About Me
I am Helen L. Wong and I teach at John F.
Kennedy Middle School, in El Centro, California. This
was my 21st year teaching the same grade level. I
work with sixth graders.

About this Lesson
In this lesson I used Technology to introduce the
addition and subtraction of integers using number lines
and chip boards. This is one of California’s State
Standards in Mathematics to be presented to students
at the sixth grade level.

My Expectations
When I began the program, I only expected to
become more competent with Technology as it refers
to my use of it; to further develop lessons to motivate
my students. Little did I realize that this was a new
door opening. This door opened to a room full of
opportunities that widened the spectrum of my
teaching as well as my students’ learning.
I did not realize what was really in store for
me. I thought I was only to learn what was necessary
for me to implement a limited amount of use of
technology in my classroom. Boy, was I wrong!!!

Actual Learning
There were many actual skills that I learned during the
preparation and presentation of this and many other lessons that I
have developed.
I have learned to use Excel to create spreadsheets. I have
spent many hours, and sleepless nights learning the many ins and
outs of presenting an effective lesson using the Powerpoint program,
as well as including all the necessary sound wavs, and animation pics
that are essential to the lesson.
I have also learned how to use various search engines, web
sites, and other resources that are made available everyday on the
internet. It is such a vast treasure trove of information. Along with
the research, I have also learned to upload, download, save, zip,
unzip and defrag with only using the computer,
its printer and a small pen-drive.

Successes
When I began the program, I immediately
realized that if I wanted to develop an effective lesson
to present to my students in which they would acquire
learning, I would need to spend the a lot of time
answering the following question: What do I want my
students to know after they see and go through this
lesson?
This lesson is a visual representation of the
process of adding and subtracting integers. After this
lesson, the students will be able to understand the terms
in the “red” and in the “black” as well as know how to
add or subtract integers by just remembering the
movement of the chips on the chipboard.

Shortcomings
* It is a lesson that takes more than
one 45 minute period to complete.
* Preparation of chipboards and chips
are necessary for this lesson to be
effective.
*Students work in cooperative groups
to assist each other.

Student Data Continued
*The comparison of the Pre-test with the Post-test indicates that
students acquired and ultimately learned the processes of addition
and subtraction of integers.
*In
the Pre-test, students had very little knowledge of either
process. Just a small percentage of students had knowledge of
both processes. After the Post-test, there was a great increase in
the learning growth of the majority of my students. Big Difference!
*Students also felt very proficient in their learning and in their
Post-test results. They were very pleased to compare both tests
and see that they grew in their learning. This promoted further
motivation from the students to continue with
their learning of the multiplication and division process of
integers.

Lesson Revisions
•I plan to give the students more time to
explore and work with the chips and
chipboard as well as with drawing number
lines.
• I also would like them to make a poster
which would demonstrate visually and in
written form their explanation of both
addition and subtraction of integers.
•The Pre-test is a good diagnostic tool
because it determines the amount of
information that the students know before
you begin the lessons and that will direct
the teaching and lessons that you need to
present to the students.

My Experiences in the program are never
ending. It is the beginning of a new stage in my
teaching career. I am no longer frustrated trying to
find lessons to reach the various modalities in which
students learn. My job as a teacher is to facilitate
experiences or opportunities in which my students will
be motivated to find out more….I also am there to
provide them with the immense fountain of resources
available to them for this learning process.
I began creating lessons in Mathematics
because it is the easier subject to demonstrate and
explain. But, now I am utilizing the resources available
and am preparing lessons for Social Studies, Language
Arts, Writing and many others for this upcoming year.
The only thing that stops me is the lack of time that I
really need to find everything possible for my lessons.
But I know that as time goes by, I will become even
better.

Concluding Statement
I am already looking forward to sign up for more Technology
classes so that I may become more knowledgeable and prepared to
teach my students what I know to them. That might be a bit
difficult because some of these students have more Technological
savvy than many adults. I might learn more from them than they
from me. Not only that, there is a young teacher that has been
challenged by what I have learned in Technology during the past 7
years. Since he was the one that first taught me how to use my
first classroom computer, and now I know a bit more than he does.
I plan to utilize what I know to bring the “World” to my
students so that they may have the same opportunities that other
students have in better schools, larger cities, and higher socioeconomic settings. I refuse to let those minor setbacks stop my
students’ learning. This program has given me the
motivation necessary to do this for MY
kids.
