web page upon arriving to class, go to your class web page, and follow the
directions for today.
Homework
Policy:
All assignments will be due on the deadline date given. It is the
responsibility for all students to complete their assignments on time. Any
assignments received late will not be accepted and a grade will not be given for
that assignment.
Accessing

week’s Class Web Page in case you need to revisit due to an absence, or
you’re required to make up, or catch up on your course assignments.
Homework Assignment: Daily homework assignments may be found at the end of each
day’s agenda. Daily Journal Entries as seen in Daily Ticket to Leave are to be

hours
To
Be Completed by December 22, 2017
This
Week’s Agenda:
UNIT 1: The
Internet:
This unit begins exploring the technical challenges and questions that arise
from the need to represent digital information in computers and transfer it
between people and computational devices.
Topics
include: the digital representation of information - numbers, text, images, and
communication protocols.
In
the second half of the unit, students solve problems similar ones that had to be
solved to build the real Internet. Students design their own versions of
protocols, each one layered on the previous one, in a process that mimics the
layered sets of protocols on the real Internet. Topics include: the digital
representation of numbers and text, Internet Protocol, DNS, and TCP/IP.
Chapter 1: Representing and Transmitting Information
Big Questions
·
Why do computers use binary to represent
digital information?
·
How does data physically get from one
computer to another?
·
Are the ways data is represented and
transmitted with computers laws of nature or laws of man?
Enduring Understandings
·
2.1 A variety of abstractions built upon
binary sequences can be used to represent all digital data.
·
3.3 There are trade offs when representing
information as digital data.
·
6.2 Characteristics of the Internet
influence the systems built on it.
·
7.2 Computing enables innovation in nearly
every field.
UNIT 6: AP Performance Tasks
·
This unit contains lessons to help students with
preparation and execution of the AP® Performance Tasks: Create and Explore
·
The lessons in this unit are meant to be taken
piecemeal rather than as a typical unit sequence. Instead of a sequence of
connected lessons, these represent a more modular breakdown of the things you
need to do to:
1) Understand the AP Performance Tasks
2) Make a plan for completing the tasks in the
time allotted and
3) Actually doing the tasks and submitting
Week 2:
Monday Day G - 9-11-17 – Friday Day C – 9-15-2017
Lesson
6 – Sending Numbers
CT - Computational Thinking
2.1 - A variety of abstractions built upon binary sequences
can be used to represent all digital data.
2.3 - Models and simulations use abstraction to generate new
understanding and knowledge.
3.1 - People use computer programs to process information to
gain insight and knowledge.
6.2 - Characteristics of the Internet influence the systems
built on it.
Students will be able to:
·
Describe how to use bits to create a functioning number system
·
Understand the relationship between the powers of 2 and the
number of bits needed to express a number of a certain magnitude. e.g. How many
bits do I need to represent the number “15”, or “32”, or “1492”?
·
Determine, for a given number of bits, both the number of
possible numbers that can be represented and also the range of those numbers
·
Calculate the range of values that can be represented using
binary numbers of a given size in bits.
·
Invent a simple communication protocol for sending a list of
numbers that represent coordinates on a cartesian grid.
·
Use the Internet Simulator to send the list of points that make
up the drawing to a friend.

Review
Binary Number System – Period 6 Students will teach those who missed Friday
Number
systems help us express and reason about quantities. Early number systems were
merely a system of tallies that allowed humans to record and perform simple
arithmetic with values. The number system we use today uses the concept of place
value to allow us to express any value we wish by combining only 10 symbols (0,
1, 2 …). We therefore call it a “base 10” number system. When developing a
number system for a computer, we only have two symbols available to us,
corresponding with the two states of a single bit. However, the power of place
value allows our binary or “base 2” number system to express any value we
wish.
When
using this binary representation of numbers, certain values (1, 2, 4, 8, 16,
etc.) are seen repeatedly. When written in binary, these values are 1, 10, 100,
1000, 10000, and so on, and so are the incremental place values in this binary
number system

2)
Click
on the ‘File’ icon and read the introduction. You will also need to open the
corresponding activity guides found at the bottom of the introduction. Save a
copy of the guide to your Google Drive so that you will be able to submit to the
Google Classroom Assignment.
3)
Make
sure to clearly define with your partner the protocol you will be using on the
activity guide which I have printed out for you.
4)
When
you are ready each person of each team will secretly plot out the 5 point
drawing on the graph activity sheet I have handed out to you.
5)
When
ready each person of each team will use the internet simulator to send the
coordinates of the points for their drawing to each other. Upon receiving the
transmitted numbers you should plot the points on your graph paper and we will
compare each plotted graph to see if the numbers were sent and received properly
in order to determine how well your protocol worked.
6)
Depending
on the results you may need to go back and refine the rules of your protocol to
correct any problems that you encountered, and then try again with a different
set up coordinates and a new drawing.
7)
Once
successful you will need to exchange the rules of your protocol with another
team and we will see if the team receiving your protocol can successfully
execute your protocol with their partner and successfully use to complete the
task.
Additional
Questions: Now you should change your protocol as necessary to accomplish the
next two tasks
Assessment
for/of learning: Completion of today’s class assignment.
Summarizer: Mr. PC will review each day what each student accomplished and the focus of tomorrow.

Direct Instruction:
In previous lessons we explored how to encode numbers in binary,
and you also developed protocols for sending a list of numbers. Today we’re
going to take that method one step further and look at how we can encode text
with a binary representation. Hopefully you are beginning to realize that if we
can figure out a way to represent information as a set of numbers, then we can
encode it in bits and store that information in a computer or send it over the
Internet
We can encode characters found in text using a standard encoding
that is called the American Standard Code for Information Interchange or ASCII (pronoucned:
“Ask-ee”).
A sample Ascii chart may be viewed by clicking on the following
link:
Introduction:
“What if you wanted to send formatted text that
included things like the ability to underline, bold, or italicize
words....specify a different font size, or color?”
Today
your challenge is to:
You will also notice
that the Internet Simulator has been updated so that you can now type ASCII
text characters to send
Work with your partner from last week to develop a protocol that
allows you to send formatted text.
Both the text and the formatting instructions must be derived
from the printable ASCII character set (i.e. codes 32-126).
Your
protocol must encode at least:
Iteratively test your
protocols to make sure that you have not overlooked any gaps in your protocol.
·
You will send a message and the recipient must be able to
faithfully draw (or produce in some fashion) the formatted text, based only on
the data she received. Here’s a sample message:
NOTE:
Make sure you document in detail your protocol for sending formatted
text. You will be expected to demonstrate your protocol upon my return.
Also, you should be ready to present your Explore Performance Task on Friday. Good Luck and Have Fun!
