All information in a computer is stored and transmitted as sequences of bits, or binary digits. A bit is a single piece of data which can be thought of as either zero or one.

This activity demonstrates how sequences of these two symbols can be used to represent any number. Copyright cC. This lesson and supporting materials may be copied for nonprofit educational use only. Part of this lesson was adapted from a freely available sample lesson in Computer Science Unplugged cby Bell, Witten, and Fellows. Script for your reference, for guiding children to discover binary numbers.

Have the students make these as binary lesson ideas below. Copy of the Secret Numbers worksheet for each student. Help Cinda Get To School worksheet for each student. Binary Piano craft worksheets as desired. Binary magic trick handouts as desired. Counting to on Your Fingers worksheets as desired.

The first part of this lesson is a discovery exercise which should stimulate binary lesson ideas to learn to count in binary, as well as to reinforce their understanding of place value.

You should review the questions in the script before leading the discussion with your students, but don't feel like you have to memorize the whole thing. Keep the script handy! Also note that your discussion will probably not follow the script exactly. It is provided as a guide to help you keep your discussion on track. The dialogue took place between Rick Garlikov and a class of 3rd graders.

Explain the motivation for the lesson, and tell the students that we're now going to play some binary lesson ideas which will give us practice in writing binary numbers. Divide students into small groups optional - this lesson can be done by individuals, pairs or small groups.

Distribute flash cards, one set to each student or group. The first time you do this lesson you'll have to have the students make their cards. The set should look something like this example: The large cards are approximately 3in x 4in, and the small squares are 2. Note that binary lesson ideas small cards have a zero on one side and binary lesson ideas one on the other. Binary lesson ideas students sort the cards in descending order so binary lesson ideas the largest is binary lesson ideas the left and the smallest is on the right.

High school kids should say something like "powers of 2. Another fun binary lesson ideas to point out is that each card is one more than the sum of all the cards lower than it. Have the students turn over the cards so the numbers are hidden. To reinforce their memory of the different place values call out numbers for them to "find.

Some students might point out that they don't have 3, but they do have 1 and 2. Do a couple other sums which involve 2 cards, then move to 3 cards, etc. Now flip the cards back over so that the number is showing. Call out a number, and have the students place 1s above the cards which sum to that number, and 0s above all other cards.

For example, if you say 11, students place 1s above cards 8, 2, and 1, and 0s above 16 binary lesson ideas 4. If some students find the answers quickly, challenge them to find another solution they won't be able to do so. Have older kids turn over the flash cards after the first example so they get to practice remembering the values. Ask if anyone in the class has a system for finding an answer.

Upper grades should have done so. Request that a student demonstrate the system to the group quickly. A good method for doing this is to subtract the largest power of two you can from the original number, then subtract the largest binary lesson ideas of two you can from that number, then subtract the largest power of 2 you can from that number, etc.

Then, write 1s in the places of the powers of two you subtracted and 0s elsewhere: Older kids should see the binary expansion as a sum of products where the decimal value is equal to the sum of each binary digit multiplied by its corresponding power of 2. Spend a few minutes reemphasizing the connection between binary numbers to decimal numbers.

For example, the decimal value is equal to four s plus five 10s plus three 1s. Similarly, the binary value is equal to one plus one plus one 64 plus one 4 plus one 1. You may want to point out that just as the place values in the decimal representation are powers of 10, the place values in the binary representation are powers of 2. What number is binary ? Try to have the advanced students visualize the cards. Can we do all numbers up to the maximum discussed above?

We won't go all the way to That would take too long. Instead we'll go to Each of these 4 students represents one of the flash cards used in the earlier exercises. Have the remaining students direct the 4 students to show 0s or 1s, and sit or stand accordingly.

Start with 0, all 4 students should show binary lesson ideas, and be seated. Next do 1, students should showand the rightmost person should stand up. Then 2 should beetc. Try to elicit a system for incrementing the numbers. Point out that this system is like adding 1 each time. Younger kids may not see a system. Can all numbers be represented using only 0s and 1s if I gave you enough cards? What's a simple proof of this?

Ones and zeros are not binary lesson ideas written on the hard drive or transmitted over the modem. Rather, they are represented by a magnetic orientation of the binary lesson ideas on a hard drive, and by high and low tones in data transmission.

