained mentally, is
sufficient.
3. TOOLS. Problems requiring an exact answer
that cannot be obtained mentally. Students
will use paper and pencil and/or calculators.
Some of the puzzles in this series focus
specifically on one of these categories. A few
puzzles actually present problems in all three
categories and ask the student to make the
classification.
By the time they reach the middle grades,
students should generally be permitted to use
calculators for problems that require tools
(Category 3).The most common argument
against calculator use is that students will
become overly dependent on them. This concern,
though, appears to be based primarily on fear
that students will rely on the calculator for
problems in Categories 1 and 2, those that
should be done mentally.
To solve problems in Category 3, calculators are
wonderful tools for computing. Students may
also need paper and pencil to make diagrams,
write equations, record results, etc., so they will
need both kinds of tools. On the other hand,
students should not need calculators for
problems in Categories 1 and 2, problems that
call for mental math or estimation'. Skills in
these areas are essential not only in daily life
but also for the intelligent use of the calculator
itself. The puzzles in this series reflect these
three categories and the distinction between
them.
When students do use calculators, you may
want to have them write down whatever
numbers and operations they punch in and their
answers. This makes it easier to identify the
cause of any error and assists in class
management. Even when students do mental
math or estimation puzzles, have them write a
complete list of answers and, where appropriate,
the process used to get the answers. Encourage
students to write each answer before locating it
in the answer list. Students should complete all
the exercises even if they discover the answer to
the joke or riddle earlier.
One advantage of using a puzzle a s a n
assignment is that you can easily make a
transparency of the page and display the
exercises without having to recopy them on the
board. You can then point to parts of a problem
a s you discuss it. It is often helpful to cut the
transparency apart so that you can display
exercises on part of the screen and write
solutions on the remaining area.
