Who we are at the IEEE Computer Society
IEEE and IEEE Computer Society
What is the IEEE (pronounced eye-Triple E)?
The Institute of Electrical and Electronic Engineers Worldwide professional association of engineers from most industries.
• Started as AIEE - 1884• 1963: Became IEEE • Today, 370,000 society members in 160 countries- 30,000 members in Texas
What is the IEEE Computer Society?• The world’s leading organization of computing professionals• Founded in 1946, and the largest of the IEEE’s 38 societies• Nearly 85,000 members• Serves software engineering community with:
• Certifications• Online courses• Software development standards, • Technical journals, books, conferences, conference publications, and

MISSIONOf the Houston Section Committee
To provide Pre-University teacher in-service programs (TISP) and
Support to help improve student interest in Science, Technology, Engineering and Math, and to encourage careers in STEM fields.

What is the Problem with Math and Science?
Perceptions and Miss-Conceptions
What is the Problem with Math and Science teaching in general? Only Math and Science are tested Teachers do not have time for engineering and technology Teachers are not fluent in the ability to teach STEM General lack of spatial skills Classroom environments do not support engineering projects
How are STEM-related careers generally perceived by teachers and students? Usually perceived as being too hard Girls in general do not appear to be interested in STEM subjects Other types of careers are seen as easier and better

Binary Bytes and Computer Applications
The binary numeral system (base 2 numerals) represents numeric values using two symbols,
0 (off) 1 (on)
Electronic circuitry, the binary system used internally
Computers in most products

Lesson Plan 1
Give Binary a Try
Computer memory cell stores binary numbers in groups of eight bits (a byte)
Fundamental level computers are just machines for flipping binary digits on and off.
Computer stores information represented in numerical form.
Computers have trillions of bytes of memory.

Lesson Plan 1

How Does It Work?
Compare binary with our usual numbers.
Base ten system, the decimal system, has 10 digits.
Each position is represented by one of ten possible symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.
When we begin counting values, we start with the symbol 0, and proceed to 9. We call this the “ones” or “units” place.

How Does It Work?
Base two system, binary, has two symbols: 0 and 1. Walking model – Alien or Being:
Aliens are numbers that do not exist in the world.
1. On paper plates write a 0 on one side and a 1 on the other.
2. Or draw an Alien on one side and a 1 on the other.
3. Count and Add Binary Numbers
V.4.0D 5/2/1121
KID’s MATH NOTES: Counting means adding 1 to the previous number.Out of symbols in a numeral system, "move to the left" one place and use a "1" to represent the ”next" place.Reset the symbol in the ”previous” place back to the first symbol, zero.

How Does It Work?
Compare representing numbers in binary and decimal systems. In each world you have power.The column to the left has the highest power and the column on the
right has 0 power. In all number systems 0 power = 1.
Power 3 2 1 0
Base 10 10 10 10
Process 10*10*10 10*10 10*1 1
Value 1000 100 10 1
Power 3 2 1 0
Base 2 2 2 2
Process 2*2*2 2*2 2*1 1
Value 8 4 2 1
Are you doubling
numbers when
multiplying by 2?

Representing numbers:
How Does It Work?
Power 3 2 1 0Base 10 10 10 10
50 = 5*10 + 0*1
356 = 3*100 + 5*10 + 6*1
4720 = 4*1000 + 7*100 + 2*10 + 0*1
Power 3 2 1 0Base 2 2 2 2
3 = 1*2 + 1*1
4 = 1*4 + 0*2 + 0*1
9 = 1*8 + 0*4 + 0*2 + 1*1

How does it work?
Which light are illuminated will determine the hour, minute, and seconds.
The time below is 10 hours, 37 minutes and 49 seconds.
This is brain exercise and teaches
head math and seeing patterns.

Past and Future Lessons …. HTML and Hexadecimal CodePast and Future Lessons …. HTML and Hexadecimal Code
Binary had 2 symbols: 0, 1 Decimal has 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexadecimal has 16: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
o RGB Color is what it is used for: bgcolor.html
Tags: <html><body bgcolor=“FF3300”>
o View the Source of any webpage and you will see HTML Code.o Writing blogs you can toggle between visual and HTML.
WHY learn this? Visual hooks kids on writing.