Since bits by themselves binary lesson ideas represent much information, they are commonly stored together in groups of size 8 called bytes. Distribute the Secret Numbers worksheet for students to complete. Each student creates a secret number and gives it to a friend to decode.

Then the original student checks the decoding and binary lesson ideas the remainder of the worksheet, which also prompts thought about what numbers in base 3 would be like. The second part asks for deeper understanding of the notion of place value. This lesson extends gracefully into a discussion of bases and number systems. Have the students develop a base 7 number system and practice writing numbers binary lesson ideas that system.

Compare the number of digits used to represent a number in base 7 with the binary lesson ideas of digits used to represent a number in base 2. Advanced students may be able to prove that a binary representation is unique. How high can you count if you use your toes as well? Allow students to discover certain pleasant characteristics of binary numbers.

For example, to multiply a binary number by 2, simply add on another 0 in the least significant rightmost bit. How can you divide by two? What binary lesson ideas is represented by 1?

What is the pattern? What number is represented by ? Which of binary lesson ideas characteristics have analogs in other bases? What base would an alien use to contact us initially? Assuming the alien doesn't know that our numeric system is decimal, the alien would use unary just 1s as a tally of the values. Suppose the alien counts in base If the it communicated to us in base 13, we wouldn't be able to recognize the values.

Higher grade students should be asked to articulate the difference between numbers and binary lesson ideas representations. Have two students stand binary lesson ideas with 5 chairs between them.

Ask one to walk to the other, going left or right around each chair. See the Help Cinda get to School handout associated with this activity. How many ways to do this are there? The answer will become more clear if you place a tag on the floor reading "0" to the left of each chair, and reading "1" to the right of each chair, and then ask the children to write down the sequence that they spell out during their walk.

How many ways to make a pizza are there, if there are 7 different toppings? This extends nicely into a lesson on elementary combinatorics: How many ways are there to get dressed if you can choose between 3 pairs of pants, 5 shirts, and 4 pairs of shoes?

Video games immerse users in a world of high tech thrills, stunning visuals, unique challenges, and interactivity. They enable users to become a warrior princess or a gruesome ghoul, create a virtual persona, or even develop worlds that other gamers can play on.

But before the games of today became reality, they were the dreams of a few innovative individuals. Roberta Williams is considered one of the pioneers of gaming as we know it today. Did you know that computing has been used in military espionage and has even influenced the outcome of major wars? As per the words of Winston Churchill, this would remain the single largest contribution to victory. In addition, he laid the groundwork for visionary fields such as automatic computing engines, artificial intelligence and morphogenesis.

Despite his influential work in the field of computing, Turing experienced extreme prejudice during his lifetime regarding his sexual orientation.

Sue Black has demonstrated the power of social networking. She used Web 2. She has also been an active campaigner for equality and support for women in technology fields, founding a number of online networking platforms for women technology professionals. A keen researcher, Dr. Black completed a PhD in software measurement in Her research interests focus on software quality improvements. Black set up The goto Foundation, a nonprofit organization which aims to make computer science more meaningful to the public, generate public excitement in the creation of software, and build a tech savvy workforce.

Read Sue's blog about The goto Foundation: Cleve Moler improved the quality and accessibility of mathematical software and created a highly respected software system called MATLAB. He was a professor of mathematics and computer science for almost 20 years at the University of Michigan, Stanford University, and the University of New Mexico. These packages eventually formed the basis of MATLAB, a programming environment for algorithm development, data analysis, visualization, and numerical computation.

It is difficult to imagine a time when computers were not capable of sharing information and resources with great ease. Sandra Lerner pushed the boundaries of network computing as one of the co-founders of Cisco Systems, which introduced one of the first commercially viable routers. To avoid the tedious task of transferring information between computers using floppy disks, she and co-founder of Cisco, Leonard Bosack, created a local area network, or LAN, between their campus offices using a multiprotocol router that Bosack developed.

Shortly thereafter the pair started Cisco Systems, and began selling the router which was a success, because it could work with so many different types of computers. After Leaving Cisco in , Lerner started the trendy cosmetics company Urban Decay and became a philanthropist and avid activist for animal rights.
