TESTIMONIAL
LETTERS
- Mr.
Watt,
- I
just
wanted
you
to
know
that
I
am
using
Check
Digits
with
my
third
grade
class
and
it
is
the
best
thing
that
I
have
seen
come
along
in
math
since
I've
been
teaching.
I
share
it
with
everyone
I
know
and
their
amazement
has
been
the
same
as
mine.
Not
only
is
this
a
good
method
for
checking
work,
but
it
helps
the
children
practice
addition
and
subtraction
facts.
My
kids
will
borrow
from
a
number
or
add
to
a
number
to
make
it
a
9.
Thank
you
again
for
coming
up
with
this
great
method
to
check
your
work.

- Dear
Mr.
Watt
- I
want
to
thank
you
for
writing
this
book.
It
has
helped
my
daughter
Vicki
very
much.
Let’s
just
say
she
was
a
D
and
F
student
in
4th,
5th,
and
6th
grade.
Now
she
is
a
7th
grader
and
she
made
the
honor
roll
in
math,
and
she
is
now
doing
Honors
8th
grade
math.
She
loves
math
and
wishes
you
made
other
books.
If
she
is
confused
about
something
she
will
look
over
the
book
and
see
if
it
can
help
her
before
she
runs
to
the
teacher.
I
am
personally
glad
you
made
this
book,
for
I
am
not
good
in
math
and
have
NO
idea
how
to
help
her
in
this
type
of
math.
I
know
its
going
to
get
harder
and
I
hope
you
will
make
more
to
help
her
along
when
she
enters
high
school.
- Thank
you
again.

She
was
also
asked
to
enter
this
math
competition
in
Morris
in
a
few
weeks
for
her
school
.

- Michele,
- Don't
know
if
you
remember
me
or
not,
we've
met
at
skating
and
other
homeschooling
events
before.
Anyway,
I
just
wanted
you
to
know
that
I
bought
this
book
after
reading
your
message
and
info
at
the
website
and
so
far
we
are
VERY
pleased
with
it.
It
is
really
amazing
how
it
works!!
My
daughter
even
likes
the
lessons
and
is
already
(after
only
one
week!)
doing
better
in
math!
- Thanks
so
much
for
sending
this
info!!!

- Dear
Mr.
Watt,
- A
fellow
home-schooler
shared
about
your
book
&
we
just
wanted
you
to
know
that
it
is
already
making
such
a
difference.
THANK
YOU
SO
MUCH!
I
have
been
spreading
the
word.
My
daughter
is
15
&
has
many
learning
differences.
She
caught
on
quickly
and
is
feeling
much
better
doing
math.
We
have
had
many
high
fives,
especially
with
multiplication
of
hundreds
which
has
always
been
so
frustrating.
Can't
wait
to
try
division.
I
can't
thank
you
enough!
- Many
blessings,

MATH
TEACHER'S
OPINION
- Bill
Petersen
is
a
retired
high
school
math
teacher
and
currently
coaches
the
Naperville
North
High
School
Math
Club
in
Naperville
School
District
203.
The
Naperville,
IL
school
system
has
been
rated
as
the
top
school
district
in
the
United
States
for
math
and
is
continually
rated
in
the
top
95%
of
national
testing.
Mr.
Petersen
is
a
2005
recipient
of
the
Mathematical
Assoc.
of
America's
Edyth
May
Sliffe
Award
for
Distinguished
High
School
Mathematics
Teaching
.
- Mr.
Petersen
calls
Eliminating
Careless
Error
"amazing"
and
says,
"It
allows
you
to
simply
check
the
four
main
areas
of
adding,
subtracting,
multiplying
and
dividing
and
is
laid
out
in
a
way
I
feel
is
easy
to
understand.
I
think
the
book
helps
erase
the
'ugly
monster'
some
see
math
becoming
and
helps
kids
have
success,
which
is
the
key."

- THE
AFFIDAVIT
OF A
DOCTOR
OF
MATHEMATICS
- "The
book Eliminating
Careless
Error
is a
welcome
and
long
overdue
addition
to
the
general
library
of
mathematics
resources.
A
child
learning
this
method
will
find
that
all
numbers
follow
a few
simple
geometric
patterns.
They
will
begin
to
understand
there
is an
important
element
of
simple
form
within
basic
number
theory
that
is
currently
missing
from
primary
educational
material.
The
method
is
presented
clearly
and
in an
entertaining
manner.
It is
complete,
with
guidelines
for
instructions,
exercises,
and
sample
problems.
Parents
can
feel
confident
teaching
this
method
to
their
children
with
this
book."
